If your project is still at the prototype or design stage, you can also bring the information you currently have. Our team can discuss which additional files or specifications may be needed before quotation and manufacturing review.
For purchasing teams, a BOM and expected production quantities can help start a sourcing discussion. For engineers, PCB drawings, Gerbers, stack-up information, and assembly data can make technical conversations much more specific.
How Can EBest Circuit Support Your PCB-to-PCBA Project?
While PCBA will be the main product presented at electronica 2026, assembly begins with the bare circuit board.
EBest Circuit supports a range of PCB technologies that can continue into component sourcing and assembly within the same project.
Complex routing and higher circuit density; typically 4–20+ layers, 1–2 oz copper, with controlled impedance available
HDI PCB
Compact products and fine-pitch devices; microvia Ø0.10–0.15 mm, laser-drilled vias, 1+N+1 / 2+N+2 structures, via-in-pad available
Flexible PCB
Lightweight and space-limited electronics; typically 1–6 layers, 12.5–50 μm PI, thin copper and dynamic/static bending structures
Rigid-Flex PCB
Integrated rigid and flexible interconnection; typically 4–12+ total layers, 1–4 flex layers, controlled bend areas and impedance available
Metal-Core PCB
Thermal management and power applications; 1.0–3.0 mm aluminum/copper core, typically 1–8 W/m·K thermal conductivity depending on material
Heavy Copper PCB
Higher-current circuits; typically 3–10 oz copper, with thicker copper available for project-specific power requirements
High-Tg PCB
Higher thermal requirements; typically Tg ≥170°C, suitable for higher processing and operating temperatures
High-Frequency PCB
RF and microwave circuits; Rogers/PTFE or other low-loss laminates, with controlled Dk/Df and RF impedance
High-Speed PCB
High-speed digital systems; controlled 50 Ω single-ended / 90–100 Ω differential impedance, low-loss materials and matched routing
Impedance-Controlled PCB
Controlled signal transmission; commonly 50 Ω, 90 Ω, 100 Ω, with typical tolerance of ±10% depending on design
Ceramic PCB
Thermal and specialized electronics; Al₂O₃ / AlN substrates, with thermal conductivity from about 20 to 170 W/m·K depending on material
After PCB fabrication, the project can continue through component sourcing, stencil preparation, SMT, THT, AOI, X-ray inspection, programming, functional testing, conformal coating, cable assembly, and box build according to the product requirements.
The benefit is not simply having several manufacturing processes available. It allows PCB fabrication requirements and assembly requirements to be considered together, especially when a project involves dense component placement, special materials, thermal management, impedance control, or complex testing.
What Can We Discuss Face to Face at electronica 2026?
A face-to-face meeting is especially useful when a project has details that are difficult to capture in a standard RFQ.
At Hall A1, Booth 178, you can discuss your PCB or PCBA project directly with our team, including design requirements, sourcing concerns, assembly challenges, inspection methods, testing, and production planning.
Typical topics include:
PCB and PCBA manufacturability — stack-up, materials, panelization, assembly constraints, and special process requirements.
Inspection and testing — AOI, X-ray, ICT, programming, functional testing, and project-specific test fixtures.
Production transfer — how an approved prototype can move into repeat production with controlled files, components, and process requirements.
Further integration — conformal coating, cable assembly, mechanical assembly, and box build where required.
For example, a BOM may show which component is required, but it does not explain why the part cannot be substituted. A drawing may show where a connector belongs, but not whether its mechanical alignment is critical to the enclosure.
These details can affect sourcing, assembly planning, inspection, testing, lead time, and ultimately production consistency.
That is where a face-to-face discussion can save both sides considerable time.
What Quality Systems Support Our Manufacturing?
For international electronics customers, manufacturing capability also needs to be supported by quality systems, compliance, documentation, and traceability.
EBest Circuit maintains certifications and compliance capabilities including:
ISO 9001
ISO 13485
IATF 16949
AS9100D
UL
RoHS
REACH
SGS
These quality systems and compliance capabilities support projects across industrial, medical, automotive, aerospace, communication, energy, and general electronics markets.
Depending on the project, manufacturing control may include incoming material verification, production records, solder paste inspection, SMT process control, AOI, X-ray inspection, electrical testing, functional testing, traceability, and final inspection.
At electronica, we can discuss how these controls apply to your particular product rather than simply showing certification logos.

From Guangzhou to Munich — EBest Circuit is ready for the next stop. See you at electronica 2026, Hall A1, Booth 178!
From October 15 to 19, 2026, our team welcomed visitors at Booth 16.3H18 in Area C of the China Import and Export Fair Complex in Guangzhou. This year, our exhibition focused on PCB assembly (PCBA), giving customers a closer look at our manufacturing capabilities, assembled circuit boards, quality systems, and electronics manufacturing services.
Throughout the exhibition, we had the opportunity to meet customers, engineers, purchasing teams, distributors, and business partners from different markets. Some visitors came with active PCB and PCBA projects. Others were looking for a new manufacturing partner or wanted to understand our capabilities in component sourcing, SMT assembly, inspection, testing, and complete electronics manufacturing.
To everyone who stopped by our booth: thank you for visiting EBest Circuit at Canton Fair 2026 Autumn.
What Happened at Booth 16.3H18 During Canton Fair 2026?
Canton Fair provided us with something that emails and online meetings cannot completely replace: face-to-face conversations around real electronics projects.
At Booth 16.3H18, our team introduced EBest Circuit, answered manufacturing questions, presented PCBA samples, and discussed new projects with visitors throughout the five-day exhibition.
Our discussions covered different stages of electronics manufacturing, including:
PCB fabrication
Component sourcing
SMT assembly
Through-hole assembly
Prototype PCBA
Volume production
AOI and X-ray inspection
Functional testing
Conformal coating
Cable assembly
Box-build assembly
Many conversations started with an assembled PCB on our display shelf and quickly moved into actual project requirements: board construction, component availability, inspection methods, testing, lead time, traceability, and production planning.
That is exactly what we hoped to achieve at the Canton Fair—not simply show products, but create an opportunity to discuss how those products are actually manufactured.
Why Was PCBA the Main Focus of Our Exhibition?
Our main focus at Canton Fair 2026 Autumn was PCBA manufacturing.
Rather than showing only bare circuit boards, we displayed assembled boards and related samples so visitors could see the types of electronics manufacturing projects we support.
The circuit boards displayed at the booth represented different component densities, package types, connectors, PCB structures, and application requirements.
For many visitors, seeing an actual assembled board made the conversation much more specific. Instead of discussing manufacturing only in general terms, we could talk directly about BGA inspection, connector assembly, component sourcing, thermal requirements, testing, or production scaling.
Watch Our Canton Fair 2026 Autumn Highlights
For customers and partners who could not meet us in Guangzhou, we also recorded some moments from the exhibition. The video below gives a closer look at our presence at Canton Fair 2026 Autumn.
Which Industries Did We Discuss at Canton Fair?
One of the strengths of Canton Fair is the diversity of visitors. During the exhibition, we discussed PCB and PCBA manufacturing requirements for products used across several industries.
Industrial Electronics
Industrial automation, control equipment, sensors, monitoring systems, motor controls, and other industrial products often require stable long-term production and consistent assembly quality.
Automotive Electronics
Automotive projects place greater emphasis on process control, traceability, testing, and manufacturing consistency.
Medical Electronics
Medical-related electronics may require tighter documentation, controlled production processes, traceability, and quality management.
Communication Equipment
Communication products often combine dense component placement, connectors, RF circuitry, high-speed signals, and controlled-impedance PCB requirements.
New Energy and Power Electronics
Energy storage, charging equipment, power conversion, industrial power supplies, and similar products can involve demanding current and thermal requirements.
Aerospace and Aviation Electronics
Aerospace-related projects place particularly high importance on process control, documentation, traceability, and reliable manufacturing.
Meeting customers from these different industries also reminded us that there is no single manufacturing process that fits every PCBA. The board, components, application, operating environment, production quantity, and test requirements all influence how a project should be manufactured.
How Does EBest Circuit Support PCB-to-PCBA Manufacturing?
Another topic that attracted attention at our booth was our ability to support more than PCB assembly alone.
EBest Circuit supports a broad range of PCB technologies, including:
After PCB fabrication, projects can continue into component sourcing, stencil preparation, SMT, THT, inspection, programming, testing, conformal coating, cable assembly, and box build.
This gives customers the option to coordinate PCB and PCBA requirements through one manufacturing project rather than separating each stage among different suppliers.
For engineering teams, this can help PCB manufacturability and assembly requirements be reviewed together. For purchasing teams, it can simplify communication and reduce the number of suppliers involved in one project.
What Quality Systems and Certifications Support Our PCBA Production?
Visitors also asked about the quality systems behind our manufacturing capabilities.
EBest Circuit maintains certifications and compliance capabilities including:
ISO 9001
ISO 13485
IATF 16949
AS9100D
UL
RoHS
REACH
SGS
These certifications help us support customers across general electronics, industrial, automotive, medical, aerospace, communication, and other quality-sensitive applications.
Quality control also extends beyond certificates. Depending on the project, our production and inspection flow can include incoming material inspection, solder paste printing, SPI, SMT placement, reflow, AOI, X-ray inspection, through-hole assembly, electrical testing, functional testing, final inspection, and production records.
The inspection and testing plan is determined according to the actual board and customer requirements.
What Made Canton Fair 2026 Valuable for Us?
Products were displayed on the shelves, but the most valuable part of the exhibition happened in front of them.
It was the conversations.
Customers talked with us about new product development, existing supplier challenges, prototype quantities, component availability, production quality, testing requirements, and upcoming mass-production plans.
Some were beginning entirely new projects. Others were evaluating alternative PCB or PCBA suppliers.
Those conversations provide information that cannot always be found in a Gerber file or BOM. A drawing tells us what needs to be manufactured. A face-to-face discussion often tells us why a particular requirement matters to the finished product.
That understanding helps both sides communicate more efficiently once a project moves into engineering review and production.
Next Stop: Meet Us at Electronica 2026 in Munich
Our 2026 exhibition schedule is not over yet. After meeting customers and partners in Guangzhou, EBest Circuit will next attend Electronica 2026 in Munich, Germany. We look forward to continuing the conversations around PCB, PCBA, component sourcing, testing, and complete electronics manufacturing with customers in Europe and other international markets.
Exhibition: Electronica 2026

The PCB material price increase in October 2026 is adding new cost pressure to circuit board purchasing. On October 13, Kingboard Laminates announced a 15% price increase for copper-clad laminates (CCL) and prepreg (PP) manufactured using 2116 or thinner fiberglass fabrics. The adjustment took effect immediately, reflecting continued supply pressure on electronic glass fabric and other upstream materials.
For PCB buyers, the concern goes beyond higher material prices. Will your next PCB quotation change? Could material shortages extend production lead times? And how can you keep manufacturing costs under control without compromising board reliability?
At EBest Circuit, we provide PCB fabrication, component sourcing, and PCB assembly services. Our engineering team helps customers review material requirements, PCB stackups, manufacturing specifications, and production quantities to identify practical cost-saving opportunities before ordering.
Key Takeaways
The October 2026 Kingboard laminates price increase affects CCL and prepreg using 2116 or thinner glass fabrics, with a 15% adjustment.
A copper clad laminate price increase does not translate directly into the same increase in finished PCB prices.
The copper clad laminate price trend reflects different material grades, glass fabric supplies, copper foil costs, and order conditions.
Compare copper clad laminate price changes against the approved stackup, panel utilization, copper weight, and production quantity.
Material alternatives require technical review and customer approval; forecasts and stable specifications can improve purchasing planning.
At EBest Circuit, we support material selection, DFM, PCB fabrication, and assembly to help customers manage production costs.
What Is the Latest Kingboard PCB Material Price Increase in October 2026?
On October 13, 2026, Guangdong Kingboard Laminates Trading Co., Ltd. issued price adjustment notice No. 20261013, announcing an immediate 15% increase for selected PCB materials.
The adjustment covers copper-clad laminates and prepreg manufactured with 2116 or thinner electronic fiberglass fabrics. Kingboard attributed the increase to strong market demand, tight upstream supplies of electronic glass fabric and fiberglass yarn, and significant increases in associated material costs.

Stated reasons
Strong demand, tight glass fabric and fiberglass yarn supply, rising material costs
The latest adjustment follows a series of price increases across Kingboard’s laminate and prepreg product lines during 2025 and 2026. However, the 15% increase applies to the specified material categories, rather than every type of FR-4 laminate or finished PCB.
For companies purchasing multilayer PCBs, this distinction matters. A board’s cost exposure depends on its material construction, approved laminate specifications, and quantity of affected materials consumed during manufacturing.
Why Are PCB Raw Material Prices Rising in 2026?
PCB raw material prices are rising because demand for certain electronic materials is placing pressure on upstream manufacturing capacity and supply availability. Electronic glass fabric, copper foil, and resin systems are essential inputs for copper-clad laminates, and cost changes in these materials can affect PCB fabrication prices.
Electronic fiberglass fabric supply
Fiberglass fabric provides reinforcement and dimensional stability within laminate and prepreg materials. Different glass cloth styles are selected according to thickness, resin content, electrical properties, and stackup requirements. Thin fiberglass fabrics, including 2116, 1080, and other fine styles, are commonly used in multilayer constructions that require controlled dielectric thickness. When these materials become more expensive or difficult to source, laminate manufacturers face higher production costs.
Copper foil cost pressure
Copper foil forms the conductive layers of a PCB. Its cost is affected by copper prices, foil processing requirements, thickness, and product specifications. Boards requiring heavier copper, additional copper layers, or larger panel areas can have greater exposure to copper-related material expenses.
Growing demand for advanced electronics
AI infrastructure, data centers, automotive electronics, communication equipment, and other electronic applications require substantial PCB manufacturing capacity. Some applications also depend on specialized laminate materials, high-layer-count stackups, and controlled electrical performance. These demand patterns can tighten supplies of particular material grades. The degree of impact varies by product category rather than affecting every PCB material equally.
For PCB buyers, the immediate concern is whether the materials specified in their current designs remain available at acceptable prices and lead times.
How Many Times Has Kingboard Raised Prices in 2026?
Kingboard Laminates has announced eight rounds of PCB material price increases in 2026 through October 13, bringing the reported total to 12 rounds since February 2025. These adjustments have affected FR-4 copper-clad laminates, CEM materials, prepreg, and certain copper foil processing charges, with different increases applied according to product type and specification.
The frequency of these increases illustrates the sustained pricing pressure facing PCB material buyers. The latest adjustment is particularly relevant to multilayer PCBs that use thin fiberglass fabrics in their laminate and prepreg constructions.

According to industry reporting, prices for some conventional copper-clad laminates rose from approximately RMB 100 per sheet two years earlier to around RMB 400 per sheet. These figures describe particular market observations and should not be generalized to every material grade, thickness, or supplier.
Because the announcements involve different materials and specifications, their percentages cannot simply be added together to calculate one cumulative increase for all PCB raw materials.
For PCB buyers, the repeated adjustments introduce challenges in material budgeting, quotation validity, production planning, and long-term purchasing costs. Even when a PCB design remains unchanged, the material cost behind a repeat order may differ from that of a previous production batch.
How Does the 15% Laminate Price Increase Affect PCB Manufacturing Costs?
A 15% increase in selected laminate prices does not automatically translate into a 15% increase in finished PCB prices.
A PCB quotation includes raw materials, drilling, copper plating, imaging, etching, solder mask, surface finishing, inspection, electrical testing, and other manufacturing operations. The material portion varies depending on board construction and production quantity.
PCB cost factor
Potential effect of rising material prices
Laminate and prepreg
Higher purchasing costs for affected grades
PCB layer count
More dielectric and copper layers increase material consumption
PCB dimensions
Larger boards generally consume more panel material
Copper thickness
Higher copper requirements can increase material and processing expenses
Stackup construction
Specific prepreg and core requirements may limit available alternatives
Production quantity
Purchasing quantities, panel utilization, and setup costs influence unit pricing
Material availability
Limited supply can affect procurement and manufacturing schedules
Example: How a 15% material increase can affect a PCB quotation
Assume laminate and prepreg represent 30% of a finished PCB’s original manufacturing cost. If all of that material portion rises by 15%, while every other cost remains unchanged, the resulting cost increase would be 30% × 15% = 4.5% of the original PCB manufacturing cost.
This is an illustrative calculation, not an industry-wide PCB price forecast. Actual cost changes depend on material specifications, existing inventory, purchasing arrangements, and manufacturing efficiency. For buyers sourcing multilayer FR-4 PCBs, reviewing the material composition and stackup is often more useful than applying a uniform percentage increase to the entire PCB budget.
Which PCB Types Are More Sensitive to Rising CCL and Prepreg Prices?
Not every PCB design has the same exposure to changing laminate prices. Sensitivity depends on the amount and type of material used, construction complexity, and available approved alternatives.
Multilayer FR-4 PCBs deserve particular attention. These boards typically use multiple core and prepreg layers to achieve their required thickness and electrical characteristics. When a design requires a specific glass fabric style or dielectric construction, a manufacturer must consider both material cost and technical compatibility.
HDI and high-speed boards may also have more restrictive material requirements, although their exposure to this particular announcement depends on the exact materials specified. For procurement teams, the best approach is to identify which current PCB part numbers use the affected material specifications before revising purchasing budgets.
How Can You Reduce PCB Manufacturing Costs During Material Price Increases?
The most effective way to control PCB costs is to review the design and manufacturing specifications before committing to production. Changes to panel utilization, material selection, stackup construction, and order planning may produce savings without changing the intended function of the board.
1. Review your PCB stackup and laminate requirements
Ask your PCB manufacturer to check whether the proposed stackup uses material grades that are necessary for the design. For standard FR-4 applications, there may be more than one suitable core and prepreg construction. However, any proposed substitution must preserve the required overall thickness, dielectric properties, electrical performance, thermal characteristics, and reliability. For impedance-controlled boards, a change in dielectric thickness or material properties may require trace geometry adjustments and renewed impedance verification.
2. Improve PCB panel utilization
Manufacturers process PCBs using production panels. The arrangement of individual boards on a panel directly affects material utilization. Optimizing board orientation, spacing, and manufacturing panel design can help reduce material waste. For projects with relatively large production quantities, even modest improvements in panel utilization can influence the total manufacturing cost.
3. Evaluate unnecessary design complexity
Additional layers, excessive copper thickness, specialized materials, and demanding manufacturing tolerances can increase fabrication costs. A design review should distinguish between requirements that are electrically or mechanically necessary and specifications that may be more restrictive than the application requires. For example, an unnecessarily tight dimensional tolerance can introduce manufacturing difficulty without improving product performance.
4. Plan production quantities more carefully
Small prototype batches and volume production have different cost structures. Combining planned demand into an appropriate production schedule may improve purchasing efficiency and reduce repeated setup expenses. The right order quantity should reflect actual demand, inventory carrying costs, approved design revisions, and production forecasts.
5. Request a DFM review before placing an order
A design for manufacturability (DFM) review can identify material constraints, fabrication risks, and cost-saving opportunities early. It is particularly useful when moving from prototype production to higher-volume manufacturing. An effective DFM review should cover material selection, stackup construction, drilling specifications, trace and spacing requirements, copper distribution, panel utilization, and test requirements.
6. Compare total manufacturing cost, not only board price
The lowest unit quotation does not always provide the lowest overall project cost. Rework, rejected boards, production delays, transportation expenses, and inconsistent quality can reduce apparent savings. Evaluate suppliers according to manufacturing capability, material compliance, quality control, lead-time commitments, and overall project cost.
Can You Use Alternative PCB Materials to Control Costs?
Alternative PCB materials may reduce manufacturing costs when they satisfy the original design’s electrical, mechanical, thermal, and regulatory requirements. For example, a standard industrial control board may have more material flexibility than a high-speed communication PCB requiring a specific dielectric constant and loss tangent. Material substitutions should therefore be evaluated against the application rather than price alone.
Material property
Why it matters before substitution
Glass transition temperature (Tg)
Affects thermal performance and processing suitability
Decomposition temperature (Td)
Relevant to thermal exposure and material reliability
Dielectric constant (Dk)
Influences impedance and signal propagation
Dissipation factor (Df)
Contributes to dielectric signal loss
Coefficient of thermal expansion (CTE)
Affects dimensional stability and plated-hole reliability
Material thickness
Determines stackup geometry and mechanical dimensions
Flammability classification
Must satisfy applicable product safety requirements
Approved material specification
May restrict substitution in qualified products
For medical, automotive, industrial, and other reliability-sensitive applications, material changes may require customer approval and additional qualification testing. A lower-cost material is useful only when the finished PCB continues to meet its required performance and reliability criteria. Buyers should request written confirmation of proposed substitutions and their technical implications before releasing a revised production order.
Will PCB Material Shortages Affect Manufacturing Lead Times?
PCB material shortages can extend production lead times when a manufacturer cannot obtain the approved core, prepreg, copper foil, or specialized laminate within the planned purchasing schedule. The impact depends on material availability, supplier stock, order quantity, and whether an approved alternative is available.
A PCB may have a relatively short fabrication cycle once materials are ready, but procurement delays can affect the overall delivery schedule. To reduce this risk, buyers should provide the following information when requesting a quotation:
Approved material specifications: Identify mandatory material grades, brands, and permitted equivalents.
Production forecast: Indicate prototype quantities, expected repeat orders, and volume requirements.
Required delivery schedule: Specify the target shipping or delivery date.
Qualification restrictions: Identify applications requiring customer approval before material changes.
These details allow manufacturers to assess material availability and production feasibility before confirming a delivery commitment. For repeat production programs, early coordination between engineering, purchasing, and manufacturing can reduce the risk of unexpected material-related delays.
How Can You Secure More Stable PCB Pricing for Repeat Orders?
Stable PCB purchasing requires more than requesting a fixed unit price. Buyers should establish a clear understanding of material assumptions, quotation validity, production quantities, and the conditions under which prices may change. The following purchasing practices can improve cost visibility:
Confirm quotation validity
Ask how long the quoted price remains valid and whether it depends on current material availability. A quotation based on existing inventory may have different conditions from one requiring new material procurement.
Provide realistic volume forecasts
Expected monthly, quarterly, or annual quantities can help manufacturers evaluate purchasing requirements and capacity planning. Forecasts are particularly useful when a project has stable specifications and predictable demand.
Control PCB revisions
Frequent revisions can make long-term material purchasing more difficult. Maintaining clear revision control helps manufacturers distinguish approved production configurations from designs still undergoing development.
Discuss material purchasing arrangements
For stable production programs, buyers may discuss scheduled releases, reserved materials, or other purchasing arrangements with their manufacturing partners. Any such arrangement should define responsibilities, quantities, pricing conditions, and inventory commitments.
Review cost changes with technical context
When a PCB quotation increases, request clarification about the affected materials or manufacturing requirements. This provides a stronger basis for cost evaluation than comparing the percentage increase alone.

Frequently Asked Questions About PCB Material Price Increases
Q1: Will PCB prices continue to rise throughout 2026?
A1: PCB prices may remain under pressure where laminate, fiberglass fabric, copper foil, or other material supply remains constrained, but future changes depend on market conditions and product specifications.
Q2: Does the Kingboard 15% increase apply to every FR-4 PCB?
A2: No. The October 13 announcement concerns CCL and prepreg manufactured using 2116 or thinner fiberglass fabrics, rather than every FR-4 PCB construction.
Q3: Is 2116 fiberglass fabric the same as a 2116 PCB laminate?
A3: No. 2116 identifies a fiberglass fabric style used within laminate or prepreg constructions; the finished laminate’s properties also depend on its resin system and other manufacturing specifications.
Q4: Can a PCB manufacturer change the laminate brand without customer approval?
A4: Material substitution depends on the customer’s specifications and approval requirements; controlled or qualified products may require formal approval before a change.
Q5: Are PCB prototype prices affected more than mass-production prices?
A5: The impact varies because prototypes and volume orders have different material consumption, purchasing arrangements, setup expenses, and unit cost structures.
Q6: Can ordering larger quantities reduce the effects of PCB material price increases?
A6: Larger production quantities may improve unit-cost efficiency, but actual savings depend on material prices, panel utilization, setup costs, and purchasing conditions.
Q7: What happens if the specified PCB laminate is unavailable?
A7: The manufacturer should identify the supply constraint and discuss approved alternatives or revised delivery arrangements before making changes to the released design.
Q8: Can PCB and PCBA manufacturing be quoted together?
A8: Yes. A combined quotation can cover bare-board fabrication, component sourcing, assembly, and required testing when the necessary production files are available.
The September 7, 2026 GPU shortage snapshot matters to EBest Circuit (Best Technology) when a customer-approved graphics card is part of a Box Build order. RTX 5090 sourcing does not change how we manufacture the surrounding PCBs, but uncertain availability can delay material release, force another mechanical and electrical review, and change the agreed system test. We therefore treat the GPU as a separately approved high-value item within the complete assembly, not as a component that can be substituted by chipset name alone.
What Does the September 7 RTX 5090 Price Snapshot Show?
The observed listings showed a clear difference between Founders Edition reference prices and orderable add-in-board models. This is a dated channel snapshot rather than a market average. Each row preserves the region, seller, exact item, price and availability observed on September 7, 2026.
The same MSI model as the US sample, but currency, tax and regional terms differ.
The figures do not support one universal claim about the RTX 5090 market price. Founders Edition and factory-overclocked AIB cards differ in cooler design, dimensions, power settings and commercial terms. For a Box Build order, the useful conclusion is narrower: the project cannot assume that its approved model will be available at the original budget and delivery date.
Why Does GPU Availability Matter to a Box Build Manufacturer?
A discrete high-end GPU enters the Box Build during system integration, but its availability affects decisions made before assembly starts. We need the approved manufacturer part number and the selected material-supply model before confirming the integration schedule.
Material release: The assembly schedule must reflect when the approved GPU will actually arrive and pass the agreed receiving checks.
Mechanical fit: Card length, height, slot width and power-connector position affect the enclosure, brackets and cable clearance.
Power and thermal inputs: The selected card affects the PSU, connector arrangement, airflow plan and system-level thermal check.
Test preparation: The operating system, driver, display outputs and acceptance load must match the approved configuration.
Change control: A different RTX 5090 model is an engineering change when it alters any of these inputs, even if the GPU family name is unchanged.
This is the direct connection between the news and our manufacturing work. The channel price itself is outside our control; the material handoff, integration inputs and agreed production tests are the parts that must be controlled within the Box Build project.
What Must Be Revalidated When the Approved GPU Changes?
Substituting one board partner’s RTX 5090 for another can affect more than the purchase price. Before we release a revised configuration, the customer and our engineering team should confirm the items that changed.
Review area
Required input
Manufacturing consequence
Enclosure fit
Card dimensions, slot width, bracket and connector location
Confirms clearance, retention and cable routing.
Electrical interface
Power connector, PSU rating and motherboard compatibility
Confirms the released cable and power configuration.
Thermal design
Cooling layout, airflow direction and operating load
Determines whether the enclosure and fan plan need another review.
Software setup
Approved driver, firmware and operating-system image
Keeps the functional-test configuration consistent.
Acceptance test
Boot, output, load and temperature criteria agreed for the system
Defines what our production test can verify after integration.
These checks do not require BestPCBs to forecast GPU prices or recommend a retail channel. They ensure that a customer-approved change does not create a preventable assembly or test problem.
How Should GPU Availability Be Reflected in the Production Schedule?
The GPU delivery date should not automatically hold every part of the project, but the manufacturing plan must separate work that has stable inputs from work that depends on the final card. This prevents an uncertain delivery promise from becoming an unexamined Box Build completion date.
PCB and PCBA production: These stages can proceed when the electrical interfaces, board revisions and approved BOM are frozen independently of the GPU model.
Enclosure and cable preparation: Production can proceed only after the selected card’s dimensions, bracket and power-connector position are confirmed.
Final integration: The schedule should begin from the confirmed receipt of the approved GPU and completion of the agreed incoming checks.
System testing: Test time should follow installation and use the approved driver, operating-system image and acceptance criteria.
When these dependencies are visible, we can plan the surrounding manufacturing work without claiming that an unreceived GPU is available. If the approved model changes, only the affected steps need to be reviewed and rescheduled.
Who Should Supply the GPU for a Box Build Project?
Box Build procurement can use full-turnkey, partial-turnkey or consignment arrangements. For a volatile and high-value item, the appropriate model depends on who has the approved source, who accepts the quoted price and who owns the supplier warranty.
Supply model
Customer decision
Our manufacturing role
Customer supplied material
Purchase the approved GPU and retain the original supplier and warranty relationship.
Receive, record, store, kit, install and test it according to the agreed project requirements.
Customer-nominated source
Approve the exact seller, part number, price and commercial terms before purchase.
Purchase only after approval, then process the item through the agreed receiving and assembly flow.
Assembler sourcing
Approve the quoted item, validity period and any permitted alternative.
Source against the approved BOM when availability and terms can be confirmed for that order.
EBest Circuit (Best Technology) does not claim to manufacture GPUs or hold RTX 5090 inventory. Availability and warranty must be confirmed for the exact seller and order date. Our responsibility is limited to the sourcing scope accepted in the order and the manufacturing work performed on the complete assembly.
What Information Should Accompany a Customer-Supplied GPU?
Customer supplied material needs a clear manufacturing handoff. For component traceability within the Box Build record, the customer should identify the approved manufacturer part number, quantity and any serial-number mapping required for its service process.
Approved manufacturer part number and permitted revision or alternative.
Expected quantity and any project-specific serial-number requirement.
Packaging condition or handling requirement that must be checked at receipt.
Instructions for discrepancies, transit damage or a unit that fails the agreed incoming or system test.
The party responsible for supplier contact, return authorization and replacement material.
Our receiving record can document what entered the manufacturing flow and which unit was installed when serial mapping is required. It does not certify the internal authenticity of a GPU or replace the original supplier’s warranty.
What Can EBest Circuit Support Around the GPU?
At EBest Circuit (Best Technology), our relevant work is the electronics and assembly around the approved GPU. Our PCB assembly service supports SMT, through-hole and mixed assembly for control, power and interface boards. We can manufacture the project’s FR4 control and I/O PCBs, and high-Tg PCB construction is available when the board design and operating conditions justify it.
Depending on the approved project scope, we can also support component sourcing, incoming material checks, cable and enclosure integration, final assembly and agreed functional testing. SPI, AOI and X-ray apply where appropriate to the PCBA being manufactured; they should not be presented as proof of GPU authenticity. The exact Box Build test must be defined from the customer’s system requirements.
What Should Be Confirmed Before Production Release?
Before production release, the project should identify the exact GPU, supply model, expected delivery date, permitted alternatives, enclosure and power inputs, required serial records, warranty contact and system acceptance test. Once those items are agreed, we can plan the surrounding PCB, PCBA and Box Build work without treating an uncertain retail listing as confirmed production material.
For a project affected by the current GPU shortage, send the approved system BOM and assembly requirements to sales@bestpcbs.com. We will review the manufacturing scope and identify which GPU-related inputs must be supplied or approved before the order is released.
electronic glass cloth moved from a background laminate input to a visible PCB supply-chain issue in 2026. A June supplier notice reported increases of 30% for E-glass cloth and 15% for FLD2 cloth, while an August 28 notice reproduced by industry media reported a 20% adjustment for thin-cloth prepreg below 7628, versus 10% for FR-4 and the notice’s 7628-and-above prepreg group.
These figures do not mean every PCB quotation rises by the same percentage. They show where material pressure is building. The effect on a finished board depends on the laminate system, glass style, resin content, layer count, panel utilization, supplier stock, yield, order quantity, and required delivery date.
What Is Electronic Glass Cloth in a PCB?
Electronic-grade woven glass fiber fabric is made from fine glass yarn woven into a controlled cloth. Laminate manufacturers combine it with epoxy, polyimide, or another resin system to make rigid cores and prepreg. In an FR-4 construction, the woven reinforcement contributes electrical insulation, dimensional stability, heat resistance, and mechanical strength.
Several terms appear in specifications and searches. They overlap, but they are not always interchangeable:
Electronic glass cloth and electronic-grade glass fiber cloth identify the electronic-material application.
Woven glass fabric and glass fiber cloth describe the textile form more broadly.
Electronic glass fabric is a natural industry variation of the same product category.
The search phrase e glass cloth normally refers to E-glass composition, not every electronic glass material. Low-Dk or low-CTE specialty glass may use a different composition.
Searches such as glass cloth pcb, glass fabric pcb, and fiberglass cloth pcb usually point to this same reinforcement layer inside a copper-clad laminate or prepreg construction. For a broader material overview, see what copper-clad laminate is in a PCB.
Why Did Electronic Glass Cloth Prices Rise in 2026?
The reported increases were not caused by one isolated factor. Supplier and industry reports point to a combination of glass-yarn cost, energy, transportation, specialized capacity, and demand from AI servers, high-speed switches, semiconductor packages, and other advanced electronics.
The market is also segmented. Standard E-glass, low-Dk glass, low-CTE glass, spread glass, and ultra-thin glass cloth do not share the same production route or availability. A price change for one family must not be presented as a universal increase for every electronic glass product.

The August data comes from a supplier letter reproduced by financial and metals-industry media. Buyers should confirm the exact brand, grade, region, currency, order date, and open-PO treatment with their material source. Our separate Kingboard FR-4 and prepreg update explains that notice in more detail.
How Does Glass Cloth Cost Move Through the PCB Supply Chain?
The price signal passes through several commercial and manufacturing stages before it reaches a finished PCB. A glass-yarn producer supplies yarn to a weaving and treatment operation. The resulting electronic cloth is sold to a laminate manufacturer, which impregnates it with resin to make prepreg or combines it with copper foil to make CCL. A PCB factory then consumes specific core and prepreg constructions during lamination.
Pressure can change at each stage:
Glass yarn and weaving: fine-yarn availability, energy, yield, and specialist capacity affect cloth supply.
Laminate production: cloth, resin, copper foil, treatment, and coating costs are combined into a material grade.
PCB fabrication: the board’s panel area, layer count, bond plies, lamination cycles, and scrap allowance determine how much material is consumed.
Customer quotation: stock position, volume, quote validity, test scope, and delivery priority determine the final commercial effect.
This chain also explains why two suppliers may quote different changes for the same Gerber package. One may hold qualified inventory bought before the notice, while another may need to purchase new material immediately. Freight, minimum-order quantities, allocation rules, and the remaining shelf life of prepreg can also change the usable cost basis. The comparison is meaningful only when both quotations use the same stack-up, laminate series, glass construction, copper weights, acceptance criteria, quantity, and delivery basis.
Why Is Thin Glass Cloth Under More Pressure?
Thin glass cloth is not merely a lighter version of 7628. Fine yarn, weaving control, fiber opening or spreading, surface treatment, uniform resin impregnation, and thickness tolerance all influence its suitability for electronic laminates. These requirements can limit interchangeable supply.
IPC glass-style numbers such as 106, 1080, 2116, and 7628 identify different constructions. In general, thinner styles support thinner dielectric openings, while 7628 is a heavier cloth. However, the final pressed thickness and electrical behavior still depend on resin content, ply count, resin system, and the laminate manufacturer’s construction. The August notice’s “below 7628” classification is a commercial grouping in that notice, not a complete engineering rule for every supplier.
Which PCB Types May Feel the Impact First?
Boards that use more specialized, thinner, or tightly controlled dielectric constructions are more exposed to availability and substitution risk:
HDI PCB: thin dielectric build-up layers and microvia reliability depend on a controlled material system.
High-layer-count PCB: many bond plies amplify the effect of prepreg availability, press planning, and material qualification.
Thin PCB: the overall thickness budget leaves less room to replace one glass style with a thicker construction.
High-speed PCB: Dk, Df, resin content, glass weave, and trace geometry must remain aligned with the impedance and loss model.
Not every board in these categories uses the same cloth. For example, a high-speed design may require low-Dk glass rather than standard E-glass. A high-speed PCB design therefore needs material review before any cost-driven stack-up change.
Does a 20% PP Increase Mean a 20% PCB Price Increase?
No. The reported percentage applies to a material category under a supplier notice. A finished PCB quotation includes many other inputs and operations. The actual effect varies with:
board area, panel utilization, layer count, and bond-ply count;
laminate brand, material family, glass style, resin content, and copper weight;
drilling, lamination cycles, plating, surface finish, testing, and expected yield;
supplier inventory, order quantity, quote validity, and requested lead time.
A small standard double-sided FR-4 board and a 24-layer controlled-impedance board will not absorb the same material-cost change. The more useful question is which line items and stack-up layers changed, not whether one headline percentage can be copied into the finished-board price.
Can a Cheaper Glass Style Be Substituted Safely?
Only after engineering review. Two constructions with similar nominal thickness can have different resin content, Dk, Df, local weave behavior, copper geometry, and lamination performance. A substitution can change impedance, insertion loss, skew, CAF risk, drill behavior, and reliability.
Before approving an alternative, compare at least:
laminate and prepreg manufacturer, series, and approved glass style;
nominal and pressed dielectric thickness, resin content, and ply count;
Dk and Df at the relevant frequency and test method;
Tg, Td, CTE, moisture performance, and CAF requirements;
controlled-impedance geometry and simulation or coupon acceptance criteria.
This is especially important for fine-feature designs. Our UHDI printed circuit board guide shows why material and stack-up decisions must follow the actual geometry and reliability target.
How Can PCB Buyers Reduce Cost and Lead-Time Risk?
Procurement and engineering teams can act before a shortage becomes a schedule problem:
Freeze the electrical and mechanical stack-up early enough for material confirmation.
Separate mandatory material properties from brand preferences that may allow an approved equivalent.
Share realistic prototype and production forecasts so uncommon glass styles can be planned.
Ask whether the quotation is based on current inventory, a new material purchase, or an allocation.
Keep quote validity, open-PO treatment, and delivery assumptions in writing.
Never approve a high-speed or HDI substitution from a price table alone.
FAQ About Electronic Glass Cloth
Is electronic glass cloth the same as fiberglass?
It is a fiberglass textile made for electronic-material use, but the electronic-grade designation adds controls for yarn, weave, thickness, treatment, and performance. General-purpose fiberglass fabric should not be treated as PCB laminate reinforcement.
Is all PCB glass cloth E-glass?
No. E-glass is common, but low-Dk, low-CTE, and other specialty glass compositions are also used. The required material depends on the laminate family and electrical or mechanical target.
Why does glass style matter to impedance?
Glass style changes the resin-to-glass ratio and local dielectric distribution. Together with pressed thickness and copper geometry, those changes affect the impedance and loss model.
Should buyers reserve thin prepreg earlier?
For HDI, high-layer-count, thin, or high-speed designs, early confirmation is sensible when the stack-up relies on a specific glass style or laminate series. The need depends on actual supplier stock and order timing.
How Can EBest Circuit Support Your PCB Material Review?
At EBest Circuit, we review PCB fabrication requirements together with the stack-up, material system, copper weights, impedance targets, quantity, and delivery plan. If a preferred material is under price or supply pressure, we can identify which requirements are fixed and which alternatives still need technical approval.
For a project affected by electronic glass cloth availability, send your Gerber files, stack-up, material brand or grade, board thickness, copper weights, impedance requirements, order quantity, and target delivery date to sales@bestpcbs.com. We will review the material basis before confirming a quotation or proposing a substitution.
The latest Kingboard price increase concerns the materials used to manufacture PCBs, not an automatic increase in every finished-board quotation. An August 28, 2026 notice reproduced by financial media reports higher FR-4 and prepreg prices for newly accepted orders. For purchasing teams, the next step is to identify the material used in each board and confirm which commercial terms apply.
At EBest Circuit, we help customers review PCB material requirements alongside fabrication needs. This update explains the reported changes, where they enter a multilayer board’s material bill, and what to clarify when a supplier sends a revised quotation.
What Changed in the August 28 Notice?
Gelonghui’s August 28 report, carried by Sina Finance, reproduces a notice from Guangdong Kingboard Laminates Trading Co., Ltd. The stated adjustments are:
Material category in the notice
Reported increase
FR-4, all thicknesses
10%
Prepreg: 7628 and the notice’s thicker-cloth category
10%
Prepreg: the notice’s thin-cloth category below 7628
20%
The reproduced letter is dated August 28. We checked its wording against the report, but it was obtained through a media publication, not a direct supplier communication. Confirm the applicable grade and price with your material supplier before changing a purchase order.
When Does the New Pricing Apply?
The notice refers to new orders accepted from its issue date. It does not establish how every distributor will handle existing inventory, previously accepted orders, or an earlier quotation that remains valid.
Before approving a revised board price, ask for three specific confirmations:
Order status: Was the material order already accepted, or does the job still require a new purchase?
Quotation basis: Which material grade, copper weight, sheet size, quantity, currency, and tax basis are being compared?
Validity: How long does the revised quotation remain open, and what event fixes the price?
A finished-PCB purchase order and a laminate manufacturer’s order are different transactions. Do not assume that sending a board PO earlier automatically secures an earlier material price; obtain written confirmation from the party supplying your boards.
Why Are Glass Cloth and Copper Foil Important?
The letter cites rising prices and tighter supply of glass cloth and copper foil. Both are inputs to PCB laminate production; neither is simply an optional accessory that can be removed from a drawing.
A copper-clad laminate combines a dielectric base with copper foil. Prepreg supplies resin-bearing reinforcement between layers during lamination. Their costs enter the material bill through different purchased items and constructions.
The notice alone does not tell us how much either input has risen across the entire market, how long supply pressure will last, or which next adjustment will follow. Those would require separate dated evidence. For a current order, the relevant information is the supplier’s quotation for the exact material being purchased.
PCB Prepreg vs Core: Which Material Is Affected?
The distinction in PCB prepreg vs core matters because a multilayer stackup uses cured laminate and bonding sheets differently. A core is already cured; prepreg starts as resin-impregnated reinforcement that bonds the assembly during pressing.
For background on the bonding stage, see our explanation of prepreg in PCB manufacturing. For this price review, identify the actual core and prepreg entries in the approved stackup rather than treating the entire board as a single sheet of FR-4.
When comparing prepreg PCB material, retain the manufacturer’s grade, resin system, glass style, resin content, and number of plies. Two options described simply as “FR-4 prepreg” may not have the same electrical properties or processing behavior. A purchasing description that omits these details can hide a construction change inside an apparently cheaper quotation.
Why Does Prepreg PCB Thickness Need a Construction Check?
Prepreg PCB thickness is not determined by a glass-style number alone. Resin content, the selected construction, and the pressed assembly all matter. Manufacturer data can list more than one thickness or resin-content option for the same glass style.
The notice’s wording around 7628 is a supplier pricing category. It should not be converted into a universal rule that every glass-style code with a smaller numerical value is physically thinner. Match each ordered prepreg item to the supplier’s classification.
Construction also affects PCB prepreg dielectric constant. Isola’s laminate-manufacturing guide explains that glass construction and retained resin content influence dielectric properties. Its material data illustrate why an apparently similar glass designation is not enough to prove equivalence; those Isola values should not be copied into a Kingboard design.
For an impedance-controlled board, changing dielectric spacing or material properties can require a new impedance calculation and an approved stackup revision. Keep the electrical requirement fixed while evaluating the material choice.
Does a 20% Prepreg Increase Mean a 20% PCB Price Increase?
No. A percentage applied to one purchased material does not automatically apply to the total selling price of a finished PCB. The board also includes other materials, fabrication operations, inspection, testing, handling, and commercial terms.
A useful calculation starts with the affected material lines, not the total board invoice: multiply each old material-line cost by its applicable adjustment, then add the differences. That estimates the change in those lines only, assuming the same specification, quantity, and purchasing basis.
It still does not determine the final commercial quotation. Inventory purchased at an earlier price, panel utilization, production volume, and other cost changes may affect the outcome. Our copper-clad laminate price guide provides broader background on material-price factors.
If a revised quotation cites the Kingboard price increase, ask which material lines changed and whether the board specification stayed the same. A traceable explanation is more useful than applying a headline percentage to every item.
Which Cost-Saving Changes Need Engineering Approval?
Start with options that preserve the approved design, such as reviewing order quantities or panel utilization with the fabricator. Material substitutions require a separate technical decision; a lower material price does not establish that the replacement will work.
Changing prepreg construction: Review finished dielectric spacing, resin availability around copper features, and electrical requirements.
Changing laminate grade: Compare the relevant thermal and electrical properties and any material restrictions on the drawing.
Reducing copper: Recheck current handling, thermal behavior, and fabrication requirements rather than treating copper weight as a purchasing-only choice.
Changing a qualified build: Agree on required samples, inspection, and customer approval before production release.
Keep the existing approved construction if equivalence has not been demonstrated or the customer does not permit substitutions. Requalification time and scrap risk can outweigh a small purchase-price saving.
How Can We Help You Review a Material-Cost Change?
At EBest Circuit, we provide PCB fabrication and PCBA services with technical support for material and build requirements. We can review your approved stackup and discuss which material choices are fixed, which alternatives may be evaluated, and what information is needed for a current quotation.
Send your Gerber files, stackup, specified laminate grade, copper weight, order quantity, and required delivery date to sales@bestpcbs.com. If you are comparing a revised quote, include the earlier specification and quote date so we can compare the same build. Any proposed material change should be documented and approved before manufacturing.
The Panasonic laminate price increase announced on August 6, 2026 takes effect for September 1 shipments on an ex-factory basis. This August 31 update is an execution reminder, not a new price announcement. The change covers several circuit-board material categories, with different rates for general glass-epoxy and low-loss products.
For PCB buyers, the practical questions are which material their approved build uses, when that material ships, and whether a revised quotation still describes the same board. At EBest Circuit, we can review those technical requirements with you before a proposed substitution changes the build.
Which Panasonic PCB Materials Are Included?
Panasonic Industry’s official notice lists the following changes from current material prices:
Material group
Affected products
Increase
General multilayer glass epoxy
Laminate and prepreg
30%
MEGTRON / XPEDION
Laminate and prepreg
15%
LEXCM GX substrate materials
Laminate and prepreg
30%
CEM-3
Glass-composite materials
30%
FCCL
Flexible circuit-board materials
15%
These are Panasonic PCB materials, not replacement control boards for air conditioners or other appliances. Package-substrate materials, flexible materials, and ordinary rigid-board materials should also remain separate entries in a purchasing review. A rate for one category should not be applied to another simply because both are used somewhere in electronics manufacturing.
When Does the September Revision Take Effect?
The stated trigger is shipment from the factory from September 1, 2026. It is not described as a deadline based only on when a customer submits a purchase order.
For a board buyer, the laminate shipment date, PCB production start, and finished-board delivery date are three different milestones. Ask the fabricator which material transaction applies to your order rather than inferring it from your requested PCB delivery date.
Material already allocated: Confirm the allocation, quantity, and applicable quotation in writing.
Material still to be purchased: Obtain a current quote and an expected material shipment date.
Repeat orders or scheduled releases: Check whether each release has its own purchasing and pricing conditions.
A quotation’s validity period is not the same as a stock reservation. If the supplier cannot confirm allocation, do not treat material availability or an earlier price as secured.
Why Is Panasonic Revising Material Prices?
Panasonic cites sustained increases in principal raw materials, together with elevated auxiliary-material, energy, logistics, and other costs. The notice presents the revision as necessary to support continued supply.
That explanation does not provide a PCB-fabricator cost breakdown. A board quotation includes more than the purchased laminate and bonding sheets. The affected material share, processing route, quantities, and contractual terms must be reviewed for the specific order; no finished-PCB price increase can be calculated from the announcement alone.
Nor does a price notice establish that every material grade is unavailable. Treat price, stock allocation, and lead time as separate questions. A higher price is not proof of an earlier delivery slot, and an available sample sheet is not proof of production-volume availability.
What Does This Mean for Panasonic MEGTRON 6 and 7?
Panasonic MEGTRON 6 and Panasonic MEGTRON 7 are material families used in high-performance multilayer boards. They should be identified by the exact laminate and prepreg grades on the approved stackup, not just the family name.
A common percentage adjustment does not make two grades equal in absolute price or technically interchangeable. Their earlier prices, constructions, and processing requirements can differ. A purchasing comparison must retain the grade suffix, copper foil, dielectric construction, panel requirements, and order volume.
For high-speed designs, changing the dielectric system is a signal-integrity decision as well as a cost decision. Channel loss and impedance depend on the board construction and routing, not on the material trade name alone. Our high-speed PCB design guidance explains why the full interconnect needs attention.
If the drawing explicitly specifies a manufacturer and grade, keep that requirement in the quote. Present any alternative as a separate option requiring approval, not as an equivalent silently substituted during purchasing.
What Should You Check in a Panasonic MEGTRON 6 Datasheet?
A Panasonic MEGTRON 6 datasheet is useful for confirming which product a quotation actually refers to. The manufacturer’s documentation distinguishes laminate variants such as R-5775(N), R-5775(K), and R-5775(G), with corresponding R-5670 prepregs. It also identifies typical values and the conditions used to measure them.
Exact product: Match the complete grade and suffix, including the associated prepreg.
Electrical data: Compare Dk and Df only with their frequency, method, and sample conditions stated.
Thermal data: Check that the property and test method match the assembly requirement being evaluated.
Copper and construction: Retain the specified foil and dielectric details when comparing transmission performance.
Do not take a typical datasheet result as a guaranteed acceptance limit for every finished board. Define the relevant build and inspection requirements separately. For the role of the bonding material, our PCB prepreg overview provides a useful starting point.
Can a Different Laminate Reduce Cost Without Changing Performance?
Possibly, but that requires evidence for the actual design. A material with a lower quoted sheet price can still require a stackup change, trace-width adjustment, process review, or additional qualification.
Start by fixing the performance and customer requirements that cannot change. Then compare candidate materials against those requirements, estimate the work needed to approve the change, and obtain written customer acceptance before release.
Our stackup and impedance-control guidance is relevant when dielectric thickness or properties change. Price comparisons should not leave the stackup as an unspecified item to be decided after ordering.
Keeping the existing material may be the better choice when a product is already qualified, the delivery window cannot accommodate validation, or the expected saving is smaller than the change effort. The purpose of a review is to make that tradeoff visible, not to assume that a substitute is always available or worthwhile.
What Should Be Confirmed for September Deliveries?
Ask for a written order confirmation that connects the material, price, and schedule. “Material available” is too broad if the required grade, thickness, copper foil, or quantity is still unresolved.
Approved laminate and prepreg part numbers, plus any permitted alternatives.
The material allocation and expected factory shipment relevant to your job.
The quotation date, validity, and treatment of scheduled releases.
The expected PCB delivery date after material receipt and fabrication.
Who approves a material change and what validation is required.
When discussing the Panasonic laminate price increase internally, keep the supplier’s material notice separate from your project’s board quotation. That gives engineering and purchasing the same documented basis for approval.
How Can EBest Circuit Help With Your Material Review?
At EBest Circuit, we support PCB fabrication and PCBA projects, including multilayer and high-speed board requirements. We can review your specified materials and stackup, clarify which requirements must remain fixed, and discuss alternatives that may merit engineering evaluation.
Email sales@bestpcbs.com with your Gerber files, approved stackup, full laminate and prepreg grades, quantities, and target delivery date. Include any customer restrictions on substitution. We will use those requirements to discuss a current quotation and the review needed before changing the build, without treating a material-price headline as a finished-board price.
The ABF substrate shortage is becoming a high-end AI packaging constraint rather than a broad shortage affecting every substrate equally. Counterpoint Research estimated an ABF supply gap of about 10% in the second half of 2026, widening to 20% in 2027 before new capacity comes online.
The risk is concentrated in large, multilayer package substrates that consume more low-CTE glass cloth, ABF dielectric, semi-additive-process capacity, and inspection time. Buyers should qualify the exact package construction and supplier allocation instead of treating the forecast as a universal lead-time or price increase.
What Is Causing the ABF Substrate Shortage?
The shortage is being driven by rapid AI-package growth, larger substrate area, higher layer counts, constrained low-CTE T-glass, and the slow ramp of qualified high-end capacity. These pressures reduce the number of advanced packages that an existing line can produce even when the nominal panel count looks unchanged.
Counterpoint Research described a structural up-cycle tied to enterprise AI demand and estimated that one AI chip can consume roughly ten times the substrate material of a standard PC chip. That is an industry estimate, not a design rule for every package, but it explains why mix shift matters as much as unit demand.
What Is ABF Substrate Material and Film?
ABF substrate material is an organic build-up system used to route very fine connections between a high-performance semiconductor die and the larger-pitch PCB below it. ABF substrate film is the interlayer dielectric used between copper routing layers; laser processing and direct copper plating help form the dense interconnect structure.
Ajinomoto explains that ABF combines organic epoxy chemistry with inorganic microparticle filler to provide insulation, low thermal expansion, durability, and processing characteristics for advanced package substrates. The film is one part of a complete substrate that also includes copper circuitry, a core or coreless structure, vias, solder mask, surface finish, and BGA connections.
How Large Is the 2026–2027 Supply Gap?
The current public forecast points to a roughly 10% ABF gap in the second half of 2026 and a 20% gap in 2027. These figures should be treated as analyst estimates for the industry, not guaranteed shortages for every supplier, package type, or customer contract.

Why Does Low-CTE T-Glass Matter?
Low-CTE T-glass helps control dimensional stability and warpage in large, thin, multilayer organic packages. As package size and layer count increase, the substrate must survive lamination, thermal cycles, assembly, and operation while keeping fine features aligned.
Counterpoint estimated a T-glass supply-demand gap above 10% in 2026. A shortage of qualified glass cloth can restrict both ABF substrate output and high-end copper-clad laminate, even if a substrate manufacturer has available imaging, plating, and drilling equipment. An alternate glass style is not automatically interchangeable; resin compatibility, thickness, CTE, electrical properties, process behavior, and package reliability must be validated.
How Do Larger AI Packages Consume More Capacity?
Larger AI packages consume capacity through area, layer count, process steps, inspection burden, and yield—not just unit volume. More build-up layers require repeated lamination, laser-via formation, desmear, metallization, imaging, plating, etching, and inspection cycles.
More substrate area: fewer units may fit on a panel, and each defect affects more value.
More routing layers: repeated build-up cycles occupy equipment for longer.
Finer features: tighter process windows raise inspection and yield demands.
Warpage control: larger packages need more precise material and process matching.
Embedded or advanced structures: additional failure points can reduce effective output.
IBIDEN’s 2026 results presentation indexed the production load for an AI-server substrate at 1.8 times its 2024 level in 2026 and 2.5 times in 2028 when converted by semi-additive-process demand.
Which Price and Lead-Time Signals Matter?
The most useful signals are configuration-specific quotes, allocation confirmation, material status, committed capacity, qualification status, and delivery milestones. Broad market percentages do not replace a supplier’s documented production plan.

How Are ABF Substrate Manufacturers Expanding Capacity?
ABF substrate manufacturers are investing heavily, but high-end capacity takes time to install, qualify, and stabilize. IBIDEN announced an approximately JPY 500 billion investment plan for FY2026–FY2028, focused on high-performance IC package substrates for AI and high-performance servers, with sequential operation and planned mass production beginning in FY2027.
IBIDEN also stated that larger and more multilayered substrates are expected to push total semi-additive-process demand beyond industry supply capacity. Buyers should therefore distinguish a capital-spending announcement from qualified volume that is available to their exact package and schedule.
What Should Buyers Ask ABF Substrate Suppliers?
ABF substrate suppliers should answer against the exact package construction, not only a generic product family. A useful sourcing review covers materials, manufacturing site, qualified process, capacity commitment, inspection, change control, and recovery planning.
Which ABF film grade, glass style, core construction, and copper system are quoted?
Are all materials allocated for the requested prototype and production quantities?
Which site and production line are qualified for this package?
What changes require customer notification and requalification?
How are warpage, layer registration, microvias, copper thickness, continuity, and surface defects inspected?
What is the recovery plan if material or yield misses the committed milestone?
The substrate shortage can delay packaged processors before those components ever reach the PCBA line. A PCB assembler may have bare boards, passive components, and production capacity ready while waiting for the processor or accelerator package.
Project plans should link package delivery milestones to PCB fabrication, component kitting, stencil release, assembly slots, firmware readiness, and test-fixture availability. Avoid building a schedule that assumes every upstream item will arrive on the same day. The distinction between a BT substrate and a high-end ABF substrate also matters because material allocation and package applications differ.
Which Design and Qualification Actions Reduce Risk?
Risk falls when the team freezes the package interface early, keeps alternates evidence-based, and plans qualification before a shortage forces a change. Late substitutions are especially dangerous when they alter substrate dimensions, ball map, electrical behavior, warpage, thermal path, or assembly profile.
Freeze the package outline, ball map, PCB land pattern, keep-outs, and thermal interface.
Record the approved substrate construction and material set.
Qualify alternates before allocation becomes critical.
Align substrate, component, PCB, assembly, and test milestones in one schedule.
Define incoming inspection, traceability, change notification, and nonconformance handling.
FAQ About ABF Substrate Shortage
Is every ABF substrate in shortage?
No. The pressure is strongest in high-end, large, multilayer substrates for AI and advanced computing. Supplier allocation, construction, customer qualification, and contract status determine the actual risk.
What is the difference between ABF film and an ABF substrate?
ABF film is the insulating build-up dielectric. The finished substrate combines that dielectric with copper circuitry, vias, a core or coreless structure, solder mask, surface finish, and package connections.
Why does new factory capacity not solve the shortage immediately?
Equipment installation is only one step. Materials, process qualification, customer approval, yield ramp, inspection capacity, and product mix determine when usable output becomes available.
Will substrate prices rise by the same percentage for every buyer?
No. Public percentages are market estimates. The actual change depends on package size, layers, materials, committed capacity, order volume, contract terms, timing, and supplier relationship.
Can a PCB fabricator replace an ABF package substrate?
Not directly. An advanced IC package substrate uses different feature sizes, processes, materials, equipment, quality controls, and semiconductor-package qualifications from a conventional PCB.
