What Is A RF Prototype Board?
ARF Prototype Board is an initial physical circuit board created specifically for testing and validating RF circuit designs. As a physical sample during the design phase, it is used to actually measure RF performance characteristics (such as impedance matching, signal integrity, gain, and noise), verify the feasibility of high-frequency board material selection, layout, routing, and functionality, and provide a reliable basis for subsequent design iterations or mass production. Its core value lies in quickly exposing design problems at a controllable cost, ensuring that the final product meets stringent RF performance requirements.
Ensure Performance Compliance: Prototyping enables real-world testing of critical metrics (e.g., S-parameters, phase noise). By analyzing S11/S21 via vector network analyzers, engineers can pinpoint impedance mismatch issues and adjust component values (capacitors/inductors) to meet specifications like -100dBm receive sensitivity or +30dBm output power, enhancing device range and stability.
Address EMI and Thermal Challenges Early: Prototypes allow early detection of electromagnetic interference (EMI) hotspots through near-field scanning and thermal issues via infrared imaging. This facilitates rapid optimization of ground plane segmentation, shielding structures, or heat dissipation designsβreducing time and budget by over 50% compared to post-production modifications.
Accelerate Iteration and Align with Customer Needs: Physical prototypes serve as tangible validation tools for client demos or field testing. For example, in 5G small cell development, prototypes integrated into customer systems enable real-time feedback on coverage and data rates. This iterative process (3β5 cycles) ensures design alignment with market requirements, cutting time-to-market by 30% or more.
Meet Regulatory and Industry Standards: Prototyping facilitates pre-compliance testing for certifications like FCC/CE. By verifying adherence to standards (e.g., EN 300 328 for 2.4GHz devices or 47 CFR Part 15), designers can proactively adjust parameters (filter cutoff frequencies, shield dimensions) to ensure first-pass certification success, avoiding delays in product launch.
When to Use RF Prototype Board?
Applications of RF prototype board:
First-Version Verification of New RF Architectures: When implementing complex designs for the first time (e.g., millimeter-wave arrays or multi-stage LNA chains), real-world measurement of nonlinear effects and inter-stage interference is mandatory, as simulation cannot fully replicate these phenomena.
Evaluation of High-Frequency Material Transitions: When switching substrate suppliers (e.g., Rogers to Tachyon) or adopting cost-effective alternatives, prototype boards are required to quantify differences in insertion loss and phase stability.
On-Site Antenna System Matching: When antenna impedance is influenced by mechanical components or human-machine interactions, prototypes enable real-environment debugging of matching networks (e.g., compensating for 5G antenna frequency shifts caused by smartphone chassis).
Pre-Certification EMC Risk Mitigation: Prior to FCC/CE submission, prototypes are used for self-testing radiation spectra to identify issues like clock harmonics or switching noise coupling, preventing certification failures that delay projects.
Production Process Limit Testing: When evaluating risky processes such as low-cost FR4 hybrid high-frequency materials or ultra-fine-pitch BGA soldering, prototypes validate mass production feasibility (e.g., tolerance of 77GHz microstrip lines in automotive radar).
Multi-Board System Integration Debugging: When integrating RF subsystems (e.g., FEM + transceiver chips) with digital boards, prototypes expose cross-board ground bounce and crosstalk issues often overlooked in simulation models due to connector parasitics.
Customer Acceptance Prototype Delivery: For customers requiring advance validation of hardware metrics (e.g., contractual PA efficiency requirements for base station OEMs), prototype boards serve as the sole legally binding deliverable.
1. Material Selection: Choose low dielectric constant (Dk) and low loss (Df) substrates (e.g., Rogers RO4000, PTFE ceramic composites). Use reversed copper foil to reduce high-frequency skin effect.
2. Panel Cutting: Cut 1020mmΓ1020mm copper-clad laminates to design dimensions, optimizing panel size to improve material utilization (e.g., n-division cutting of raw materials) and reduce waste edge costs.
3. Drilling and Hole Metallization: Perform high-precision CNC drilling for through-holes/blind holes with hole diameter tolerance β€Β±0.1mil. PTFE materials require plasma desmear treatment. Use chemical copper plating + electroplating thickening to ensure hole wall copper thickness β₯20ΞΌm for interlayer electrical connectivity.
4. Imaging and Etching: Adopt LDI (Laser Direct Imaging) technology to precisely replicate circuit patterns via high-energy UV laser scanning of photoresist dry film, achieving line width tolerance Β±0.1mil. Remove non-circuit copper with acidic/alkaline etching solutions, combined with side-etch control to maintain impedance consistency (deviation β€Β±5%). Validate via AOI/AVI for line width deviation and copper residue defects.
5. Lamination and Pressing: For multilayer boards, use symmetric stack-up structures (e.g., 3+3 layers) pressed at 180β/300PSI to prevent warpage. High-layer-count boards employ stepped pressing for staged stacking to ensure uniform interlayer bonding. After outer layer circuit completion, apply solder mask (green oil) printing and silkscreen marking, forming protective layers via exposure and development.
6. Surface Finish and Profiling: Surface finishes include ENIG, HASL (Hot Air Solder Leveling), OSP, etc. Gold fingers are plated with hard gold for wear resistance. Use CNC routing/V-scoring for precise board separation, with rounded corners/edge grinding for smooth edges.
7. Electrical Performance Testing: Conduct flying probe tests/test fixtures to detect open/short defects. Use four-wire low-resistance testing for precise low-resistance measurement. Validate impedance consistency (deviation β€Β±10%) via TDR (Time Domain Reflectometry) and measure S-parameters (insertion loss, return loss) with VNA (Vector Network Analyzer) to ensure RF performance compliance.
8. Environmental Reliability Testing: Verify material stability through thermal cycling tests and assess extreme environment adaptability via thermal shock tests. Use microsection inspection to check hole wall copper thickness and interlayer alignment accuracy (error β€5ΞΌm), ensuring no delamination or warpage defects.
9. Visual and Functional Inspection: Identify circuit defects via AOI (Automated Optical Inspection) and assist manual inspection with AVI (Automated Visual Inspection) systems. Conduct FQA (Final Quality Audit) to ensure flawless appearance. Perform 100% electrical testing across all test points to eliminate functional defect leakage.
10. Sample Delivery and Validation: Execute final inspection before delivery, with ESD (Electrostatic Discharge)-compliant packaging and attached test reports/process specifications. Customers conduct soldering tests and signal integrity validation post-receipt, providing feedback for design iterations (e.g., trace width adjustment, layout optimization).

What is a PCB Footprint?
In PCB design, a footprint is the physical representation of an electronic component on the board layout. Think of it as a “footprint” left by the component. It does not define the electrical function but rather the physical connection points and keep-out areas.
βKey Elements of a Footprint:ββ
βPads:ββ These are the copper areas where the component’s leads or terminals are soldered. They can be for through-hole (pads with holes) or surface-mount technology (SMT).
βSolder Mask Opening:ββ This is an opening in the solder mask layer that exposes the copper pad, allowing for soldering. The opening is typically slightly larger than the pad.
βSilkscreen Outline:ββ This is a non-conductive drawing on the board that shows the approximate shape and orientation of the component, aiding in assembly and debugging.
βCourtyard:ββ This is a keep-out area that defines the space required for the component itself, ensuring no other parts are placed too close.
βReference Designator:ββ The unique identifier (e.g., R1, C5, U3) that links the footprint to its schematic symbol.
βImportance of Accuracy:ββ An incorrect βPCB footprintβ is a primary cause of manufacturing defects. A pad that is too small can lead to a weak solder joint; a pad that is too large can cause solder bridging. Accurate βfootprint designβ is the first step toward βfast turn PCB fabrication.
What is the Carbon Footprint of a PCB?
While “PCB footprint” primarily refers to the land pattern, the term “carbon footprint” relates to the environmental impact of manufacturing a PCB.

What is 12 Layer PCB fabrication? This guide details its applications, fabrication process, our specialized services, capabilities and how to get a quote.
Are you troubled with these problems?
How to solve signal crosstalk and delay issues in dense 12-layer PCB routing?
With multiple layers and challenging PCB material expansion control, how to ensure interlayer alignment accuracy?
Can quality and efficiency be balanced given long prototype cycles and cost pressures?
As a 12 layer PCB fabrication manufacturer, Best Technology can provide you service and solutions:
Precise Stack-Up Design + Signal Integrity Simulation: Utilizing proprietary impedance calculation models and EMC simulation tools to preemptively mitigate high-frequency signal distortion risks, ensuring clean, interference-free critical signal paths.
Smart Lamination Process + Laser Positioning System: Adopting TG170 high-stability substrates paired with real-time temperature-pressure monitoring and X-ray hole calibration, achieving β€50ΞΌm layer misalignment tolerance to overcome high-layer alignment challenges.
Flexible Production Line + Tiered Pricing Strategy: Establishing a rapid prototyping line for 5-7 day prototype delivery; implementing “step-down pricing” for small-to-medium batches to reduce upfront investment costs.
12 layer PCB fabrication refers to the process of producing printed circuit boards with 12 layers of conductive copper foil circuit patterns. These layers (including signal layers, power layers, and ground layers) are interconnected through precision lamination and plated copper vias (PTH) to form complex, high-density circuit channels. This multilayer structure is designed for complex electronic devices that require extremely high performance, high-speed signal integrity, strict power distribution, and electromagnetic compatibility (EMC). The manufacturing process involves precise interlayer alignment, drilling, electroplating, and stringent control, making it significantly more technically challenging and costly than low-layer PCBs.
Communication equipment: such as 5G base stations, high-speed routers, switches, and satellite communication equipment, requires processing high-frequency signals and ensuring signal integrity.
High-performance computing: servers, data center equipment, and artificial intelligence hardware need to support multi-processor collaboration and high-speed data transmission.
Medical electronics: CT scanners, monitoring equipment, and medical imaging systems require high reliability and interference immunity.
Automotive electronics: Advanced Driver Assistance Systems (ADAS), in-vehicle infotainment, and engine control units need to meet stringent environmental stability standards.
Industrial automation: industrial controllers, robotic systems, and precision instruments need to implement multi-channel signal control and power management.
Aerospace and defense: avionics equipment, radar systems, and military communication hardware require resistance to extreme environments and long-term reliability.
12 Layer PCB Fabrication Process
1. Stackup Design
Signal-Power-Ground Coordination Design: Adhere to three principles: signal layers adjacent to ground layers, power layers partitioned and isolated, and impedance accurately matched. Typical 12-layer structures use “signal-ground-power-ground” repeating units. High-frequency signal layers (e.g., β₯25Gbps) should be sandwiched between two ground layers (stripline structure) with spacing β€0.5mm to suppress crosstalk below -40dB. Power layers are partitioned by voltage domains (e.g., 3.3V/1.8V/0.9V) with β₯0.5mm ground isolation bands to reduce power ripple coupling by 50%.
Layer Thickness Balance and Symmetry Control: Top/bottom layer base material thickness and copper foil weight must be strictly symmetric (e.g., 1oz copper + 0.2mm base for outer layers, 0.5oz copper + 0.15mm base for inner layers). Total thickness is controlled at 2.0Β±0.1mm with warpage β€0.75% to avoid connector insertion issues or mechanical strength degradation.
EMC Optimization Design: Minimize differential/common-mode radiation through “signal layer adjacent to reference planes” and “tight coupling between power and ground planes”. For example, a 12-layer board can allocate 6 signal layers and 6 reference planes, ensuring high-frequency signals reference the same plane during layer transitions to reduce cross-partition phenomena.
2. Inner Layer Core Board Production
Pattern Transfer Precision Control: Utilize laser direct imaging (LDI) technology with exposure energy accuracy Β±50mJ/cmΒ² and line width/spacing accuracy β€75ΞΌm. After cleaning, copper-clad laminates are coated with photosensitive film. UV light solidifies transparent regions, while unexposed areas are stripped using alkaline solutions (e.g., NaOH). Post-etching micro-etching enhances surface roughness to Ra 0.8-1.2ΞΌm for improved interlayer bonding.
Black Oxide/Brown Oxide Treatment: Inner layer copper surfaces undergo chemical oxidation to form micro-porous structures (1-2ΞΌm thick), ensuring no delamination risk during lamination and enhancing adhesion for subsequent hole metallization.
3. Lamination Process
Precision Temperature-Pressure Control: In vacuum environments, segmented pressure application is used: 5-15 minutes of pre-pressing to expel air bubbles, followed by 30-60 minutes of full-pressure curing at 180-220Β°C and 200-400psi pressure. Heating rates are controlled at 2-5Β°C/min to prevent thermal stress-induced delamination or warpage. Prepreg (PP) melts and flows during curing, forming the multilayer substrate with interlayer alignment accuracy β€Β±50ΞΌm.
Material Compatibility Verification: Base material CTE (coefficient of thermal expansion) must match adhesive properties. Cleanliness is maintained below Class 1000 with humidity at 40-60%RH to avoid moisture absorption affecting interlayer bonding.
4. Drilling and Hole Metallization
High-Precision Drilling Technology: Mechanical drilling covers diameters of 0.1-0.3mm at speeds of 100-200kRPM, feed rates of 0.5-1.5mm/s, and coolant flows of 500-1000mL/min, achieving hole wall roughness β€20ΞΌm. Laser drilling (COβ/Nd:YAG) for blind/buried holes supports diameters as small as 50ΞΌm, requiring controlled carbon residue removal via plasma etching or chemical cleaning to ensure clean hole walls.
Hole Metallization Quality Control: Chemical copper plating begins with a 1ΞΌm conductive layer, thickened to 25ΞΌm via electroplating with thickness uniformity β€Β±10%. Reliability is validated through thermal shock tests (-40Β°C to 125Β°C for 1000 cycles) to prevent copper layer peeling or fracture.
5. Outer Layer Circuit Production
Pattern Transfer and Etching: Positive film processes transfer outer layer circuits. Exposure energy ranges from 600-800mJ/cmΒ², developer concentration is 1.2%, and development time is 60-90 seconds for precise window dimensions (e.g., 0.1mm window deviation β€Β±0.02mm). Post-etching tin stripping preserves copper traces with line width/spacing accuracy Β±5%.
Process Comparison and Selection: Hot air solder leveling (HAL) offers low cost but higher surface roughness; OSP is simple but has a storage life β€3 months. Electroless nickel/immersion gold (ENIG) suits fine-pitch leads with excellent durability; immersion silver/tin suits high-frequency applications but requires moisture and electronic migration protection.
7. Electrical Testing and Reliability Verification
Full-Link Testing Standards: Flying probe tests detect opens/shorts with impedance accuracy Β±10%; fixture tests validate functional connectivity. Reliability tests include thermal shock (-40Β°C to 125Β°C for 500 cycles), thermal cycling (-55Β°C to 125Β°C for 1000 cycles), humid heat aging (85Β°C/85%RH for 168 hours), and vibration tests (random vibration 20G). Hole pull strength β₯10N and peel strength β₯1.0N/mm are ensured.
Comprehensive Quality Inspection: Visual checks assess pad integrity and solder mask defects (e.g., bubbles/pinholes); dimensional measurements maintain Β±0.1mm accuracy. Packaging uses anti-static bags + corrugated boxes with moisture/vibration protection, compliant with IPC-A-600 standards for damage-free transport.
Environmental Sustainability: Wastewater undergoes “physical-chemical + biochemical + membrane filtration” tertiary treatment with reuse rate β₯70%.

βEnhanced Performance:ββ Dedicated power and ground planes improve power integrity, reduce EMI, and allow for controlled impedance routing, which is vital for high-speed digital and βmultilayer RF PCB design.
βImproved Reliability:ββ A well-planned multilayer board is generally more robust than a double-sided board, with better resistance to environmental factors and physical stress due to a more balanced structure.
In summary, βmultilayer PCB designingβ is not just an option but a necessity for modern electronics, enabling the advanced features and miniaturization that consumers demand. Partnering with an expert is key to unlocking these benefits.
βHow to Design Multilayer PCB?ββ
The βmultilayer PCB design processβ is a structured sequence of critical steps that balances electrical performance, manufacturability, and cost. Following a proven methodology, as detailed in expert resources, is the difference between success and failure. This process involves strategic planning from layer stack-up to final validation.
β1. Define Requirements and Schematic Captureβ Start by finalizing the schematic and defining system requirements. This foundational stage directly influences all subsequent decisions.
βDetermine Board Specifications:ββ Analyze the circuit’s scale, board size, and critical performance requirements, especially Electromagnetic Compatibility (EMC).
βAssess Wiring Density:ββ Use EDA tools after component pre-layout to analyze potential routing bottlenecks. This assessment helps in estimating the necessary number of signal layers.
βIdentify Critical Signals:ββ Classify special signals such as high-speed lines, differential pairs, and sensitive analog lines. Their quantity and requirements are key factors in deciding the layer count and stack-up strategy.
β2. Plan the Layer Stack-up β This is a foundational step where the PCB’s performance is largely determined. The goal is to determine the number of layers, their function (signal, power, ground), sequence, and material thickness.
βDetermine Layer Count:ββ Balance routing needs against cost and manufacturing complexity. The number of power domains and grounding requirements will determine the number of internal planes.
βAdhere to Key Stack-up Principles:ββ
βShielding:ββ Each signal layer should be adjacent to an internal power or ground plane (e.g., Top-Layer next to GND plane) to use the copper layer as a shield.
βPower-Ground Coupling:ββ The core internal power and ground layers should be tightly coupled by using a thin dielectric thickness between them. This improves decoupling and increases resonant frequency.
βHigh-Speed Signal Isolation:ββ High-speed signal layers should be embedded between two internal planes (e.g., Signal layer between GND and POWER), which confines EMI and provides shielding.
βAvoid Adjacent Signal Layers:ββ Prevent two signal layers from being directly adjacent to minimize crosstalk. If unavoidable, add a ground plane between them.
βSymmetry:ββ Maintain a symmetrical layer stack-up to prevent board warping during manufacturing.
βSelect an Optimal Configuration:ββ Based on the principles above, choose a standard stack-up. For example, a preferred 4-layer stack is: βTop (Signal) -> GND (Inner 1) -> POWER (Inner 2) -> Bottom (Signal)β. A preferred 6-layer stack is: βTop (Signal) -> GND (Inner 1) -> Signal (Inner 2) -> POWER (Inner 3) -> GND (Inner 4) -> Bottom (Signal)β. These configurations provide excellent shielding and tight power-ground coupling. The stack-up is defined using the EDA software’s βLayer Stack Manager.
β3. Component Placement with DFM and Modularityβ Place critical components first, considering signal flow, thermal management, and most importantly, Design for Manufacturability (DFM).
βModular by Power Domain:ββ Group components that share the same power supply and ground type together. This simplifies the later task of βinternal plane segmentation.
βPrioritize Interface and High-Noise Components:ββ Place connectors on the board edges for easy access. Position noisy components (e.g., clock generators, switching regulators) close to their target components (like a CPU) but away from sensitive analog circuits.
βConsider Manufacturing:ββ Prefer single-sided component placement. If double-sided, place only surface-mount devices (SMDs) on the bottom layer. Ensure adequate spacing for automated assembly and soldering.
βImplement Decoupling:ββ Place decoupling capacitors (e.g., 0.1Β΅F) close to the power pins of ICs. Larger filter capacitors (e.g., 10Β΅F) should be placed near power entry points.
β4. Routing and Critical Net Prioritizationβ Route signals based on priority, adhering to strict rules for spacing and impedance.
βRoute by Priority:ββ Route high-speed clocks, differential pairs, and sensitive analog signals first, ensuring they have continuous reference planes and meet impedance constraints.
βFollow General Routing Rules:ββ
βTrace Width:ββ Calculate width based on current. A general rule is 1A per 1mm of trace width (for 0.05mm copper thickness). Power and ground traces should be wider (β₯50mil).
βSpacing:ββ Maintain sufficient clearance between traces, especially for high-voltage differences. A common rule is 5.08V/mil for electrical insulation.
βCorners:ββ Use 45-degree angles or arcs instead of 90-degree sharp corners to avoid RF radiation and manufacturing issues.
βShielding:ββ For critical high-frequency signals, use a “guard trace” β a grounded trace that runs alongside the signal to isolate it.
βSeparate Analog and Digital Grounds:ββ Keep analog and digital grounds separate, connecting them only at a single point to prevent ground loops.
βPlan for Internal Planes:ββ Route all signal lines first. The power and ground connections will be completed through the internal planes using vias.
β5. Internal Plane Design and Segmentationβ For boards with multiple power domains, the internal power plane must be segmented into isolated regions.
βUse the Split Plane Tool:ββ In your EDA software (e.g., Altium’s βSplit Planesβ tool), define polygonal boundaries for each power net on the internal plane.
βSet Clearance Rules:ββ Define rules for βPower Plane Clearanceβ (insulation gap around non-connected vias) and βPower Plane Connect Styleβ (thermal relief connection for pins).
βKey Considerations:ββ Ensure the segmentation boundary does not pass over a pad that belongs to the same net, as this can cause connection issues.
β6. Design Rule Check (DRC) and Final Validationβ The final step is a comprehensive verification against a set of rules to ensure the design is error-free and manufacturable.
βRun a Comprehensive DRC:ββ Check against your manufacturer’s capabilities for trace width, spacing, hole sizes, and other physical constraints.
βValidate Plane Connections:ββ Ensure all power and ground pins are correctly connected to their respective planes with the appropriate style (e.g., thermal relief).
βAdd Final Touches:ββ Perform teardroping (adding tapered transitions between pads and tracks) to improve mechanical strength. Add copper pours on unused areas of signal layers and connect them to ground to shield noise.
βFinal Review:ββ Check for consistency in silkscreen labels, component orientation, and that no critical guidelines have been violated.
Ultimately, knowing βhow to design multilayer PCBβ effectively requires a disciplined approach that balances sophisticated electrical principles with practical physical manufacturability. By meticulously following these stepsβfrom strategic stack-up planning governed by βmultilayer PCB design guidelinesβ to rigorous final validationβyou can transform a complex schematic into a reliable, high-performance multilayer circuit board.

Flexible Circuit Board Assembly Manufacturing Process
1. Material Selection and Pretreatment
Select polyimide (PI) or polyester (PET) flexible substrates paired with rolled copper foil or electrolytic copper foil as conductive layers. Clean surfaces chemically to remove oil, oxides, and impurities, followed by pre-baking (80β100Β°C for 4β8 hours, up to 125Β°C in special cases) to eliminate moisture and prevent delamination during reflow. Match copper foil thickness to design requirements (e.g., 1/3 oz for ultra-fine lines) and verify dimensional stability and bending resistance.
2. Circuit Pattern Formation
Use laser direct imaging (LDI) or photolithography to transfer circuit patterns onto the substrate. Apply dry film, expose and develop to create precise graphics, then etch away excess copper with controlled etchant concentration and temperature to form high-precision conductive lines. Ensure line width/spacing meets specifications (e.g., 0.05mm for ultra-fine lines) to avoid shorts/opens, and use optical alignment for enhanced accuracy.
3. Lamination and Structural Reinforcement
Bond multiple flexible layers with adhesive films (e.g., ACF, acrylic) under high temperature (160β200Β°C) and pressure (30β60 minutes). Apply segmented pressure control (low pressure to remove air bubbles, high pressure for curing) and manage heating rates (2β5Β°C/min) to prevent thermal stress warping. Match substrate CTE to ensure interlayer alignment deviation <50ΞΌm. Validate quality via ultrasonic scanning or X-ray inspection for bubbles/delamination.
4. Drilling and Via Processing
Perform laser or mechanical drilling (diameter accuracy Β±0.05mm), then deposit conductive layers on hole walls via electroless copper/electroplating for interlayer connections. Optimize drill selection (carbide/ceramic-based), speed (avoid burning/breaking), feed rate (prevent rough walls), and use air/suction for debris removal to avoid wall scratches. Reserve buffer zones in vias to mitigate stress concentration during bending.
5. Surface Plating and Protection
Treat exposed copper lines with electroless nickel immersion gold (ENIG), organic solderability preservative (OSP), or immersion tin to enhance solderability and corrosion resistance. Control ENIG nickel thickness (3β5ΞΌm) and gold thickness (0.05β0.1ΞΌm), OSP film uniformity (0.2β0.5ΞΌm), and prevent tin whisker growth. Apply protective films (PI/PET) with smooth edges and validate adhesion via peel strength tests (>0.5N/mm).
6. Component Mounting and Soldering
Mount resistors, capacitors, ICs, etc., precisely using SMT machines (mid/high-speed) with optical MARK alignment (accuracy Β±0.05mm). Use forced convection reflow ovens with temperature profiles (peak 220β240Β°C) to manage chain stability and airflow, preventing solder bridging/beading. For laser soldering, adjust power/time parameters to ensure robust joints without thermal damage.
7. Functional Testing and Quality Inspection
Verify reliability via AOI (line defects), flying probe (continuity/insulation), bending tests (>10,000 cycles at β€5mm radius), thermal shock (-40Β°C to 125Β°C cycles), and environmental tests (85Β°C/85% RH for humidity/salt spray). Measure dimensions (outline/hole accuracy), impedance (Β±10% tolerance), and inspect solder pads for oxidation/print clarity under microscopes. Final products undergo full FQC checks to meet IPC-6013 standards, ensuring no shorts/opens/delamination.
8. Packaging and Storage
Package in anti-static bags/foam boxes to prevent compression, impact, or static interference. Store in dry (40β60% RH), ventilated, corrosion-free environments at 20Β±5Β°C to avoid moisture absorption and deformation. Secure pallets during transport to prevent component shifting.
