Fiberglass Circuit Board: Types, Features & Applications

Tuesday, April 22nd, 2025

Fiberglass circuit board is the backbone of today’s electronics. These boards support and connect components in almost every electronic device, from consumer gadgets to industrial control systems. Unlike ordinary materials, fiberglass brings strength and stability. It holds up well under heat, resists moisture, and stays firm under mechanical stress.

What Are Fiberglass Circuit Boards?

A fiberglass circuit board is a type of printed circuit board (PCB) made using a base material reinforced with glass fibers and resin—typically epoxy. This combination results in a strong, heat-resistant, and electrically stable platform used to mount and interconnect electronic components.

Also called printed circuit board fiberglass, these boards dominate the electronics industry thanks to their durability and consistent performance. From mass-produced gadgets to high-end machinery, fiberglass boards provide the structural and electrical backbone that keeps everything working smoothly.

Fiberglass Circuit Board: Types, Features & Applications

What Are Fiberglass Boards Made Of?

Fiberglass boards are made from fine strands of glass spun into a fabric. This fabric, typically known as glass cloth, is then saturated with epoxy resin. Once hardened, the composite becomes the core insulating layer in a fiberglass circuit board.

The most common material is FR4. It includes:

Woven E-glass (Electrical-grade glass): Provides electrical insulation and dimensional stability.
Epoxy resin: Bonds the glass fibers and maintains structure under thermal stress.
Copper foil: Laminated onto one or both sides to create electrical pathways.

Together, these elements create an electrical fiberglass board that is tough, heat-resistant, and non-conductive at its core.

Types of Fiberglass Circuit Boards

Fiberglass circuit boards aren’t one-size-fits-all. They come in multiple variations to meet different design and performance needs. Whether you’re designing a basic remote control or a complex radar module, there’s a fiberglass board fit for the job.

Single Layer Fiberglass Circuit Board

This is the most basic type. It has copper traces on only one side of the board. It’s often used in low-cost consumer electronics, LED lights, and household appliances. Despite its simplicity, the fiberglass circuit board structure keeps it durable and stable.

Double Layer Fiberglass Circuit Board

With copper layers on both sides and vias connecting them, this board offers more routing space and better performance. It’s a popular choice for audio equipment, industrial sensors, and power supplies. These boards balance cost with performance and are widely produced by fiberglass circuit board manufacturers worldwide.

Multilayer Fiberglass Circuit Board

These contain three or more layers of fiberglass and copper laminated together. They are essential for smartphones, routers, and advanced computing devices. With increased layer count comes better signal control and component density.

HDI Fiberglass Circuit Board

High-Density Interconnect (HDI) boards pack more functionality into smaller areas. They use microvias, blind vias, and fine lines to boost performance without increasing board size. HDI designs often use printed circuit board fiberglass materials for strength and tight tolerances.

High Frequency Fiberglass Circuit Board

For RF or microwave applications, standard fiberglass isn’t always enough. Specialized fiberglass composites with low dielectric loss are used. These boards are perfect for radar systems, antennas, and satellite communication.

Rigid-Flexible Fiberglass Circuit Board

Combining rigid fiberglass sections with flexible polyimide layers, these hybrid boards offer both structural support and flexibility. They’re widely used in wearables, military electronics, and compact medical devices.

Features of Using Fiberglass Circuit Board

Fiberglass circuit boards offer several unmatched advantages. These features help explain why they’re so common in nearly every electronic product.

Thermal Stability: Fiberglass holds up well under heat. It won’t warp or delaminate under typical operating conditions.
Dimensional Stability: Even in humid or fluctuating environments, the board keeps its shape.
Electrical Insulation: The glass fibers prevent current leakage and minimize signal loss.
Mechanical Strength: These boards don’t crack easily. They can take a beating during assembly or usage.
Low Fiberglass Board Price: Compared to ceramics or PTFE substrates, fiberglass board price is much lower—without major performance tradeoffs.

Why Is Fiberglass Used in Motherboards?

Motherboards are the nerve center of any computing device. They require a substrate that’s flat, stable, and electrically inert. Fiberglass checks all those boxes. Its woven glass core resists bending and warping over time, ensuring that pins, sockets, and solder joints stay aligned. It also helps dissipate heat generated by processors and other high-power components.

Motherboards also demand multi-layered structures. Only multilayer fiberglass circuit boards can deliver the routing density needed for complex connections between CPU, RAM, GPU, and other modules. That’s why fiberglass remains the default material for virtually all desktop and laptop motherboards.

What Is Fiberglass Board Used For?

Beyond motherboards, electrical fiberglass boards are everywhere:

Consumer Electronics: Smartphones, TVs, game consoles.
Automotive Systems: Engine controls, infotainment, safety modules.
Industrial automation: Robotics, factory controls, and power distribution.
Healthcare equipment: Monitors, diagnostic tools, and imaging devices.
Telecom Infrastructure: Routers, switches, and antennas.
Telecommunication devices: Routers, modems, and base stations.
LED Lighting: Strip lights, bulb circuits, streetlamps.
Aerospace Systems: Flight controls, navigation, radar electronics.

Thanks to their adaptability and performance, fiberglass boards can be customized for nearly any electrical task. This is why fiberglass circuit board manufacturers remain in high demand globally.

Why Is Fiberglass Hazardous?

Though highly useful, fiberglass isn’t without precautions. During manufacturing, cutting or sanding fiberglass can release microscopic glass particles. These can irritate the skin, eyes, and respiratory system. That’s why workers must wear protective gear in production settings.

However, once the board is sealed and installed, it poses minimal risk. Finished electrical fiberglass boards are stable, safe, and inert under normal use conditions. They do not emit toxins or degrade during product life.

Is Glass Fiber the Same as Fiberglass?

Technically, yes—glass fiber and fiberglass refer to the same material. “Glass fiber” usually describes the raw filament or strands. “Fiberglass” refers to the composite made from glass fibers and resin.

In PCB manufacturing, the terms are often used interchangeably. Whether you say printed circuit board fiberglass or glass fiber PCB, the meaning remains consistent: a reliable, heat-resistant circuit platform. While the terms are related, in practice, fiberglass is the final product used in PCBs, not just the raw glass fiber.

FAQs

Q1: Is fiberglass better than FR2 in circuit boards?

Yes. Fiberglass (FR4) offers higher strength, better insulation, and improved heat tolerance compared to FR2 paper-based boards.

Q2: How much does a fiberglass board cost?

The fiberglass board price varies by layer count, size, and copper thickness. Single-layer boards may cost less than $1 per piece, while multilayer HDI boards are higher.

Q3: Can fiberglass circuit boards handle high power?

Yes. With proper copper thickness and thermal management, fiberglass PCBs handle moderate to high power loads reliably.

Q4: Are fiberglass boards environmentally friendly?

Aluminum Nitride Thermal Conductivity vs. Temperature

One of the standout features of AlN is its thermal conductivity, often ranging from 160 to 180 W/m·K. However, conductivity changes with temperature.

At room temperature: ~170–180 W/m·K
At 300°C: Drops slightly to ~150 W/m·K
At 500°C: May fall to ~130 W/m·K

This predictable behavior allows engineers to model heat dissipation accurately. Unlike FR4 or alumina, AlN can handle continuous high temperatures without degrading or delaminating. Our DPC AlN ceramic PCBs at Best Technology are tested for thermal cycling, ensuring they perform reliably under dynamic load conditions—especially in EVs, telecom equipment, and military electronics.

What Is the Difference Between Ceramic Substrate and FR4?

This is a common question from design engineers and procurement teams alike. Ceramic substrates (such as aluminum nitride (AlN), alumina (Al₂O₃), and silicon nitride) and FR4 PCBs are used in very different types of applications, even though both serve as the base materials for electronic circuits. Their differences go far beyond appearance and cost—they impact performance, reliability, and product lifespan.

Here’s a detailed breakdown of the key differences between ceramic substrates and FR4 PCBs:

Feature	Ceramic Substrate (AlN, Al₂O₃, Si₃N₄)	FR4 PCB
Thermal Conductivity	Very high (AlN: 170–180 W/m·K, Al₂O₃: 20–30 W/m·K)	Low (~0.3–0.4 W/m·K)
Electrical Insulation	Excellent (ideal for high-voltage applications)	Good, but breaks down at high heat
Heat Resistance	Can operate >500°C	Limited to ~130–150°C continuous
Dielectric Constant (High Frequency)	Stable, low-loss	Less stable, higher losses at GHz
Coefficient of Thermal Expansion (CTE)	Matches semiconductor materials like silicon	Higher, may cause stress and delamination

Our team evaluates your thermal and electrical needs to recommend the optimal ceramic board thickness.

What Is an Alternative to Aluminum Nitride?

While AlN is powerful, it’s not always the default choice for every budget or function. Alternatives include:

Alumina (Al₂O₃): Lower cost, but only 20–30 W/m·K thermal conductivity
Silicon nitride (Si3N4) substrate: Good thermal and superior mechanical strength
Beryllium oxide (BeO): High thermal performance, but health concerns during processing

Of these, silicon nitride stands out as the closest functional competitor. It’s mechanically superior but falls behind in thermal conductivity. In many cases, choosing between the two comes down to application specifics—space, vibration, power load, and cost.

AlN Ceramic Substrate vs. Silicon Nitride Substrate

Let’s take a closer look at how AlN and silicon nitride compare:

Property	AlN Ceramic Substrate	Silicon Nitride Substrate
Thermal Conductivity	170–180 W/m·K	70–90 W/m·K
Mechanical Toughness	Good	Excellent
Electrical Insulation	High	Moderate
Dielectric Strength	High	Moderate
CTE Match with Silicon	Close	Slightly higher
Weight	Lighter	Heavier

In high-vibration environments such as engine control units, silicon nitride is a strong choice. But in RF, LED, or power modules, AlN ceramic boards are the go-to for managing heat and electrical insulation.

What is PCB Heat Sink Pad? How to Design a Thermal Relief Pad?

Monday, April 21st, 2025

What is PCB Heat Sink Pad?

In high-power electronics, heat is a persistent issue. When left unmanaged, it leads to failure, reduced life span, or poor performance. One of the smart ways to address this is by using a PCB heat sink pad. Sometimes referred to as thermal relief pads, these are conductive areas on a printed circuit board that channel heat away from components. They play a critical role in thermal management, especially in compact and high-density board layouts.

These pads are often seen near power components, processors, or any part prone to heat buildup. By connecting to thermal vias or copper pours, they guide excess heat to ground or large copper areas. Thermal pads improve overall stability without the need for bulky external coolers. A well-designed thermal pad saves cost, space, and ensures better thermal cycling performance.

Importance of PCB Heat Sink Pad

The importance of a PCB heat sink pad lies in its ability to support both thermal and electrical performance. As devices get smaller and more complex, the demand for thermal balance grows. Traditional cooling methods, like fans or heatsinks, aren’t always viable in a tight layout. That’s where these pads step in.

They serve as an internal heat escape path. By reducing the junction temperature of critical parts, the heat sink pad ensures devices function at optimal levels. Without it, hot spots develop, possibly leading to delamination or component drift. In automotive, aerospace, or industrial environments, this can’t be ignored.

Another key advantage is manufacturing. During reflow soldering, thermal pads help maintain consistent heating. This improves solder joint quality, avoiding cold joints or solder bridges.

What Is the Function of a PCB Heat Sink Pad?

The core function of a PCB heat sink pad is to pull heat away from the component body. This prevents overheating and promotes reliability. A pad usually sits beneath a hot-running device and connects to a ground or power plane through thermal vias. These vias act like vertical pipes that carry heat down to larger copper surfaces.

Besides thermal performance, the pad also serves mechanical purposes. It supports the component body, helps with proper alignment during placement, and aids in reflow stability. In power ICs, LEDs, and RF modules, such a pad is more than a convenience—it’s a necessity.

Often placed under QFNs, D-Pak, or Power MOSFETs, thermal pads are essential for packages where direct contact to the PCB is required for heat dissipation.

PCB Thermal Pad vs Heatsink

Understanding the thermal pad vs heatsink comparison helps in design decisions. A thermal pad (on PCB) is a built-in copper area, often plated and connected via thermal vias. It is internal and does not add extra height to the device. It’s subtle, efficient, and passive.

A heatsink, on the other hand, is a physical attachment—usually a metal block or finned structure—mounted on top of the component. It dissipates heat through air convection. While highly effective, heatsinks increase weight and require space. They may also need fasteners or thermal paste for better performance.

In low to medium-power circuits, thermal pads do the job silently. When current levels increase or the ambient conditions are harsh, heatsinks may be added. However, both solutions often work together. A pad draws the heat from the chip, and the heatsink then transfers it to the air.

Why Do We Need Thermal Pad on PCB?

We need thermal pads on PCBs to manage heat efficiently within confined board layouts. As chips grow more powerful and boards become smaller, heat density rises. Left unchecked, this can stress the materials, warp the PCB, or trigger thermal shutdowns in sensitive ICs.

Thermal pads provide a compact and cost-effective solution. Unlike external cooling systems, these pads are part of the board design. They reduce the thermal resistance between the component and the ground plane, making heat transfer faster and more efficient.

In LEDs, they stop lumen drop due to temperature spikes. In CPUs or RF amplifiers, they prevent drift in performance. Across industries, from smartphones to satellites, thermal pads are silent protectors against damage caused by thermal fatigue.

Design Consideration of Thermal Relief Pads on PCB

The design of thermal relief pads is not just about placing a copper square under a part. It demands precision. Several factors shape the design.

1. Pad Size: The area should match the component’s thermal tab. Oversized pads can cause solder wicking; undersized ones fail to transfer heat efficiently.

2. Vias Count and Diameter: Vias enhance heat transfer. Placing multiple small vias (0.3mm diameter with 6+holes) within the pad connects it to inner or bottom layers. These must be filled or tented to avoid solder leakage.

Design Consideration of Thermal Relief Pads on PCB

3. Copper Weight: Thicker copper layers enhance thermal conduction. A 2oz or 3oz copper layer works better than standard 1oz in high-heat zones.

4. Solder Mask Clearance: The pad must be free from mask to allow full thermal contact.

5. Connection to Planes: The pad should tie to ground or power plane, depending on the circuit. Use thermal relief spokes when needed to balance heat dissipation and solderability.

6. Component Package Type: Each package, whether QFN or TO-263, demands unique pad sizing and via patterns. Manufacturer datasheets offer recommended layouts—follow them closely.

When to Use Thermal Relief PCB?

Using a thermal relief PCB becomes necessary in several scenarios. One key use is in multilayer boards where copper planes absorb too much heat. Without thermal relief, soldering becomes difficult as heat spreads too quickly. This leads to cold joints or poor wetting.

Thermal reliefs help balance the heat flow. They allow soldering while still ensuring strong thermal performance. Another situation arises with through-hole components connected to large copper areas. Thermal relief spokes prevent the pad from acting like a heat sink during soldering.

Power applications like inverters, motor controllers, and regulators benefit from thermal relief PCBs. So do high-brightness LED arrays. In RF boards, where impedance matters, thermal pads also stabilize the electrical response by providing consistent grounding.

Use them when heat buildup could impair function or reduce board life. Proper relief design improves both manufacturing and operational performance.

PCB Aluminium Substrate, Aluminum PCB Board for LED

Thursday, April 17th, 2025

When it comes to reliable and advanced PCB solutions, Best Technology leads the way. With more than 18 years in the industry, we provide custom circuit board manufacturing for global clients. From prototype to volume production, we help you build better products with very good heat dissipation and military-grade quality. Our strength lies in metal-based PCBs, especially pcb aluminium substrates. These are widely used in LED, automotive, telecom, and power industries. With precision equipment and a strict quality system, we ensure high-performance boards that meet your needs.

What Is a PCB Aluminium Substrate?

A PCB aluminium substrate is a type of metal-based printed circuit board. (MCPCB) It uses aluminum as its base material instead of traditional FR4. This base supports layers of dielectric, and copper circuits. Aluminum PCBs offer strong heat dissipation and structural support compared with normal rigid PCB. The aluminum base acts as a heat sink. This makes the substrate ideal for high-power or thermally sensitive applications. In simple terms, it’s a PCB built on aluminum rather than fiberglass.

PCB Aluminium Substrate, Aluminium PCB Board for LED

Performance of Aluminium Substrate PCB in LED

Aluminum substrate PCBs are the backbone of today’s LED lighting systems. Their ability to manage heat is the most critical factor. When LEDs operate, they generate a lot of heat at the junction point. If that heat isn’t removed quickly, the LED’s brightness fades, and its lifespan shortens. Using an aluminum board for LED, we can get these benefits:

Efficient heat dissipation: The aluminum metal base acts as a built-in heat sink, pulling heat away from the LED source and spreading it across the board.
Improved reliability: By reducing thermal stress, the board helps extend the lifespan of each LED component. That means longer-lasting light and less need for replacement.
Stable light output: Overheating causes LEDs to dim. Aluminum PCBs maintain the thermal balance so that brightness stays consistent. Whether it’s a street lamp or a small indoor fixture, aluminum PCBs deliver stable operation.
Compact design: Since aluminum boards manage heat on their own, there’s no need for bulky external cooling systems.
Cost-effective: Although slightly more expensive than FR4, their longer lifespan and lower maintenance needs make them a better investment for lighting manufacturers.

6061 vs. 5052 vs. 1060 Aluminum Substrate

In the aluminum PCB manufacturing, the common aluminium substrates that manufacturers always use are 6061 aluminum substrate, 5052 aluminum substrate and 1060 substrate. All of them are aluminum allay, but the compositions and purity are different, so that the performance different too.

5052 aluminum sheet belongs to Al-Mg alloy, the main alloying element is magnesium, which has a content of 2.2% ~ 2.8%. In addition, it also contains a small amount of chromium (0.15%-0.35%) and other elements. The addition of which is intended to improve the strength and corrosion resistance of the alloy. 6061 aluminum sheet is Al-Mg-Si alloy, in addition to magnesium (0.8%-1.2%) and silicon (0.4%-0.8%) as the main alloying elements, copper (0.15%-0.4%) and zinc (less than 0.25%) are also added. 1060 aluminum material belongs to pure aluminum sheet, with an aluminum content of more than 99.6%, and almost no other alloying elements. Different alloy components form the basis of the different performances of these aluminum substrates. Below is a table comparison show the differences between each of them:

Property	6061 Aluminum	5052 Aluminum	1060 Aluminum
Composition	Magnesium & silicon alloy	Magnesium alloy	Pure aluminum (≥99.6%)
Thermal Conductivity	Moderate (150 W/m·K)	High (160 W/m·K)	Very high (≈237 W/m·K)
Strength of Extension	290MPa	215MPa	Low
Hardness	95HB	65HB	30HB
Elongation	10-18%	12-25%	5%
Formability	Low	High	High
Corrosion Resistance	Good	Excellent	Good
Common Uses	Structural parts, high-load PCBs	LED lights, flexible designs	High heat-dissipation PCBs
Cost	Higher	Medium	Lower

(6061 vs. 5052 vs. 1060 Aluminum Substrate)

So how to choose the suitable substrate for your aluminum PCB board? Follow this rule:

Choose 1060 if your project needs maximum thermal conductivity.
Choose 5052 if flexibility and corrosion resistance are more important.
Choose 6061 if you need strength and rigidity for heavy-duty PCBs.

What Is the Dielectric Layer of Aluminum PCB?

Aluminum substrate is generally composed of three layers: circuit layer (copper foil), dielectric layer and metal base. The dielectric layer is located between the circuit layer and the metal base layer, which acts as insulation and heat conduction. It is a polymer filled with high thermal conductivity and high insulation ceramic powder, make it is an ideal material with non-conductive but heat-conductive.

single sided PCB aluminium substrate structure

This dielectric layer has good heat conduction properties (thermal conductivity up to 3.0W/m-K), it is the key to thermal performance. It allows heat to pass from the copper to the aluminum while keeping them electrically isolated. The dielectric must have low thermal resistance and high breakdown voltage. Materials used often include ceramic-filled epoxy or polyimide. These support thermal conductivity while maintaining safety.

What Is the Difference Between FR4 and Aluminum PCB?

FR4 PCBs use fiberglass as a base. They are cheaper and more common. But they are poor at dissipating heat. They also deform more under thermal stress. Aluminum PCBs, on the other hand, handle heat much better. The aluminum pcb thermal conductivity is usually between 1.0 to 3.0 W/m·K. In contrast, FR4 is less than 0.3 W/m·K. That means aluminum PCBs can move heat away much faster. Here we listing the main differences between two of them:

Feature	FR4 PCB	Aluminum PCB
Base Material	Fiberglass-reinforced epoxy	Aluminum metal
Thermal Conductivity	≈0.3 W/m·K	1–3 W/m·K
Heat Dissipation	Poor	Excellent
Mechanical Strength	Moderate	High
EMI Shielding	Weak	Strong
Cost (under the same design complexity situation)	Lower	Slightly higher
Use Cases	Consumer electronics, PCs	Mainly used in led lights, automotive, power modules
Thickness Options	0.10mm, 0.12mm, 0.15mm, 0.20mm, 0.25mm, 0.30mm, 0.40mm, 0.50mm, 0.60mm, 0.80mm, 1.0 mm, 1.2 mm, 1.6mm, >=2.0 mm	0.30mm, 0.40mm, 0.50mm, 0.60mm, 0.80mm, 1.0 mm, 1.2 mm, 1.6mm, 2.0 mm, 2.4mm, 3.0mm (exclude copper)
Weight	Much lighter	Heavier but lighter than copper pcb
Environment Tolerance	Lower heat resistance	Withstands high temperatures

How Do You Make Aluminium PCB?

The manufacturing process of aluminum PCB is almost the same as normal FR4 PCB, except the lamination process of dielectric layer, aluminum and copper. This also is the biggest manufacturing difficult that faced by manufacturers, especially for multi-layer aluminum PCB. For the single & double sided aluminum PCB, the aluminum substrate we purchased from the manufacturers are laminated with dielectric, so we do not need to laminate again. In addition to this, the manufacturing process of aluminum PCB with insulated hole and without insulated hole are different.

Single-sided Aluminum PCB without insulated hole:

Cutting raw material (substrate laminated with dielectric layer) — Circuit layer generation (D-E-S) — Solder Mask – Silkscreen — Surface Treatment — Stripping — Drill Holes — Outline (V-cut – Routing – Die Punching) — QC — Package & Delivery

Single-sided Aluminum PCB without insulated hole

Single-sided Aluminum PCB with insulated hole:

Cutting raw material (substrate without laminated with dielectric layer) — Drill larger holes — Filled resin with holes — Lamination (dielectric layer + copper + aluminum base) — Circuit layer generation (D-E-S) — Solder Mask – Silkscreen — Surface Treatment — Stripping — Drill Holes — Outline (V-cut – Routing – Die Punching) — QC — Package & Delivery

Single-sided Aluminum PCB with insulated hole

Manufacturing Difficulties of Aluminum PCBs

Working with aluminum is not the same as working with FR4. It brings challenges, especially for a professional aluminum PCB manufacturer.

1. Mechanical Processing

Drilling holes on aluminum PCBs is possible, but the inner walls and board edges must be completely free of burrs. Even a slight burr can cause the board to fail the high-voltage test. Milling the outline is also quite difficult. The milling cutter used for FR4 PCB board has a relatively low hardness, while the milling cutter used for aluminum substrate has a high hardness. During the processing, the milling cutter for fiberglass board production has a high speed, while the milling cutter for aluminum substrate production has a speed at least 2/3 slower. As an alternative, punching with high-precision dies is often used—but die making requires exceptional skill, making this one of the main challenges in aluminum PCB manufacturing.

After punching, the edges must be clean and smooth, without any burrs or damage to the solder mask along the edges. Most factories use compound dies. Holes are punched from the circuit side, and the outline is punched from the aluminum side. This requires specific techniques, such as upward shearing and downward pulling during punching. Even after punching, the board’s warpage must be strictly controlled and should remain under 0.5%.

2. Protecting the Aluminum Surface During Processing

The aluminum base must remain completely free of scratches throughout the entire production process. Any direct contact with hands or chemicals can cause surface discoloration or oxidation, which are absolutely unacceptable. In many cases, re-polishing the aluminum surface is not allowed by customers. So, avoiding even the slightest damage to the aluminum layer is another major difficulty in the production process.

Some manufacturers use surface passivation treatments, while others apply protective films before and after hot air solder leveling (HASL). There are countless tricks and methods used to keep the surface clean—every factory has its own unique way of doing it.

3. High-Voltage Testing Requirements

For telecom power supply boards, 100% high-voltage testing is often mandatory. Some clients require DC testing, while others specify AC, typically at 1500V or 1600V for durations of 5 to 10 seconds. Every single board must pass this test.

Even the smallest contamination on the surface, burrs on holes or edges, jagged traces, or damage to the insulation layer can lead to arcing, leakage, or dielectric breakdown during testing. Boards that show signs of delamination or bubbling during the test are automatically rejected.

Despite these, trusted manufacturers like Best Technology handle it well. Our experience helps solve such problems early in the process.

How Much Does Aluminum PCB Cost?

Many factors influence the pcb aluminium substrate price. These include:

Aluminum grade (6061, 5052, or 1060)
Thickness of copper and base layer
Board size and layer count
Surface finish type
Quantity ordered
Special design features (e.g., thermal vias, contours)

In general, aluminum PCBs cost more than FR4 boards. But for heat-sensitive designs, the added cost pays off in reliability.

For instance, a basic one-layer aluminum PCB may start from $1.0–$5.0 per unit in bulk. Complex designs with multi-layers or special finishes can go higher. Best Technology offer competitive pricing without cutting corners. We also provide quick prototypes aluminium PCB substrate and full-scale production to meet your timeline and budget.

What is an SMD Resistor?

An SMD resistor is a surface-mounted component designed to limit current or divide voltage in electronic circuits, also known as Chip Fixed Resistor. It does the same job as a traditional resistor but without long leads. Instead, it sits directly on the PCB surface.

SMD stands for Surface-Mount Device. ‌The SMD resistor is usually in a flat package form and can be welded directly to the surface of the circuit board without the need to be connected by a connector. It is suitable for high-density assembly applications.

SMD Resistor Sizes, SMD Resistor Package Sizes Chart

Features of SMD Resistors

‌Dimensions‌: Usually expressed in 4 digits (imperial, unit: inches) or 2 digits + letters (metric, unit: millimeters). Common package sizes include 0201, 0402, 0603, 0805, 1206, etc.

‌Power rating‌: Based on 70°C ambient temperature, it needs to be derated in high temperature environments. For example, the power of a resistor in a 1206 package is 250mW at 100°C, and the actual available power needs to be reduced to 125mW‌. ‌

Resistance range‌: The resistance range of conventional resistors is 1Ω to 10MΩ. Low-resistance resistors are often used for current detection, with typical values of 0.005Ω to 0.1Ω‌. ‌

Accuracy‌: Common accuracy levels include ±5% (E24 series), ±1% (E96 series), ±0.5%, ±0.1% (high precision). ‌

Temperature coefficient: The temperature coefficient of conventional thick film resistors is ±200ppm/°C to ±400ppm/°C, and the temperature coefficient of precision thin film resistors is ±25ppm/°C to ±50ppm/°C.

SMD Resistor Package Sizes Chart

The shapes and sizes of surface-mount resistors have been standardized, and most manufacturers follow JEDEC standards. SMD resistors are typically identified by numerical codes, such as 0603, which indicate the package’s length and width. For instance, the 0603 imperial code refers to a resistor that is 0.060 inches long and 0.030 inches wide.

SMD package codes can be given in either imperial or metric units. In general, imperial codes are more commonly used to describe package sizes. However, it can be confusing because even when imperial codes are used, the actual dimensions are often referred to in millimeters during the PCB design process. Below is a table of SMD resistor package sizes chart, listing the dimensions and specifications of commonly used SMD resistor packages.

Imperial Code	Metric Code	Length (mm)	Width (mm)
0201	0603	0.6	0.3
0402	1005	1.0	0.5
0603	1608	1.6	0.8
0805	2012	2.0	1.25
1206	3216	3.2	1.6
1210	3225	3.2	2.5
1812	4532	4.5	3.2
2010	5052	5.0	2.5
2512	6432	6.4	3.2

(SMD Resistor Package Sizes Chart)

The smaller the code, the smaller the component. For example, 0201 resistors are tiny and used where space is limited, like in smartwatches or hearing aids.

What Do the Numbers on SMD Resistors Mean?

The numbers printed on an SMD resistor represent its resistance value. These markings follow a system called EIA-96 or 3-digit/4-digit code.

For the 3-digit system:

The first two digits are significant figures.

The third digit is the multiplier (number of zeros to add).

Example:

Code “472” means 47 * 100 = 4,700 ohms.

What Do the Numbers on SMD Resistors Mean?

For the 4-digit system (used in precise resistors):

The first three digits are the base value.

The fourth is the multiplier.

Example:

Code “4702” means 470 * 100 = 47,000 ohms or 47kΩ.

How to Read SMD Resistor Code?

Reading the code on an SMD resistor might seem tricky at first. But once you understand the logic behind the numbers and letters, it becomes simple. SMD resistors don’t have color bands like traditional through-hole types. Instead, they use numbers—or sometimes numbers and letters—printed directly on the component. There are 4 ways to read the smd resistor values:

1. 3-Digit Code Format (Most Common)

This is the most widely used format for general-purpose SMD resistors. The first two digits represent significant figures, and the third digit is the multiplier (in powers of ten).

Example:

“472”

First two digits: 47
Third digit (multiplier): 2 → means 10² = 100
So the resistance = 47 × 100 = 4700 ohms or 4.7kΩ

Another example:

“101” → 10 × 10¹ = 100 ohms

If you see a code like “220”, it’s 22 × 10⁰ = 22 ohms

2. 4-Digit Code Format (For Higher Accuracy Resistors)

This is used for resistors with tighter tolerance. The first three digits are significant figures, and the fourth digit is the multiplier.

Example:

“1001”

First three digits: 100
Fourth digit: 1 → 10¹ = 10
Resistance = 100 × 10 = 1,000 ohms or 1kΩ

Another example:

“4702” → 470 × 100 = 47,000 ohms or 47kΩ

3. Codes with “R” (Used for Decimal Values)

When the resistance is below 10 ohms, the code often includes the letter “R” to indicate a decimal point.

Examples:

“4R7” → 4.7 ohms

“0R22” → 0.22 ohms

“R100” → 0.1 ohm

This format helps avoid confusion, as a simple “047” might be misunderstood. “R” clearly marks the decimal location.

4. Zero Ohm Resistors

If you ever see a resistor labeled “000” or “0”, this is a zero-ohm jumper. It acts like a wire and is often used for PCB routing flexibility. There’s no resistance value to read—it’s simply a bridge.

0201 SMD Resistor Dimensions

The 0201 SMD resistor is one of the smallest types used today. It measures:

Length: 0.6 mm
Width: 0.3 mm
Height: around 0.23 mm

Because of its tiny size, handling 0201 resistors requires advanced assembly machines and tight process control. These resistors are found in:

Smart wearables
High-end smartphones
Advanced medical devices

Despite their size, they offer solid performance and accuracy when mounted correctly.

What is the Difference Between SMD and SMT Resistor?

Many confuse SMD with SMT. They are related but not the same:

SMD (Surface Mount Device) refers to the actual component. A resistor, capacitor, diode—any small chip-shaped part.
SMT (Surface Mount Technology) is the method used to attach these components to a PCB.

So, a SMD resistor is a type of part, while SMT is the process used to mount it. Think of it like this: SMD is the “what,” and SMT is the “how.”

In a factory, SMT lines are the equipment and process flow. SMD is what they’re working with. Both are key in modern electronics manufacturing.

SMD Resistor Applications and Benefits

SMD resistors are everywhere. Here are some common uses:

Consumer electronics (phones, tablets, TVs)
Automotive systems (ECUs, sensors)
Industrial controls (inverters, PLCs)
Medical devices (monitors, implants)
Telecommunication Infrastructure (routers, switches, and base stations)
Wearables and IoT Devices (Fitness trackers, smartwatches, and IoT sensors)
Aerospace and Defense

The benefits are plenty:

Compact size
High reliability
Excellent thermal stability
Automated assembly
Good frequency response

They help companies build faster, lighter, and smarter products. That’s why SMD resistors are chosen for both low-cost gadgets and mission-critical equipment.
