A simple layer single sided MCPCBconsists of a metal base (usually aluminum, or copper alloy), Dielectric (non-conducting) Layer, Copper Circuit Layer, IC components and solder mask.
The prepreg dielectric provides excellent heat transfer from the foil and components to the base plate, while maintaining excellent electrical isolation. The base aluminum/copper plate gives the single-sided substrate mechanical integrity, and distributes and transfers the heat to a heat sink, mounting surface or directly to the ambient air.
The Single-Layer MCPCB can be used with surface mount and chip & wire components, and provides much lower thermal resistance than FR4 PWB. The metal core provides lower cost than ceramic substrates, and allows much larger areas than ceramic substrates.

Single Layer MCPCB FAQs
1. What is a single layer MCPCB?
A single layer MCPCB consists of a metal base (typically aluminum or copper), a non-conductive dielectric layer, and a copper circuit layer. Unlike standard PCBs, the metal core acts as a primary heat sink, moving thermal energy away from high-power components to the environment or an external cooling system.
2. How does a single layer MCPCB differ from a standard FR4 PCB?
The primary difference is the substrate material. While FR4 uses fiberglass and epoxy, an MCPCB uses a metal base. This allows MCPCBs to have significantly higher thermal conductivity. While a standard FR4 board typically has a conductivity of around 0.25 W/mK, a single layer MCPCB can range from 1.0 W/mK to 9.0 W/mK depending on the dielectric material used.
3. What are the typical applications for single layer MCPCBs?
Single layer MCPCBs are most commonly used in the LED lighting industry (street lights, automotive headlamps, and backlight units) because LEDs generate significant heat that can degrade performance if not dissipated. They are also widely used in power conversion, solid-state relays, and the automotive sector for motor control modules.
4. Can you have plated through-holes (PTH) on a single layer MCPCB?
Generally, no. In a standard single layer MCPCB, the metal base is conductive, so through-holes would cause a short circuit between the signal layer and the base. Components are typically Surface Mount Devices (SMD). If through-hole components are required, specialized “COB” (Chip on Board) or complex insulated hole processes are needed, which significantly increases cost.
5. What are the layers of a single layer MCPCB?
A standard stack-up includes four main layers:
Solder Mask: Protects the copper circuit.
Circuit Layer: The copper foil used for traces.
Dielectric Layer: The most critical part; it provides electrical insulation while facilitating heat transfer.
Metal Substrate: Usually 1.0mm to 3.2mm of Aluminum (5052 or 6061) or Copper.
6. Is aluminum or copper better for the metal core?
Aluminum is the most popular choice because it is cost-effective and provides excellent thermal dissipation for most applications. Copper offers even higher thermal conductivity but is much heavier and more expensive. Copper is usually reserved for extremely high-power density applications where aluminum’s performance is insufficient.

Which is difference between metal core PCBand FR4? This article compares the structural characteristics, thermal performance, and applicable scenarios of metal core and FR4 PCBs, providing accurate selection guidance.
A Metal Core PCB(MCPCB) is a printed circuit board with a metal base layer, typically aluminum or copper, designed for efficient heat dissipation in high-power applications. Its three-layer structure consists of copper circuitry, dielectric insulation, and metal core, enabling superior thermal management.
This makes it ideal for LED lighting, automotive electronics, and industrial power systems. The metal core acts as a heat sink, transferring heat away from components to prevent overheating while maintaining electrical insulation through the dielectric layer. This design ensures reliable performance in high-temperature environments.
What Is a FR4 PCB?
FR4 PCB is a printed circuit board made from FR-4 material, a flame-retardant glass fiber reinforced epoxy resin composite widely used in electronics due to its excellent mechanical strength, electrical insulation, and thermal stability.
It serves as a reliable substrate for mounting components while ensuring dimensional stability under varying environmental conditions鈥. The material’s UL94 V-0 flammability rating and cost-effectiveness make it the standard choice for most consumer electronics, industrial equipment, and communication devices.
What Is the Difference? Metal Core PCB vs FR4
Material Composition & Structure
FR4 PCB: Manufactured from woven glass fiber impregnated with epoxy resin, this composite material offers insulation and mechanical strength. Its mature fabrication process supports multi-layer stacking for complex circuit designs, with copper traces plated on surfaces, ideal for standardized electronic module production.
Metal Core PCB: Built with aluminum or copper substrates in a “sandwich” architecture (circuit layer-insulation layer-metal base), the metal layer provides thermal support. Aluminum substrates are lightweight and cost-effective, while copper substrates deliver superior thermal conductivity (>380W/m路K). Insulation layers often use thermal silicone or ceramic-filled materials to balance electrical isolation and heat conduction.
Thermal Performance
FR4 PCB: Thermal conductivity ~0.3W/m路K, weak heat dissipation suitable for low-to-mid power applications. In LED modules or low-power supplies, external heatsinks are required to prevent thermal buildup that raises chip junction temperatures and shortens lifespan.
Metal Core PCB: Thermal conductivity ranges from 1-380W/m路K (aluminum: 1-3W/m路K, copper: >380W/m路K), achieving 6-9 times higher efficiency than FR4. For example, in automotive LED headlights, copper substrates rapidly dissipate heat from IGBTs, preventing light decay or burnout.
CTE Matching
FR4 PCB: Coefficient of Thermal Expansion (CTE) 12-24ppm/掳C, significantly differing from copper鈥檚 17ppm/掳C, leading to delamination risks under thermal stress. Repeated thermal cycling may cause micro-cracks at FR4-copper interfaces, reducing electrical reliability.
Metal Core PCB: CTE closely matches copper (e.g., aluminum: 24ppm/掳C), minimizing thermal cycling failure risks. The low CTE differential ensures stable electrical connections in high-reliability applications like aerospace or industrial control systems.
Mechanical Strength & Environmental Adaptability
FR4 PCB: Flexural strength ~480MPa, suitable for consumer electronics but prone to deformation under high temperature/pressure. While stable in everyday devices, it risks board fracture in vibration-heavy industrial environments.
Metal Core PCB: Metal substrates enhance rigidity, vibration/impact resistance, and suitability for extreme conditions like automotive electronics or industrial equipment. For instance, in new energy vehicle motor controllers, aluminum substrates withstand high-frequency vibrations and thermal shocks, ensuring circuit stability.
Electrical Performance
CDielectric constant 4.0-4.8, loss tangent 0.01-0.02, optimal for mid-to-low frequency signal transmission. Enables low-loss signal routing in communication devices, supporting high-frequency/high-speed designs.
Metal Core PCB: High-frequency performance depends on insulation layer design. While typically prioritized for thermal management, electrical performance slightly lags FR4. Optimized insulation materials (e.g., low-dielectric polymers) can balance high-frequency signal integrity with thermal efficiency.
Cost & Processing
FR4 PCB: Low cost, easy processing, and compatibility with complex multi-layer designs. Mass-produced by standard PCB factories at 1/3 to 1/5 the cost of metal core PCBs, ideal for large-scale consumer electronics.
Metal Core PCB: Higher costs due to specialized processing (e.g., metal substrate etching, precision drilling) and single/simple multi-layer structures. Despite elevated per-unit costs, long-term thermal management benefits reduce system maintenance expenses.
Application Scenarios
FR4 PCB: Dominates general-purpose fields like consumer electronics, communication devices, and home appliances (e.g., smartphone motherboards, router PCBs), leveraging low cost and mature processes for rapid iteration.
Metal Core PCB: Targets high-power, thermally demanding scenarios such as LED lighting, power modules, automotive electronics, and industrial equipment (e.g., streetlight drivers, EV battery management systems), optimizing thermal management to enhance device reliability.
Why Are Metal Core PCBs Better at Dissipating Heat than FR4 PCBs?
Reasons why MCPCB better at dissipating heat than FR4 PCB:
Direct Thermal Path via Metal Substrate: Aluminum/copper substrates in Metal Core PCBs create a vertical thermal channel from the chip through the insulating layer to the metal base. This bypasses FR4鈥檚 multi-layer dielectric thermal resistance stack-up, reducing thermal resistance by 60-90%. For example, in IGBT modules, copper-based PCBs can lower junction temperatures by 20-30掳C, directly extending device lifespan.
Optimized Insulation Layer Materials: Metal Core PCBs use thermally conductive silicones, ceramic fillers (e.g., AlN), or nano-composites as insulating layers. These materials balance electrical isolation with high thermal conductivity (5-20W/m路K for AlN-filled layers vs. FR4鈥檚 0.3W/m路K), creating a “thermal short-circuit” effect for rapid heat transfer.
Active Thermal Structure Design: Metal substrates can be machined with fins, thermal via arrays, or embedded heat pipes to actively expand surface area. In LED streetlights, aluminum substrates with radial fins increase heat dissipation area by 300%, enabling passive air cooling without additional fans.
Thermal-Mechanical Stability: Metal鈥檚 high rigidity minimizes thermal deformation impacts on circuits. In automotive power systems, aluminum substrates exhibit <0.1% warpage across -40掳C to 125掳C cycles, compared to FR4鈥檚 >0.5% deformation that risks solder joint fatigue.
System-Level Thermal Integration: Metal Core PCBs integrate directly with enclosures/heatsinks to form a unified thermal management chain. In 5G base station power modules, copper substrates bond with aluminum chassis for large-area passive cooling, reducing reliance on active cooling components and lowering system complexity/cost.
Why is Metal Core PCB More Suitable for High-Power Application Than FR4 PCB?
Superior Thermal Conductivity Materials
Metal core PCBs utilize copper (385 W/mK), aluminum (200 W/mK), or steel alloys with thermal conductivity 50-1000 times higher than FR4 (0.4 W/mK). This allows rapid heat dissipation from components, preventing thermal buildup-induced performance degradation or failure. For example, in 1000A automotive IGBT modules, copper substrates limit temperature rise to 鈮30鈩, while FR4 may trigger thermal protection due to localized overheating.
3D Heat Conduction Architecture
Thermal via arrays (0.1mm micro-vias at 100 holes/cm虏 density), embedded copper blocks (0.5-2mm thick), and metal backplate heat sinks form a tiered heat conduction path: component 鈫 thermal vias 鈫 substrate 鈫 external heatsink. This vertical heat transfer achieves 3-5 times higher efficiency than FR4鈥檚 planar heat spreading, ideal for high-power-density scenarios like LED streetlights and 5G base station PA modules.
Enhanced Heat Diffusion & Thermal Uniformity
High thermal diffusivity of metals (e.g., aluminum at 97 mm虏/s) enables heat to spread evenly across the substrate within 0.1 seconds, avoiding localized hotspots that plague FR4 (thermal diffusivity: 0.3 mm虏/s). During 150鈩 thermal shock tests, metal core PCBs exhibit stable temperature profiles, whereas FR4 shows stepwise heating that risks component thermal stress cracking.
Low-Resistance Heat Dissipation Path
Direct contact between component pads and the metal substrate via high-conductivity solder (e.g., SnAgCu) achieves thermal resistance as low as 0.1鈩/W鈥攕ignificantly lower than FR4鈥檚 insulation layer resistance (>10鈩/W). This direct path minimizes interlayer thermal resistance accumulation, ensuring stable high-power operation.
Metal substrates withstand temperatures >300鈩 (e.g., copper), while FR4 softens above 130鈩, risking delamination or solder joint failure. Metal core PCBs pass 1000-hour 85鈩/85%RH CAF (Conductive Anodic Filament) tests for corrosion resistance, outperforming FR4鈥檚 500-hour limit and reducing long-term failure rates.
Extreme Environment Adaptability
In aerospace and deep-sea applications, metal core PCBs endure -55鈩 to 125鈩 temperature swings, high pressure, and salt spray without degradation. FR4, prone to moisture absorption and insulation breakdown, fails in such conditions鈥攅.g., satellite power modules rely on steel alloy substrates for vacuum stability.
How Does Cost Difference between FR4 and Metal Core PCB?
The unit price of a standard double-sided FR4 PCB (1.6mm thickness) is approximately $2-$5 per piece. Leveraging a mature supply chain and the low-cost advantages of glass fiber substrates, it is suitable for large-scale mass production, with the unit price for an order of 10,000 pieces being reduced to $0.5 per piece. Metal core PCBs (MCPCBs) of the same size cost $15-$50 per piece, 7-10 times the cost of FR4.
This is mainly due to the high price of aluminum/copper core substrates (approximately $10-$30/銕, 3-5 times the cost of FR4 substrates), the need for specialized surface treatment processes such as drilling and anodizing (which increase manufacturing costs by 30%-50%), and the difficulty in allocating processing losses in small-batch production, limiting the room for cost reduction.
How to Choose between Metal Core PCB and FR4 PCB?
Clarify Power Requirements & Thermal Constraints
High-power scenarios (鈮50W/cm虏 heat density): Choose metal core PCB (aluminum/copper-based) for 6-9x higher thermal conductivity (1-380W/m路K vs. FR4鈥檚 0.3W/m路K), preventing overheating in LED lighting, power modules, or automotive IGBTs.
Low-power scenarios (锛20W/cm虏): Optimize for FR4 due to lower cost and mature fabrication, ideal for consumer electronics and home appliances.
Evaluate Environmental Resilience
Extreme conditions (high temp/vibration/humidity): Metal core PCB鈥檚 rigid metal base (2-3x stronger than FR4) withstands shocks in automotive power systems or industrial drives.
Standard environments (indoor/low-vibration): FR4 suffices for basic mechanical strength in routers or phone motherboards.
Balance Cost & Long-Term Benefits
Budget-sensitive/mass production: FR4 wins with low material costs, complex multi-layer support, and quick scaling.
High reliability/longevity focus: Metal core PCB reduces secondary cooling costs (e.g., heat sinks/fans) and extends device life, justifying its higher unit cost in 5G power supplies.
Match Electrical & Signal Requirements
High-frequency applications (鈮1GHz): FR4鈥檚 superior dielectric constant (4.0-4.8) and loss tangent (0.01-0.02) suit fine-line RF designs.
Thermal-priority scenarios (e.g., LED drivers): Metal core PCB balances heat dissipation with optimized insulators like thermal silicone.
Consider Thermal Expansion Compatibility
Frequent thermal cycling (outdoor/industrial control): Metal core鈥檚 CTE (e.g., aluminum: 24ppm/掳C) aligns with copper traces (17ppm/掳C), minimizing interface stress and delamination risk.
Stable thermal environments (indoor): FR4 works with stress-relief designs (e.g., thermal buffer layers) at lower cost.
Factor in Design Complexity & Manufacturability
Complex multi-layer/high-density interconnects: FR4鈥檚 mature processes support intricate stacking and fine-pitch routing.
Simple/single-layer thermal-centric designs: Metal core PCB鈥檚 streamlined structure reduces manufacturing complexity, ideal for cost-sensitive thermal applications.
Assess Sustainability & Recycling Potential

Enhanced Lifespan: By keeping components cooler, it reduces wear and tear, extending the operational life of solar charging systems or inverters.
How to Enhance 1 Layer MCPCB Heat Dissipation to Extend Outdoor Solar Cells Lifespan?
Choose High-Conductivity Substrates: Use copper (385 W/m路K) for the metal core if weight allows. For lighter builds, select 1.5mm+ thick aluminum (237 W/m路K) with a matte finish to boost radiative cooling under sunlight.
Use Advanced Dielectric Materials: Replace standard epoxy with ceramic-filled polyimide (1.5鈥3 W/m路K) in the insulating layer. This cuts thermal resistance by 40鈥60%, accelerating heat transfer to the substrate.
Maximize Thermal Via Efficiency: Drill 0.3mm copper-plated vias beneath heat-generating components (e.g., diodes, MPPT chips) at 1mm spacing. Arrange vias in a grid pattern to create vertical heat pathways.
Integrate Passive Cooling Elements: Attach finned aluminum heat sinks (10鈥20mm tall) to the MCPCB鈥檚 backside. In compact spaces, use graphite sheets (1,500 W/m路K) or vapor chambers to spread heat evenly across the substrate.
Apply Emissivity-Enhancing Coatings: Coat the metal core鈥檚 exterior with black ceramic paint (emissivity >0.85). This increases infrared radiation, helping the board shed heat faster under direct solar exposure.
Optimize Component Layout: Place high-power components (e.g., transistors) away from solar cell active zones. Use thermal gap pads (2鈥4W/m路K) to ensure direct contact between parts and the MCPCB surface.
Validate with Thermal Modeling: Use ANSYS Icepak or similar tools to simulate heat flow. Adjust via patterns, material thickness, or component positions based on hotspot analysis (e.g., reduce via spacing in 50掳C+ zones).
How to Improve 1-Layer MCPCB Reliability for Outdoor Solar Cells?
Select Durable Materials
Use aluminum (lightweight, corrosion-resistant) or copper (high conductivity) for the metal core. Pair with polyimide or modified epoxy dielectric layers to resist moisture and delamination while ensuring efficient heat transfer.
Boost Thermal Performance
Increase thermal via density under high-heat components (e.g., solar charge controllers) to direct heat to the metal base. Thicken the substrate (e.g., 2mm aluminum) or add external heat sinks for passive cooling, reducing active system reliance.
Apply Protective Coatings
Coat circuits with UV-resistant, waterproof conformal coatings (e.g., silicone for coastal areas) to shield solder joints and traces from humidity, dust, and salt spray.
Use Robust Components
Choose outdoor-rated parts (e.g., capacitors rated for -40掳C to 125掳C) and high-reliability solder (e.g., SAC305).
Strengthen Design and Test
Match dielectric layer CTE to metal and copper traces to prevent cracking. Secure edges with epoxy or fasteners for vibration resistance. Validate with 1,000+ hours of 85掳C/85%RH damp heat, thermal shock (-40掳C to 125掳C), and salt-spray tests.
How to Enhance 1-layer MCPCB Durability for Harsh Outdoor Conditions?
Use Corrosion-Resistant Substrates
Select anodized aluminum (5052 alloy) for coastal or industrial areas. Anodizing creates a 5鈥25碌m oxide layer that resists salt and moisture. In extreme corrosion environments, choose 316 stainless steel despite its higher weight.
Apply Multi-Layer Protective Coatings
Coat circuits with a 50鈥100碌m silicone-based layer (e.g., Dow Corning 1-2577) to block moisture and dust. Add a 20鈥30碌m acrylic topcoat for scratch resistance, focusing on solder joints and exposed traces.
Reinforce Mechanical Stability
Thicken the dielectric layer to 100碌m polyimide to reduce flexing under thermal stress. Secure board edges with epoxy adhesive or aluminum brackets to prevent warping from temperature swings (-40掳C to 125掳C) or vibration.
Choose Outdoor-Rated Components
Use IP67-rated capacitors, resistors, and connectors with a -40掳C to 125掳C operating range. Select gold-plated contacts for connectors to resist tarnishing in humid environments.
Match Thermal Expansion Properties
Select dielectric layers with a coefficient of thermal expansion (CTE) close to aluminum (23鈥24 ppm/掳C). Ceramic-filled polyimide (CTE 12鈥18 ppm/掳C) reduces stress on copper traces during temperature fluctuations.
Validate with Accelerated Aging
Perform 2,000-hour thermal cycling (-40掳C to 125掳C, 1-hour dwells) and 96-hour salt-spray tests (ASTM B117). Include UV exposure (ISO 4892-3) to confirm coating integrity under prolonged sunlight.

A sinkpad copper based PCB, also known as SinkPAD board or thermoelectric copper separation copper based PCB, is a specialized type of metal core printed circuit board. It mainly consists of two major parts: the top trace layer and the copper core/substrate. The top trace layer contains the electrical traces for the circuit, while the copper core serves as a heatsink.
A 1 – Layer SinkPAD board, a common type, consists of a copper circuit layer, a dielectric (non – conducting) layer, and a metal core/pedestal which is usually copper. It belongs to single – sided SinkPAD PCB and DTP (Direct Thermal Path) board, and is the most popular and cost – effective stack – up option with the fastest lead time.
Why Use Sinkpad Copper Based PCB?
Sinkpad copper based PCBs are used for several important reasons. After lamination, the electronics connection is on the trace layer, and the direct thermal conducting PAD comes from the copper core. The trace PAD on the trace layer is in the sink area of the copper core, which gives it the name 鈥淪inkPAD board鈥. This design allows for efficient thermoelectric separation.
These PCBs can reach a thermal conductivity of 400W/m.K. This high thermal conductivity is crucial in applications where heat dissipation is a major concern, such as in high – power LED lighting, power electronics, and other electronic devices that generate a significant amount of heat. By effectively dissipating heat, sinkpad copper based PCBs can improve the performance and reliability of electronic components and extend their lifespan.
Factors Affect the Price of Sinkpad MCPCB
Material type (aluminum vs. copper)
The choice of material has a significant impact on the price of sinkpad MCPCB. Copper is generally more expensive than aluminum. Copper has excellent thermal conductivity, which is one of the key advantages for sinkpad PCBs as it helps in better heat dissipation. However, the higher cost of copper raw materials and the more complex processing requirements contribute to the increased price.
Aluminum, on the other hand, is a more cost – effective option. It has relatively good thermal conductivity and is lighter in weight. But its thermal performance is not as good as copper. When the application requires high – end thermal performance, copper is often the preferred choice, but it comes at a higher price.
Board size and thickness
The size and thickness of the sinkpad copper based PCB also play a role in determining the price. Larger boards require more raw materials, such as copper and dielectric materials. Additionally, the manufacturing process for larger boards may be more complex, as it requires more precise alignment and processing steps.
Thicker boards also add to the cost. Thicker copper cores or additional layers of materials increase the material cost. Moreover, thicker boards may require more advanced manufacturing techniques to ensure proper electrical and thermal performance, which can drive up the production cost.
Layer structure
The layer structure of the sinkpad PCB is another important factor. A more complex layer structure, such as multi – layer sinkpad PCBs, is more expensive than single – layer ones. Multi – layer PCBs require more manufacturing steps, including additional lamination processes, drilling for vias to connect different layers, and more precise alignment of the layers.
Each additional layer adds to the complexity and cost of the manufacturing process. For example, a 1 – Layer SinkPAD board is the simplest and most cost – effective option, while a PCB with multiple trace layers and copper core layers will be significantly more expensive.
Order quantity
Order quantity has a direct impact on the price of sinkpad copper based PCBs. When the order quantity is large, the per – unit cost usually decreases. This is because manufacturers can take advantage of economies of scale. They can purchase raw materials in bulk at a lower cost, optimize their production processes, and reduce setup costs per unit.
For small – quantity orders, the fixed costs associated with setting up the production line, such as tooling costs and programming costs, are spread over a smaller number of units. As a result, the per – unit price is higher. So, customers who need a large number of sinkpad PCBs can often negotiate a better price per unit.
Custom thermal pad design
Custom thermal pad designs can also increase the price of sinkpad copper based PCBs. Standard thermal pad designs are more cost – effective because they can be produced using existing manufacturing processes and tools. However, if a customer requires a custom thermal pad design, it may involve additional engineering work, such as designing new masks, adjusting the manufacturing process, and conducting additional testing.
Custom designs may also require special materials or manufacturing techniques to meet the specific thermal requirements. All these additional steps and requirements add to the overall cost of the PCB.
Sinkpad Copper Based PCB Applications
Sinkpad copper based PCBs have several common uses in the electronics industry:
Thermoelectric separation applications:
Since the trace layer of SinkPAD boards is usually on the top side, they belong to single – sided SinkPAD PCBs and Direct Thermal Path (DTP) boards. This makes them suitable for applications where thermoelectric separation is required. For example, the SinkPad board provides excellent heat transfer from the LED to the base metal (copper) plate while maintaining excellent electrical isolation.
High – power LED applications:
1 – Layer copper base SinkPad PCB: It can be used with surface mount and chip & wire components. The thermal PAD of the LED touches the convexity of the copper core/pedestal directly, achieving a thermal conductivity of 400W/m.K. The pad of the LED touches the copper base directly, allowing the heat generated by the LED to be dissipated quickly into the air or a heatsink, achieving the best heat dissipation and conduction.
2 – Layers copper base SinkPad PCB: It can also be used with surface mount and chip & wire components. Similar to the 1 – layer version, the thermal PAD of the LED touches the convexity of the copper core/pedestal directly, with a thermal conductivity of 400W/m.K.
In general, sinkpad copper based PCBs are used to provide superior thermal performance for medium – to high – power LEDs and other chips/components.
How Does A SinkPAD board Differ From A Traditional PCB?
A SinkPAD board is a special type of metal core PCB. In a SinkPAD board, the thermal conductive PAD is the convexity area of the copper core/pedestal, allowing the thermal PAD of the LED to touch the convexity area of the metal core directly. This enables the heat of the LED to be dissipated into the air much faster and more efficiently than a conventional PCB.
The SinkPad provides excellent heat transfer from the LED to the metal base plate/pedestal while maintaining excellent electrical isolation. The base copper base gives the board substrate mechanical integrity, distributes and transfers the heat to a heat sink, mounting surface, or directly to the ambient air.
In contrast, traditional PCBs do not have this direct thermal path feature. The heating of the LED in a SinkPAD board conducts directly into the copper core, which is different from the traditional thermal path. Due to this, a SinkPAD board can offer superior thermal performance for medium – to high – power LEDs or other chips/components.
How to Design a SinkPAD Board?
When designing a SinkPAD board, the following points need attention:
1. Panel layout design
If the board outline is not square or rectangle, the outline has to be made via CNC routing or Die – punching. While designing the panel layout, at least 2mm space between the edge of the SinkPAD board (SinkPAD PCB) should be kept in order for routing or Die – punching.
2. Routing and punching
Several layers of SinkPAD PCB will be routed together to save time. But for punching, there is only one layer of SinkPAD board (SinkPAD PCB) each time. Die – punching will be used only when there are big volume orders as the cost of die – punching tooling is higher compared with other ways.
Moreover, in the lamination process (laminate & align board before hot process lamination), after specific steps, the electronics connection will be on the trace layer and the direct thermal conducting PAD comes from the copper core. The trace PAD on the trace layer seems in the sink area of the copper core, which is how the SinkPAD board gets its name. And because the electronic – related function is on the trace layer and thermal conduction is on the copper core, they are separated from each other, so it is also named a Thermoelectric separation circuit board.
