Product type
Metal Core PCBs, or MCPCBs, are a type of printed circuit board that utilizes a metal substrate, typically aluminum or copper, to provide enhanced thermal conductivity. This design allows for efficient heat dissipation, making them ideal for high-power applications. MCPCBs are commonly used in LED lighting, power supplies, and other electronic devices where heat management is critical.
| Material | Aluminum, copper, or other metal substrates |
| Layer count | 1 to 10 layers |
| Thickness | 0.8 mm to 3.2 mm |
| Thermal conductivity | 1.0 to 5.0 W/mK |
| Copper weight | 1 oz to 4 oz |
| Surface finish | HASL, ENIG, OSP, or immersion silver |
When selecting Metal Core PCBs, consider the thermal management requirements of your application, including the necessary thermal conductivity and copper weight. Specify the number of layers, thickness, and surface finish that best suits your design. Additionally, inquire about any certifications required for your industry, such as UL or RoHS compliance, and provide estimated quantities to receive accurate quotes.
