What is Metal Core PCB?
Metal Core PCB (MCPCB) is a high-efficiency thermal management circuit board with a metal substrate as the base carrier, mainly divided into aluminum core PCB and copper core PCB. Different from standard FR4 PCBs, it adds a metal heat-conducting base and a low-thermal-resistance insulating layer, solving the heat dissipation bottleneck of high-power electronic components.
- Classified Metal Substrate Selection
We adopt cost-effective aluminum for regular heat dissipation scenarios and high-performance copper for ultra-high heat flux precision applications.
- Low-Thermal-Resistance Insulation Design
Premium dielectric materials greatly reduce thermal resistance, enabling fast and uniform overall heat transfer.
- High-Temperature & Structural Stability
The integrated metal core effectively resists warpage and delamination, ensuring stable long-term high-temperature operation.
