What Is a Metal Core PCB (MCPCB)? A Metal Core Printed Circuit Board (MCPCB) uses a metal substrate—typically aluminum, copper, or iron alloy—as the core layer instead of standard FR4 dielectric material. Thanks to the high thermal conductivity of metal substrates, MCPCBs can efficiently dissipate heat generated by high-power electronic components, making them essential for:...
1. Why Thermal Conductivity of Metals Matters in PCB Applications Metals are widely used in electronic devices and printed circuit boards (PCBs) due to their excellent electrical and thermal properties. However, not all metals conduct heat equally. High thermal conductivity metals rapidly transfer heat and are ideal for heat dissipation Low thermal conductivity metals restrict...
1. Why Heat Dissipation Has Become a Critical PCB Design Challenge With the rapid development of integrated circuits (ICs) and microelectronic packaging technologies, electronic systems are becoming: Smaller in physical size Higher in power density More integrated and compact As a result, heat flux density around electronic devices continues to rise sharply. Excessive heat accumulation...
