New energy vehicle electric drive, OBC (on-board charger), DC-DC converter and other power modules commonly use aluminum/copper based metal core printed circuit boards (MCPCBs), which conduct heat directly through the metal substrate, reducing the IGBT junction temperature by more than 20 ?.
Industry data shows that by 2025, the installation volume of MCPCB vehicles in the automotive grade will increase by over 65% year-on-year, penetrating from high-end models to mainstream A-class vehicle platforms.
This application highlights the extension of PCB from an “interconnect carrier” to a “thermal management component”, forcing the upgrading of substrate materials, insulation layer processes, and reliability testing standards.
