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.
