POWER MODULE METAL WIRING BOARD, POWER MODULE, POWER MODULE BOARD, AND METHOD FOR MANUFACTURING POWER MODULE METAL WIRING BOARD

摘要

PROBLEM TO BE SOLVED: To provide a power module board and a power module metal wiring board, including a metal board, an insulating layer and a conductive metal wiring layer mutually laminated in close contact, and having heat dissipation and heat resistance of a power module with improved reliability, and to provide a method for manufacturing the power module and the power module metal wiring board.SOLUTION: In the power module metal wiring board at least having the metal board, the insulating layer and the conductive metal wiring layer laminated in sequence, there are provided two insulating layers including a non-thermoplastic insulative resin layer and a thermoplastic insulative resin layer, and a filler, to thereby enable close contact to the metal board and the conductive metal wiring layer, with heat dissipation, heat resistance and improved reliability.
