HEAT DISSIPATION STRUCTURE POWER MODULE METHOD FOR MANUFACTURING HEAT DISSIPATION STRUCTURE AND METHOD FOR MANUFACTURING POWER MODULE

摘要

bond strength is high in the heat cycle, and the cooling efficiency high heat dissipation structure, the power module, provides a method for producing a power module according to the manufacturing method and the heat-radiating structure. Power module (1) of the present invention, a ceramic substrate having a dielectric 10, the art and the ceramic substrate a metal member made of a metal or alloy bonded to hard filler material to the surface of 10, 50, the relevant metal parts the surface (50), the acceleration of the powder composed of a metal or alloy with a gas, and a heat-radiating member 40 is formed by the solid state is deposited to as jet on the surface, the heat radiation member 40 inside the heat pipe (60 ) it is buried. ;
