Title: CIRCUIT CARRIER, POWER ELECTRONICS ASSEMBLY HAVING A CIRCUIT CARRIER
Abstract:
The invention relates to a circuit carrier (ST) for holding at least one electrical power component (BE), comprising: a heat sink (KK) for holding and cooling the power component (BE), which heat sink has a surface (OF1); a copper layer (KS) for mechanically connecting the heat sink (KK) to at least one copper plate (KP), wherein the copper layer (KS) consists of copper or a copper alloy and is applied to the surface (OF1) of the heat sink (KK) by cold gas dynamic spraying or by sintering; at least one copper plate (KP) for mechanically and electrically connecting the power component (BE) to the copper layer (KS), wherein the copper plate (KP) consists of copper or a copper alloy and is arranged directly on a surface (OF2) of the copper layer (KS) facing away from the heat sink (KK) and is connected to the copper layer (KS) in a planar, mechanical, and electrically conductive manner.
