Abstract:
Disclosed is a power module with built-in power device and double-sided heat dissipation and a manufacturing method thereof. The power module includes a first base plate including a first organic insulating base material, a first electrical insulating heat dissipation body, a first metal layer, and a patterned second metal layer; a second base plate including a second organic insulating base material and a second electrical insulating heat dissipation body. A third metal layer thermally connected to a side of the second electrical insulating heat dissipation body is formed at the outer side of the second base plate. A fourth metal layer thermally connected to the second electrical insulating heat dissipation body is formed at another side of the second electrical insulating heat dissipation body. The fourth metal layer is formed with a concave power device accommodating space, and the power device is arranged in the accommodating space.

Claim (Index 9):
The manufacturing method for the power module according to  claim 8 , wherein the step of providing the first base plate comprises:\n providing the first organic insulating base material with a first through window and first base material metal layers arranged on two opposite surfaces of the first organic insulating base material, wherein the first organic insulating base material comprises an organic insulating medium layer and a prepreg sequentially and alternately arranged between the two first base material metal layers; placing the first electrical insulating heat dissipation body with two opposite surfaces respectively formed with the first heat dissipation metal layer in the first through window; performing hot pressing on the first base plate; sequentially forming a first base copper layer and a first electroplated thickened copper layer on two opposite surfaces of the first base plate, respectively, wherein, the first base material metal layer, the first heat dissipation metal layer, the first base copper layer, and the first electroplated thickened copper layer located at a first surface side of the first base plate form the first metal layer, the first base material metal layer, the first heat dissipation metal layer, the first base copper layer, and the first electroplated thickened copper layer located at a second surface side of the first base plate form the second metal layer; and patterning the second metal layer.
