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 1):
A power module with a built-in power device and double-sided heat dissipation, comprising:\n a first base plate, wherein the first base plate comprises a first organic insulating base material and a first electrical insulating heat dissipation body embedded in the first organic insulating base material, a first metal layer thermally connected to a first side of the first electrical insulating heat dissipation body is formed at an outer side of the first base plate, a second metal layer thermally connected to a second side of the first electrical insulating heat dissipation body is formed at an inner side of the first base plate, and the second metal layer is patterned; and a second base plate, wherein the second base plate comprises a second organic insulating base material and a second electrical insulating heat dissipation body embedded in the second organic insulating base material, the first electrical insulating heat dissipation body and the second electrical insulating heat dissipation body overlap with each other in a thickness direction of the first base plate, a third metal layer thermally connected to a first side of the second electrical insulating heat dissipation body is formed at an outer side of the second base plate, and a second side of the second electrical insulating heat dissipation body is formed with a fourth metal layer thermally connected to the second electrical insulating heat dissipation body; and wherein the fourth metal layer is formed with a concave power device accommodating space, and the built-in power device is arranged in the concave power device accommodating space, and wherein the second organic insulating base material comprises prepregs and organic insulating medium layers sequentially and alternately arranged.
