Abstract: A power module, including: a chip, a package baseplate, a ceramic baseplate, and a plastic package body. The chip is disposed on the ceramic baseplate, the package baseplate is disposed on a surface that is of the ceramic baseplate and that is away from the chip, and an area of the package baseplate is greater than an area of the ceramic baseplate. The package baseplate includes at least one protrusion structure which is located on a surface that is of the package baseplate and that is close to the ceramic baseplate, and projection of the at least one protrusion structure does not overlap projection of the ceramic baseplate in a thickness direction of the chip. The chip, the ceramic baseplate, and the surface that is of the package baseplate and on which the at least one protrusion structure is disposed are disposed in the plastic package body.

Abstract: A power module includes: a first metal brazed substrate; a chipset disposed on the first metal brazed substrate, where the chipset includes at least two chips; and a clip, where the clip covers a side, away from the first metal brazed substrate, of the chipset. Each connecting unit is electrically connected to a corresponding chip. Every two adjacent connecting units are connected along a first direction through a body. Each connecting arm is arranged with respect to two adjacent chips in the chipset. The connecting arm is connected to the first metal brazed substrate. A shortest distance between the connecting arm and one of the two adjacent chips is a first shortest distance, a shortest distance between the connecting arm and the other of the two adjacent chips is a second shortest distance. A difference between the first shortest distance and the second shortest distance falls within a preset threshold.
