Zusammenfassung: | The invention relates to a metal Clip welded power module for a vehicle. The vehicle power module welded by the metal Clip comprises a shell assembly, a chip assembly and a heat dissipation column. The shell assembly comprises an outer shell and a heat dissipation substrate. The chip assembly comprises a ceramic copper-clad plate, a power chip, a bonding resistor and a Clip connecting piece. The Clip connecting piece comprises an extension part, a welding part, a notch and a chip welding part. The connecting part between the welding part and the extending part is in a step shape, the height of the welding part is lower than that of the extending part, the chip welding part is located on the end face, facing the power chip, of the extending part, and the chip welding part is a rectangular protrusion extending in the direction of the power chip. And the edge of the chip welding part is arranged in a fillet manner. The connection between the power chip and the ceramic copper-clad plate is realized by arranging t |
