Abstract:
The power module of the invention includes a power element, a metal base for dissipating heat from the power element, a lead frame electrically connected to electrodes of the power element, and a resin enclosure that encapsulates the power element so that one surface of the metal base and a part of the lead frame are exposed from the enclosure. The resin enclosure of the power module includes: a body portion in which the power element and a part of the lead frame are placed, and at a bottom surface of which the one surface of the metal base is exposed; and a rib portion which is placed on the bottom surface of the body portion so as to surround an outer periphery of the metal base, and is formed to protrude from the bottom surface of the body portion in a direction perpendicular to the bottom surface.

Claim (Index 19):
A power module manufacturing method of manufacturing the power module of  claim 1 , wherein, in a rib-end forming part of the mold at which the end of the rib portion overhanging from the bottom surface of the resin enclosure is to be formed, a plurality of pin openings in which for pins for ejecting the resin enclosure are to be inserted are formed;\n said power module manufacturing method comprising: a step of placing an intermediate-product assembly which comprises the power element, the metal base and the lead frame, in a mold so that the metal base is in contact with its metal-base placement part and a part of the lead frame is exposed from the mold; a step of forming the resin enclosure by injecting a transfer-mold resin into the mold in a state in which the pin openings are closed with the pins; and a step of forming depressions in the rib portion in such a manner that, at the time the resin enclosure is ejected from the mold, the pins are inserted beyond the pin openings up to a depth that is larger than a width in a transverse direction of the end of the rib portion, so that the pins push cut the rib portion of the resin enclosure.
