摘要:
A semiconductor power module (10) comprising one or more semiconductors (4) placed on a substrate (7) is disclosed. The power module (10) comprises a contact formed from a contact pin (6) provided with a plastic sleeve (5) having a central portion (13). Therein the contact pin (6) comprises a longitudinal axis (Y). The plastic sleeve (5) encases a portion of the contact pin (6). The distal portion of the sleeve (5) comprises a plastically deformed zone (8). The sleeve (5) encases the proximal portion of the contact pin (6), wherein the sleeve (5) is continuous from its distal portion to its proximal portion and the proximal portion is in direct contact with the substrate (7) or a structure (9) being in direct contact with the substrate (7).
摘要:
A mold tool (1) is described for molding a semiconductor power module having an electrical contact pin (2) which comprises an electrical contact portion (3) for contacting a substrate (4) with another electrical component. The pin (2) comprises a protruding portion (5) being a top-sided pin connector. The mold tool (1) comprises a first (6) and a second mold die which, when brought together for molding, form a cavity to be filled with a mold compound for encapsulating electrical components of the semiconductor power module, and a recess (7) in the first die 6 which communicates with the cavity within the second die. The recess (7) is filled with a cushion-like soft material (8) into which the top-sided pin connector is pushed thereinto and completely surrounded by the soft material so that a sealing means is formed that prevents any contamination of the electrical contact portion (3) of the pin (2) by the molding compound introduced into the cavity. Furthermore, a method of manufacturing such a semiconductor power module is described.
摘要:
An apparatus comprises a power module (1) and an electric machine (e.g. a multiphase motor of a vehicle), wherein the power module (1) comprises a plurality of components (4) attached to a circuit layer (5) and wherein the power module (1) and the electric machine (e.g. its end bearing plate (2)) are physically connected by an isolation layer (7), the isolation layer (7) electrically insulating the power module (1) and the circuit layer (5) from the electric machine. The power module (1) is thus an integral part of the electric machine. The circuit layer (5) may be a lead frame. The plurality of components (4) may be attached to the circuit layer (5) by sintering or soldering. The isolation layer (7) may be an epoxy resin filled with thermally conductive fillers. An encapsulation layer may be provided, by filling a resin (12) within additional resin walls (dam) (11). A multi-terminal socket (15) with a plurality of terminals (13) mounted in a plastic holder (14) may be provided, configured perpendicular to the circuit layer (5).
