Abstract
An automotive alternator rectifier bridge comprising a pair of generally flat heat-conducting laminated bases each having a central layer of aluminum with layers of copper bonded to the opposite surfaces thereof. A plurality of first diodes have their cathodes solder-connected to one surface of one of the bases. The anodes of a plurality of second diodes are solder-connected to one surface of the other of these bases. Each diode is constituted by a discrete semiconductor chip having a metallic layer in ohmic contact with one face thereof and each diode is secured to one of the bases by having its metallic layer soldered to the laminated base. Electrical conductors are solder-connected to the anodes of the first diodes and to the cathodes of said second diodes and extend generally parallel to the bases for connection to automotive alternator terminals. Methods of fabricating these bridges are also described.
