ABSTRACT:
An electrical component assembly (10), comprising a rectifier bridge, utilizes a protective cover (30) for mechanical protection of semiconductor diode dies (11, 12) mounted on an aluminum heat sink support carrier (16). Channels (37, 37B) with effective openings (40, 40A) therein are provided in a top surface (38) of the protective cover to facilitate applying an environmental sealing materail (45) through said channels and openings to the semiconductor diode dies of the electrical assembly as well as to various critical electrical interconnections (48) in the electrical assembly. By utilizing the mechanically protective cover to also provide for guiding the application of an environmental sealing material for the electrical assembly, extensive fixturing in providing a desired electrical assembly is minimized, the assembly is rendered more readily manufacturable, and protection of the assembly is provided even during the step of dispensing the sealing material.
