Abstract

A semi-conductor assembly has semi-conductor, leads in contact with terminals, and a polymer encapsulation around the semi-conductor, electrical connections and part of the leads. The encapsulation provides the protection from the surroundings plus an outer injection-foamed thermoplastic envelope of required external dimensions. Rapidly prodn. is achievd with good protection from surroundings, precise external shape as required, smooth exterior.
