DEFINITION

Classification: 29/827

Beam lead frame or beam lead device:

(under subclass 825) Process of manufacturing either: (1) an integrated circuit having electrical connecting structure in the form of an electrically conductive body having a generally rectangular cross section and wherein the body is mounted in a cantilever fashion to the circuit, or (2) an intermediate article of manufacture utilized to produce electrical connecting structure for integrated circuits consisting of a generally flat electrically conductive strap or band section which has been stamped, cut, or otherwise deformed to produce an open encasing structure provided with a plurality of generally rectangular cross-sectioned inwardly facing bodies designed to be attached to the circuit in a cantilever fashion.
