Abstract

959,373. Transistors. GENERAL ELECTRIC CO. Ltd. May 2, 1961 [May 5, 1960], No. 15943/60. Heading H1K. Good thermal contact between a relatively massive metallic member and a metallic part of an envelope enclosing a transistor, comprising a semi-conductor body mounted on the member which also acts as a base electrode, is obtained by deforming the envelope after assembly. Semi-conductor wafer 1 is mounted in a dished portion 7 of a metallic member 6, of tinned nickel, which is welded at one end to an upstanding tag 10 of a copper cup 9, and at the other end to wire 20 welded to a tag 11 on the cup. The cup 9 rests on a glass disc 17 sealed into a lower housing part 15, also of copper, and wire 20, and collector and emitter wires 19 and 18 are sealed through disc 17. The copper upper housing part 22 is placed over the assembly and flanges 16, 23 are cold pressure welded together in a dry air atmosphere, the inward flow of metal during welding deforming the housing into good contact with cup 9 and securing the latter in position. In a modification (Fig. 4, not shown), cup 9 is replaced by a copper disc spaced from the glass disc 17 by a wire ring so that on deformation of the housing the copper disc bites into the wall of the housing.
