Abstract

910,249. Semi-conductor devices. STANDARD TELEPHONES & CABLES Ltd. May 19, 1961, No. 18471/61. Class 37. [Also in Group XXII] In making an hermetically sealed enclosure for a semiconductor device with a base and a cap, each having a flange of cold - weldable material, only one of the flanges is backed with a permanently attached collar of non- deformable material and pressure is applied between the collar and the other flange to cold - pressure weld the flanges. A copper base 4 with a peripheral flange 6, of a semi - conductor rectifier, is force-fitted on the splines 2 of a steel hexagonal collar 1 so that the upper surface of a ridge 3 thereon contacts the underside of the flange. A silicon element 8 soldered between molybdenum discs 9, 10 is soldered in a well 7 in the base 4 and a flexible lead wire 12 with melted solid ends is soldered to the disc 10. A cap 14 with a copper peripheral flange 16 is placed on the base with the flanges 6, 16 in contact and the wire 12 enters a cavity 21 in a copper member 20 attached to a nickel-iron insert 19 secured in a glass ring 18 in a steel cylinder 17 brazed to a copper member 15. The assembly is placed in a recessed block 26 and an annular rod 27 is caused to cold weld the flanges. Excess flange material is cropped, the member 20 is crimped on the lead 12 and a flexible copper lead 24 is crimped and soldered in the member 20.
