910,016. Semi-conductor devices. WESTINGHOUSE ELECTRIC CORPORATION. Oct. 20, 1960 [Oct. 30, 1959], No. 35961/60. Class 37. [Also in Group XXII] In an electrical device comprising a copper, copper alloy, silver, silver alloy, aluminium or aluminium alloy support 12 having a semiconductor device 16 mounted on a central support surface 14 and a peripheral flange 18 with a ferrous metal or ferrous metal alloy ring 26 hermetically mounted thereon to provide a projection extending beyond the flange surface, a header 30 containing an insulating segment 32 with an electrical conductor 34 passing therethrough has a lateral flange 38 heat-welded to the projection on the ring to provide a hermetic enclosure for the component. The member 12 e.g. of brass, has the semi-conductor member 16 soldered to a portion 14 surrounded by the flange 18 with a separating groove 20 and a steel ring 26 is silver alloy soldered in an annular groove 20 in the flange. A ferrous header 30 with conductor 34 through insulator 32 has a flange 38 in contact with the ring and the flange 38 and ring are resistance welded together. The ring may be of generally rectangular section with a rounded, pointed or triangular upper projecting surface. |
