Abstract

1,261,378. Semi-conductor devices. INTERNATIONAL RECTIFIER CO. (GREAT BRITAIN) Ltd. 8 July, 1969 [8 July, 1968], No. 32467/68. Heading H1K. In a method of encapsulating an electrical component the component 2 has a layer 3 of varnish applied to it and is then coated with a layer 4 of a flexible compound after which it is embedded in an outer rigid casing 5 applied in a mould, the flexible compound where it coats the leads 1 of the component projecting through this outer casing. The flexible compound may be sprayed on as a solution of silicone rubber in toluene and the outer moulded easing may be of epoxy resin.
