Abstract

1,258,488. Component assemblies. ULTRA ELECTRONICS Ltd. 14 Sept., 1970 [18 Oct., 1969], No. 51259/69. Heading H1R. A method of providing a heat sink for electronic components 9, 11 mounted on printed circuit boards 8 comprises placing the board with components in a vacuum forming jig, heat treating a sheet of plastic metal 10, such as aluminium, steel or titanium, and vacuum forming the plastic metal to conform to the general outline of the components on the board. On removal, the plastic metal is covered with a foamed thermo-plastics material. The plastic metal 10 is in good thermal contact with the chassis 1 which may be artificially cooled.
