Component cooling in communication and measurement equipment - uses metal plate coated with insulating foil which carries components and printed circuit

摘要

Components to be cooled are mounted through an insulating layer on an aluminium plate. The metal plate (3) is coated on its both sides with an insulating foil (5, 6). A printed circuit (9) is produced on the plate one side with components (1) which rest on the other side on the foil (5). The component (1) leads (7) pass through larger holes (8) in the plate (3) and both foils (5, 6) and are soldered to conductors of the printed circuit (9).
