Printed circuit plate, has metal-coated surface creating thermal dissymmetry between conductive hot and cold zones, and connected by thermal bridges to conductive cold zone

摘要

The plate has conductive cold and hot zones (14A, 14B), and a metal-coated surface (18) creating thermal dissymmetry between the zones. The surface is connected by thermal bridges (16) to the zone (14A) in order to act as energy dissipater. An opening between the zones permits to remove path that takes current in case of carbonization of the plate. An independent claim is also included for a method of protecting a printed circuit plate against overheating of ceramic components assembled on the plate.
