Printed circuit i.e. backplane circuit, for controller of aircraft, has protected conductive track comprising nominal cross-section and throat of reduced cross-section less than nominal cross-section defining fuse segment on protected track

摘要

The circuit has a monolayer or multilayer insulating support and a conductive track (10), where the protected track comprises a nominal cross-section and a throat (24) of reduced cross-section less than the nominal cross-section defining a fuse segment on the protected track. Width of the throat of the protected track is lower than nominal width of the protected track, where the throat comprises a set of conductive strips. An independent claim is also included for a method for protecting an electronic apparatus.
