Abstract
Abstract There is disclosed a circuit change pin and a circuit board assembly. The circuit change pin is a termination post which is held in a compliant electrically insulating base. The base is made from a heat-recoverable material which is preferably a poly(aryl ether ketone). When the circuit change pin is used in conjunction with a printed circuit board, there is then a circuit board assembly.
