ABSTRACT:
A simplified method of manufacturing an electrothermal fuse includes the steps of screening conductive epoxy onto fuse link termination pads, placing a metal alloy fuse link into the conductive epoxy on the termination pads, curing the conductive epoxy, applying deoxidant, applying encapsulant, and curing the encapsulant. The resultant fuse of the preferred embodiment comprises a substrate, termination pads, conductive epoxy interconnects, a solder type fuse link, liquid deoxidant and encapsulant.
