An IC package design and method of making the package design that provides anti-bridging between metal leads. The anti-bridge IC package design extends bottom covercoat material out onto the leads a sufficient distance to prevent solder bridging that typically takes place in cup regions of gull wing shaped leads. A further feature of the invention is to provide a method of applying covercoat material to the IC and the leads in the same process step. A resilient material wheel and related manufacturing equipment is used to apply a single covercoat material, like epoxy, in a single step that serves as both the bottom covercoat and lead anti-bridge coat for the IC.

Integrated circuit anti-bridging leads design

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.
