ABSTRACT:
An apparatus and method for attaching a flip chip configured semiconductor die to a substrate as well as removing the die and replacing it on the substrate with another flip chip-configured semiconductor die by way of an electrically resistive thermal supply circuit that provides heat to soften or melt an electrical connection material of discrete conductive elements connecting the two components, as well as providing heat to release a dielectric underfill material, if present. Methods for designing a thermal supply circuit and are also disclosed. Semiconductor die and substrate configurations incorporating thermal supply circuits as well as thermal supply circuit configurations and design approaches are also disclosed.
