Abstract
Techniques for electrically testing a flip-chip assembly during its manufacture include a flip-chip assembly having an integrated circuit (IC) die and an IC package substrate. The IC package substrate is placed on a substrate part holder that includes test sockets and heating elements. The IC die is then placed on the placed IC package substrate. The placed IC die and IC package substrate are aligned such that conductive contacts are formed from conductive bumps and pads deposited on the surface of the IC die and IC package substrate. While the bumps and pads are in conductive contact, but prior to attachment, the flip-chip assembly is electrically tested. If the flip-chip assembly passes electrical testing, the conductive contacts may be attached by the heating elements on the substrate part holder, such as in a solder reflow process when the bumps are made from solder.
