Abstract

A device and method for burn-in of bare chips prior to assembly into a multichip module. Each die to be tested is positioned with its I/O pads positioned to face an interconnection burn-in test substrate which may be a silicon circuit board. Each die is temporarily electrically connected to the substrate by a deformable solder bump.
