Abstract
Multi-chip modules provided with a pin array may, under close scrutiny, display certain defects that may cause reliability problems. The presence of even one such defect necessitates the scrapping of the module. A method of salvaging the module is described, wherein the module is reworked by the method comprising the steps of applying a shearing force against the pins. During which the module is exposed to a temperature at or above that which is necessary for softening the braze material to remove the pins; polishing the surface of the module including the pads; evaporating the new pads; and attaching new pins to the pads.
