Abstract:
A rework process includes attaching a first bond head to a first semiconductor package. The contact pads of the first semiconductor package are bonded to contact pads of a second semiconductor package by solder joints. The rework process further includes performing a first local heating process to melt the solder joints, removing the first semiconductor package using the first bond head, and removing at least a portion of solder from the contact pads of the second semiconductor package.
