Abstract: Methods for repacking copper wire bonded microelectronic die (that is, die having bond pads bonded to copper wire bonds) are provided. In one embodiment, the repackaging method includes the step or process of obtaining a microelectronic package containing copper wire bonds and a microelectronic die, which includes bond pads to which the copper wire bonds are bonded. The microelectronic die is extracted from the microelectronic package in a manner separating the copper wire bonds from the bond pads. The microelectronic die is then attached or mounted to a Failure Analysis (FA) package having electrical contact points thereon. Electrical connections are then formed between the bond pads of the microelectronic die and the electrical contact points of the FA package at least in part by printing an electrically-conductive material onto the bond pads.
