Patent ID: 7285973

Claim:
A method of standardizing a test head assembly to a plurality of different integrated circuit dice, comprising: defining a predetermined configuration of contact positions comprising contact positions corresponding to a bonding pad footprint for each integrated circuit die of the plurality of different integrated circuit dice; fabricating a test head assembly having an arrangement of probe holes defined by the predetermined configuration of contact positions, each probe hole extending from a first end associated with a contact position of the predetermined configuration of contact positions to a corresponding second end; and for each of the different integrated circuit dice, defining a bonding pad footprint according to the predetermined configuration of contact positions; and selectively populating the probe holes of the test head assembly with contact probes extending through corresponding second ends of the probe holes to enable an electrical connection between bonding pads of the integrated circuit die defined according to the bonding pad footprint and corresponding contacts of a plurality of contacts, wherein the corresponding contacts are defined according to the bonding pad footprint; wherein the bonding pad footprint defined for each of the different integrated circuit dice is different from the bonding pad footprints of the other integrated circuit dice in the plurality of different integrated circuit dice.
