Patent ID: 7764075

Claim:
A probe card assembly for providing electrical connection between an integrated circuit tester and a wafer, the probe card assembly comprising: an interface board comprising a first rigid substrate and a plurality of first electrical contacts arranged to make electrical connection to the integrated circuit tester when the probe card assembly is coupled to the integrated circuit tester; a probe board comprising a second rigid substrate, a plurality of probes disposed on a surface of the second substrate and arranged to make electrical connections to the wafer when the probe card assembly is brought into contact with the wafer, and a plurality of first electrical paths interconnecting first ones of the probes to corresponding ones of the first electrical contacts of the interface board; and a flexible cable connected at a first end to the interface board and connected at a second end to the probe board, the flexible cable comprising a plurality of second electrical paths arranged at the first end to make electrical connection to the integrated circuit tester when the probe card assembly is coupled to the integrated circuit tester and electrically connected at the second end to second ones of the probes.
