Patent ID: 7471094

Claim:
A probe card assembly for contacting a plurality of devices to be tested, each of said devices having a plurality of terminals, said probe card assembly comprising: a mounting structure; a plurality of probe substrates, each of said probe substrates comprising a set of probes disposed on a surface of said probe substrate and configured to contact ones of said terminals of said devices to be tested, each of said probe substrates attached to said mounting structure, said probe substrates disposed adjacent one another such that said sets of probes of said probe substrates form an array of probes; and first moving means for independently moving in a direction that is substantially parallel to at least one of said surfaces of said probe substrate each of at least two of said probe substrates with respect to another one of said probe substrates to align said array of probes with said ones of said terminals of said devices, wherein the first moving means is connected to the probe substrates.
