Patent ID: 7649368

Claim:
A method of testing an electronic device, said method comprising: obtaining a contactor comprising a first plurality of terminals and a support structure; obtaining an interposer comprising a substrate, a first plurality of elongate, resilient contact elements extending from a first side of said substrate, and a second plurality of contact elements corresponding to a second side of said substrate, ones of said first plurality of contact elements being electrically connected to ones of said second plurality of contact elements; supporting said interposer with said support structure so that said first plurality of contact elements do not contact said first terminals on said contactor; bringing said interposer into contact with said electronic device; and applying sufficient pressure between said interposer and said electronic device so that said interposer is not supported by said support structure, said first plurality of contact elements contact said first terminals on said contactor, and said first plurality of contact elements and said second plurality of contact elements provide electrical connections from said first terminals on said contactor to a second plurality of terminals on said electronic device.
