Patent ID: 8427183

Claim:
A fully assembled probe card assembly comprising: a drive plate; a probe substrate coupled to said drive plate, said probe substrate comprising a first surface from which a plurality of spring contact structures extend and a second surface opposite said first surface, ones of said spring contact structures comprising contact portions disposed in a pattern that corresponds to terminals of an electronic device to be tested; a wiring substrate comprising an electrical interface connectable to a tester configured to control testing of said electronic device, wherein ones of said spring contact structures are electrically connected to said electrical interface; and flexible electrical connections disposed between and electrically connecting said wiring substrate and said probe substrate; and studs connected to said drive plate and extending toward said probe substrate, each said stud positioned to apply a force to a different region of said second surface of said probe substrate, wherein a first of said studs positioned to apply a force to a first of said regions comprises an actuator that can be activated to selectively push said first of said regions toward and pull said first of said regions away from said drive plate to bend said probe substrate sufficiently to change a shape of said probe substrate.
