Abstract:
A probe card for simultaneously contacting contact pads being positioned in a zig zag path along a perimeter of a plurality of integrated circuit chips, said integrated circuit chips being arranged along a diagonal axis, said probe card comprising:A) a plurality of substantially parallel linear probes having a tip for contacting said contact pads;B) a structure for fixedly holding said probes, said structure comprising:I) a corrugated surface having individual surfaces corresponding to a projection of said zig zag path along a nonzero angle .beta., each of said individual surfaces fixedly holding at least one of said probes such that said tips are positioned correspondingly to said zig zag path;II) an edge correspondingly shaped to said zig zag path such that said plurality of probes have substantially equal beam lengths.
