Patent ID: 7323895

Claim:
A pogo probe card for probing a test device comprising: (a) a laminate board including a set of auxiliary guard traces interposed between first and second dielectric layers, said board forming an opening and having a first major surface; (b) a plurality of probing devices for probing a plurality of probing sites on a test device, each probing device including an elongate probing needle and an electrical connection point electrically connected to said probing needle, said probing devices being mounted to said first major surface in radial arrangement about said opening and extending through and beyond said opening, so that said probing needles terminate in a pattern suitable for probing said sites; (c) a plurality of pogo pin receptive pad sets; (d) a set of first conductors for electrically connecting each pad set to a said auxiliary guard trace; and (e) a second conductor for electrically connecting a said electrical connection point to a said pad set.
