Abstract:
1. A probe for engaging a conductive pad, said probe comprising: a. a probe contact end for receiving a test current; b. a probe retention portion below said contact end; c. a block holding said retention portion; d. a probe arm below said retention portion; e. a probe contact tip below said arm; and f. a generally planar self-cleaning skate disposed perpendicular below said contact tip having a generally square front end, a generally round back end and a generally flat middle section therebetween, wherein said conductive pad of generally convex shape and having a granular non-conductive surface layer of debris moves to engage said skate, whereby an overdrive motion is applied to said conductive pad thereby causing said skate to move across said conductive pad to scrub non-conductive debris from said conductive pad and displace said debris along said skate and move said debris near said skate round back end to a position on said skate that is away from said conductive pad.
