Abstract
A testing head for microstructures is presented. The testing head includes a top guide plate and bottom guide plate, separated by an air gap. Each of the plates include respective guide holes for accommodating a contact probe having a contact tip that is arranged to mechanically and electrically contact a contact pads on a device under test. The contacting tip of the testing head has a non-zero pitch angle (&agr; ) relative to the contact pad, and “scrubs” the pad as the device under test is drawn against the contacting tip, causing the contact probe to bend within the air gap.
