Abstract
A rolling contactor for providing electrical signal communication between a component terminal and a support structure for the rolling contactor, including an electrically conductive circular roller for rolling across the termination surface of a device under test (DUT), at least one electrically conductive circular spool, a support axle adapted to pass axially through the holes formed in the roller and the spool, an electrically conductive axle bracket adapted to support the axle to allow the roller surface to rotate and press against the termination surface of the DUT, an electrically conductive brush extending from the axle bracket to contact the spool, and an electrically conductive elongated spring arm extending between the axle bracket and the support structure, to complete the electrical path between the termination surface of the DUT, the roller surface and the spool.
