Abstract:
Recesses (72), surface contours, contact tip modifications (52, 56), and/or other methods of ensuring pressure between a bottom surface (50) of a test plate (5) and top surfaces (52) of electrical contacts (18) are employed to enhance cleaning of the top surfaces (52) of the electrical contacts (18) to promote reliable measurements of DUTs (14).
