Disclosed is a technique of test-contacting integrated circuit chips or wafers which incorporate minute solder pads. As shown in Fig. 1, conductive balled or planar probes are incorporated in a contactor board containing appropriate fan-out wiring. In operation, the contactor board is aligned to the product "footprint". The board is then moved toward the product to a point where the solder pads are all deformed to an appropriate height by the probes. A specific total force is then applied and the electrical test commenced.
