Abstract
A probe card includes a conductive body, an insulation block, and a plurality of conductive microsprings. The insulation block covers at least one side of the body and at least partially encloses the microsprings. A first end of each microspring is connected to the conductive body and a second end is exposed from the insulation block. In operation, the probe card is moved onto one or more semiconductor devices to be tested. As the probe card is moved toward the semiconductor devices, the second ends of the conductive microsprings come into contact with contact pads on the semiconductor devices. The insulation block encloses the microsprings, which prevents the microsprings from buckling or making contact with each other. As a result, the probe card produces fewer false positives and false negatives during the testing process.
