A probe card assembly for providing electrical interconnection between a
semiconductor device to be tested and a test system is provided. The
probe card assembly includes a plurality of probes supported by a support
substrate, each of the plurality of probes including an end portion
extending away from the support substrate. The end portion is configured
to be electrically connected to a semiconductor device to be tested. The
probe card assembly also includes a dielectric sheet positioned between
the support substrate and the end portion of the plurality of probes such
that the probes extend through apertures defined by the dielectric sheet.
