Abstract:
1. An apparatus, comprising: a probe card interface assembly, comprising a probe chip assembly mounted to the probe card interface assembly, the probe chip assembly comprising a probe chip substrate having a probing surface and a mounting surface opposite the probing surface, and a plurality of probe springs extending from said probing surface for providing electrical connections to at least one integrated circuit device on a semiconductor wafer, said probe springs having electrical connections to a plurality of standard connections on the mounting surface, said standard connections corresponding to said pattern of electrical connections on said bottom surface of said motherboard substrate; wherein a probe chip assembly mounting reference plane is defined by at least three points between the lower surface of the motherboard substrate and the semiconductor wafer, wherein the probe chip assembly mounting reference plane is adjustable to be coplanar to the probe chip assembly mounting surface of the probe card interface assembly based on measured data of the probe card interface assembly.
