Abstract
Probe pin arrangements in a vertical-type probe card assembly for an automated test equipment (ATE) are disclosed. In some embodiments, one or more additional conductive regions are provided in between adjacent probe pins. The additional conductive regions may reduce spacing between probe pins connected to adjacent probe card pads, and may in turn reduce or adjust inductance between the two probe cards pads to provide improved signal impedance matching or lower power impedance. In one embodiment, the additional conductive region is a short probe pin. In another embodiment, the additional conductive region is a protrusion on a vertical probe pin.
