Abstract:
1. Apparatus for making temporary electrical contact to a linear array of contact pads on a device under test, the apparatus comprising: a set of vertical probes, wherein each of the vertical probes includes a base section and a tip section, wherein for each of the vertical probes, the corresponding base section and tip section are at opposite ends of the corresponding vertical probe; wherein each of the tip sections includes a tip contact surface for making electrical contact to the device under test; wherein the tip sections of the vertical probes are disposed such that the corresponding tip contact surfaces are disposed along a straight contact line; wherein the base sections of the vertical probes are disposed in a two-dimensional base array having at least two rows parallel to the contact line, wherein all rows of said base array are disposed on the same side of said contact line; wherein a thickness of the base sections along the rows is substantially larger than a center to center spacing of adjacent tip contact surfaces along the contact line.
