Abstract: A printed circuit board test fixture that includes a mounting plate which supports a printed circuit board to be tested is provided. A probe support plate holder, positioned above the mounting plate, mechanically couples to a probe support plate and holds the probe support plate opposite the mounting plate. A base plate is positioned below the mounting plate. At least three alignment sliders are included, with each alignment slider including a guide rail and a runner block slidably coupled to the guide rail. The guide rails are coupled to the base plate. The runner blocks are coupled to the mounting plate to thereby allow for movement of the mounting plate only along an axis perpendicular to a plane of the mounting plate. Multiple balancing sliders coupled to the base plate and positioned at a back end of the printed circuit board test fixture.

Abstract: A test fixture for supporting a printed circuit board while it is undergoing electrical testing is provided. The printed circuit board test fixture includes a substantially planar mounting plate which supports a printed circuit board to be tested. A probe support plate holder, positioned above the mounting plate, mechanically couples to a probe support plate and holds the probe support plate opposite, and substantially parallel to, the mounting plate. A base plate is positioned below, and substantially parallel to, the mounting plate. At least three alignment sliders are included, with each alignment slider of the at least three alignment sliders including a guide rail and a runner block slidably coupled to the guide rail. The guide rail of each of the at least three alignment sliders is coupled to, and extends in an upward direction from, the base plate.
