Patent ID: 6876211

Claim:
A printed circuit board test fixture comprising: a substantially planar mounting plate which supports a printed circuit board to be tested; a probe support plate holder, positioned above the mounting plate, which mechanically couples to a probe support plate and holds the probe support plate opposite, and substantially parallel to, the mounting plate; a base plate positioned below, and substantially parallel to, the mounting plate; at least three alignment sliders, 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 coupled to, and extending in an upward direction from, the base plate, the runner block of each of the at least three alignment sliders coupled to the mounting plate, thereby allowing for movement of the mounting plate only along an axis perpendicular to a place of the mounting plate and also preventing the mounting pate from tilting when test points on the printed circuit board are urged against test probes on the probe support; and a plurality of balancing sliders coupled to the base plate and positioned at a back end of the printed circuit board test fixture.
