Abstract:
A method for making a buckling beam probe assembly having an upper die, a lower die, and buckling beam probes having probe heads and probe tips, the method comprising the steps of:a. disposing the buckling beam probes in the lower die and the upper die such that the probe tips protrude form the lower die and such that the probe heads protrude from the upper die; b. placing the assembly on a Z-stage located under a top plate of a table, wherein the Z-stage has a planar fiducial surface and wherein the probe tips are in immediate proximity to the planar fiducial surface of the Z-stage; c. pressing the planar fiducial surface against the probe tips such that the probe tips are coplanar with the planar fiducial surface; d. placing an abrasive plate on top of the top plate of the table; e. raising the assembly with the Z-stage until the probe heads contact the abrasive plate; and f. abrading the probe heads to a plane parallel with the planar fiducial surface by rubbing the abrasive plate against the probe heads.
