Abstract:
A buckling beam probe assembly comprising:a) a lower die; b) an upper die disposed planar parallel with and spaced apart from the lower die with a distance; and c) a plurality of buckling beam probes each comprising a probe tip, a flexible middle section and a probe head having a substantially uniform head section and a flat head top surface, wherein said distance is greater than the length of each said flexible middle section, said probe heads and said probe tips of said buckling beam probes are guided within said upper die and said lower die respectively in a probe floating direction such that length differences of said buckling beam probes are abrasively removable from said probe heads by aligning said probe tips in a rigid fiducial planar surface substantially parallel to said upper die.
