Patent ID: 7592565

Claim:
An apparatus for positioning and bonding probes to a substrate of a probe card, comprising: a stage unit on a working table, the stage unit being movable in three dimensions and supporting the substrate; a microscope coupled to a first guide member positioned at a first portion of the working table and placed above the stage unit; a probe fixing unit mounting on a supporting member in such a configuration that the probe fixing unit moves on the supporting member vertically to the working table, an end portion of the probe fixing unit to which a probe is fixed being interposed between the microscope and the stage unit so that the probe makes contact with the substrate at a connected portion thereof; and a light source unit movably coupled to a second guide member positioned at a second portion of the working table, a laser being emitted to the connection portion of the substrate from the light source unit, to thereby bonding the probe to the substrate at the connection portion of the substrate, wherein the probe fixing unit includes: a bracket moveably secured to the supporting member and including a pair of plates and a shaft interposed between the plates; a pincette moveably secured to the bracket and including a head portion secured to the bracket and a gripping portion opposite to the head portion to which the probe is fixed, the head portion of the pincette being secured to the shaft in a space between the plates; and a controller for controlling an open angle of the pincette, the controller positioned at a side of the pincette and applying a pressure to the pincette.
