Patent ID: 8492739

Claim:
A probe inspection apparatus, comprising: a base plate; a stage placed over the base plate and comprising a plurality of back light modules that supply a rear surface of a substrate with at least one of light or heat, the substrate being seated in the stage; a probe pin configured to electrically come into contact with circuit patterns formed in the substrate and measure electrical properties of the circuit patterns; a probe head configured to support the probe pin and move in an X or Y axis; and an upper light source unit mounted on one side of the probe head and configured to irradiate light to the circuit patterns, wherein the upper light source unit comprises light source arrays, a color filter plate placed on the light source arrays and configured to downwardly reflect light generated by the light source arrays, the color filter plate is applied as one color filter layer in an actual liquid crystal module state, a light source support track into which the color filter plate is inserted and on which the light source arrays are mounted, and a light emission hole configured to introduce the reflected light to the circuit patterns.
