Abstract: A needle assembly of probe card includes a plate and needles formed therein for enhancing an assembly characteristic and productivity and increasing an exact and reliable characteristic test. The plate is provided with holes that are formed with an insulating film on an inner side surface thereof. One side end surface of the needle adheres on an inner side surface of the hole, another side end surface thereof is spaced from an inner side surface of the hole, and a vertical thickness of the other side of the hole is formed thinner than the plate so as to have a space in which the other side can vertically move upwardly and downwardly. The plate and the needle are integrated.

Abstract: A needle assembly of probe card includes a needle guide plate and needle plates formed therein for enhancing an assembly characteristic and a productivity and increasing an exact and reliable characteristic test. The needle guide plate is provided with needle movable holes that are formed with an insulating film on a circumferential surface thereof. One side end surface of the needle plate adheres on an inner side surface of the needle movable hole, another side end surface thereof is spaced from a circumferential surface of the needle movable hole, and a vertical thickness of the other side of the needle movable hole is formed thinner than the needle guide plate so as to have a space in which the other side can vertically move upward and downward. The needle guide plate and the needle plate are combined into one body.
