Abstract
A probe card includes a probe, a circuit board, a first reinforcing plate and a second reinforcing plate. The probe makes contact with an object. The circuit board is electrically connected to the probe. The first reinforcing plate has a first tap and a second tap for providing an adjustable gap between the first reinforcing plate and an upper surface of the circuit board. The second reinforcing plate is positioned under a lower surface of the circuit board. The second reinforcing plate combined with the second tap to form an adjustable gap between the second reinforcing plate and a lower surface of the circuit board.
Claims8
A probe card comprising:
- a probe making contact with an object;
- a circuit board electrically connected to the probe;
- a first reinforcing plate having a first tap and a second tap for providing an adjustable gap between the first reinforcing plate and an upper surface of the circuit board;
- a second reinforcing plate positioned under a lower surface of the circuit board and combined with the second tap to have an adjustable gap between the second reinforcing plate and the lower surface of the circuit board;
- and
- a spacing member combined with the second tap,
- wherein the circuit board has an inserting hole at a position corresponding to the second tap and the spacing member is positioned in the inserting hole,
- wherein the first tap is formed at an edge portion of the first reinforcing plate and the second tap is formed at a central portion of the first reinforcing plate.
