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.
