ABSTRACT:
An integrated circuit probe card comprises a circuit board and a plurality of probes provided with a first pitch between them. The circuit board is constituted by a plurality of laminates and comprises an upper surface and a bottom surface a plurality of testing pads provided on the upper surface with a second pitch between them. Besides, the circuit board can further comprise a plurality of electronic devices provided on the upper surface for processing signals. The plurality of testing pads are connected to the bottom surface by the use of the plurality of conductive wires. The plurality of probes are provided wits a first pitch and connected to the conductive wire on the bottom surface of the circuit board, wherein the first pitch is smaller than the second pitch.
