Patent 7449902 was granted and assigned to Powerchip Semiconductor on November, 2008 by the United States Patent and Trademark Office.
A probe apparatus and a probe system are provided. The probe apparatus uses a larger printed circuit board to dispose a plurality of testers. The layout of each of the testers on the circuit board is modified accordingly, such that more number of the testers can be disposed on the circuit board and the pin count of the probe apparatus is increased. In addition, the probe apparatus can be installed in the test tool. Accordingly, the testing efficiency of the present test tool can be substantially promoted and the cost of the overall testing can be effectively reduced.
