  • Patent number: 6792376
    Abstract: An apparatus and a method for testing a socket are disclosed. The resistance values of the contactor pins of the socket can be precisely measured, and the measurement is made automatic so as to decrease the expense and manpower. The method includes the following steps. That is, a calibration PCB is formed into a closed circuit, and all the resistance values forming a closed circuit loop for respective channels are extracted and stored (first step). A socket-installed PCB is formed into a closed circuit, and all resistance values forming a closed circuit loop for respective channels are extracted and stored (second step). Differences between the resistance values of the respective channels of the calibration PCB and the resistance values of the respective channels of the socket-installed PCB are calculated (third step). The differences thus calculated are displayed to a screen for the respective channels (fourth step).
