Apparatus and method for testing socket
First Claim
1. A socket testing apparatus comprising:
- a contact unit for obtaining resistance values of respective channels of a calibration PCB and resistance values of respective channels of a socket-installed PCB;
a multiplexer for channeling the respective resistance values from the contact unit so as to output the resistance values of the respective channels in a sequential manner;
a resistance measurement part for storing the respective output resistance values of the multiplexer into a memory, and for calculating differences between the mentioned resistance values and the resistance values of the respective channels of a socket-installed PCB;
a controller for controlling operations of respective elements, and for outputting the output calculation value of the resistance measurement part to a display part; and
the display part displaying an output of the controller.

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).
