| abstract | (57) [Abstract] [Purpose] To provide a test board for an IC tester including a circuit for detecting and displaying a contact failure between a pin card and a test board. [Structure] The contact failure detection circuit of the test board 2 includes a switch 7 for controlling ON / OFF of the circuit, an inverter 8, and a light emitting diode 9 with a decoder for displaying a contact failure detection result. Switch 7 is on when checking for contact and off when testing the DUT 6 electrically. By setting the output of the driver 3 to a high level signal and turning on the switch 7, the input of the light emitting diode 9 with a decoder is at a low level if the pogo pin 4 and the gold pattern 5 are in contact, and if there is a contact failure. High level. A defective contact pin can be easily found by displaying the decoder-equipped light emitting diode 9 which decodes and displays the input state. |
