Abstract

PURPOSE: To widen the mounting intervals of probe pins, by connecting measuring probe on the printed board bidirectionally and locating in zig zag the measuring probe, in the conductivity inspection of the printed board having the through-hole pads arranged in grid shape.
CONSTITUTION: The measuring probe pins 2 are located so that they contact to the printed board 3 from the both sides, and the pins 2 are driven with the press mechanism 4. Further, the measuring probe pins 2 are located in zig zag to the through-holes 8 and mounted on the pin board 1. Respectively, one driver and receiver in the driver/receiver section 15 is selected from the command instruction from the electronic computer 13, a current flows to the printed board 18 through the probe pins 17 in the prober section 16 to judge the presence of miswiring. The said receiver is fixed, it is repeated at the final address while sequentially adding the driver selection address by +1, the address of the driver judged as the presence of wiring is transferred to the electronic computer 13, it is compared with the wiring pin address information from the conductivity tester 12, and the short circuit and open wire of the printed board 18 can be detected.
