Printed Circuit Board Rom Writing and Function Testing System

摘要

The present invention is completed by a surface-mount printed circuit continuously supplied to a substrate (PCB) on a PCB-ROM writing and function test of the system to perform a ROM writing and function tests.; The present invention system and the first transfer device for transferring the first conveyor, and a buffer stacker, and the PCB conveying to the first conveyor which PCB is temporarily stored in multiple stages for transporting the PCB flowing from the front-end process to test the elevator, the by mounting the PCB carried by the first transfer device performs ROM writing and function tests, and a test capable of moving up and down the elevator, is provided inside the test elevator, of the plurality having a contactor for each contact with a PCB and electrically a second transfer device for transferring the test portion and, PCB and the electrical signal the controller to determine the yangbul and receive marking means for displaying a defect mark on the PCB is determined as defective, and all PCB tested, to a second conveyor and, a second conveyor, and the PCB is determined as defective during the PCB carried by the second conveyor 2 which conveys the PCB carried by the transfer device to the stacker NG It consists of the NG stacker that material.
