DEVICE FOR INSPECTING A PRINTED CIRCUIT BOARD AND A CHIP BY USING THE COMPRESSED AIR FOR OFFERING THE COMPRESSED AIR CORRESPONDING TO TOUCH FORCE APPLIED TO THE PRINTED CIRCUIT BOARD AND THE CHIP TO THE WHOLE SIDE OF THE CHIP WITHOUT PHYSICAL TOUCH

摘要

PURPOSE: A device for inspecting a printed circuit board (PCB) and a chip by using the compressed air is provided to prevent a chip bending phenomenon or a chip separating phenomenon.;CONSTITUTION: A vacuum chuck (100) transfers a PCB (10) and a chip in a vacuum absorption state. A contact unit (200) touches the vacuum chuck through the PCB, the chip, and an inspection pin (212). A compressed air control unit (300) supplies the compressed air to the chip through the vacuum chuck. The vacuum chuck forms a penetrated path and a compressed air area. The penetrated path supplies the compressed air to the chip. The compressed air area supplies the compressed air through the penetrated path.;COPYRIGHT KIPO 2013;[Reference numerals] (AA,CC) Controlled compressed air; (BB) PCB(10) and chip (20)
