CIRCUIT BOARD CHECKER AND CIRCUIT BOARD CHECKING METHOD

摘要

A circuit board checker for electrically checking a circuit board by electrically connecting electrodes to be checked and provided on the circuit board to checking electrodes provided in a pattern corresponding to the electrodes to be checked through an anisotropically conductive sheet. Upper and lower board clampers are arranged above and below the circuit board and provided on upper and lower base sheets supported by posts of post-planted plates. The positions of the upper and lower supported points at which the circuit board is supported by the posts are different from one another on a projection in the direction of the thickness of the upper and lower board clampers as viewed from above. Thus, even if the sizes of the electrodes to be checked are small, the circuit board can be checked with high reliability. A circuit board checking method for such checking is also disclosed.
