PURPOSE: A bare chip test device of a pin-type multi-chip module reduces damage to or abrasion of a pin insertion hole. CONSTITUTION: A pin-type multi-chip module includes a printed circuit board (2), an upper plate (4), and a chip block (6). The printed circuit board is fixed on a lower through hole (1a) formed on the center of a base plate (1). The lower parts of multiple conductive metal rods (3) with a pin insertion hole at the upper side are detachably fixed to the printed circuit board in the vertical direction. The upper plate is formed above the printed circuit board, is fixed to the base plate by a vertical support rod (4a), and includes an upper through hole (4b) at the center. The chip block is fixed on the upper through hole of the upper plate to pass through vertically. The chip block inserts or mounts multiple bare chips (5) to make a vertical connection pin inserted into the pin insertion hole of the conductive metal rod protrude to the lower side. |
