Abstract

PURPOSE:To enhance printing workability and the quality of a printed wiring board by providing a small-sized screen mask frame inside a large-sized screen mask frame and providing a stopper adjusting the position of the small-sized screen frame in the lateral direction thereof to the lateral part of the large-sized screen mask frame. CONSTITUTION:When a medium-sized printed wiring board P2 is sent from the right, the contact part 13b of a stopper 13 is moved in the right direction and fixed by a nut 13a to position the center of the printed wiring board P2 in the left and right direction thereof at the center of the small-sized screen mask frame 2 shown by a broken line. When a small-sized printed wiring board P3 is sent, the contact part 13b is drawn near to the left end shown by a solid line to position the center of the printed wiring board P3 at the almost center of the screen mask frame 2. As a result, the printing of cream solder can be applied to the medium- and small-sized printed wiring boards, which are sent to a position L where the left ends thereof are same to the left end of the large-sized printed wiring board exclusive to a screen printing machine, at the center of a screen and the mounting spaces of cream solder at left and right ends become wide in the same degree to improve workability and the quality of a printed wiring board can be enhanced.
