Abstract
A method and apparatus for printing an electronic circuit on a board by screen printing. A board to be printed is transported from a supply/discharge station to a positioning station and then to a printing station and is returned to the supply/discharge station. At the positioning station spaced from the printing station, positioning of the board is effected by an image processor and an XY.theta. table. The board thus positioned is transported to the printing station while the board is kept in the positioned state. At the printing station, a screen printing is effected on the thus correctly positioned board.
