ABSTRACT:
When a printed circuit board is inspected and determined to have an insufficient amount of printing of a print pattern, the printed board is returned to a screen-printing apparatus so that a new print pattern is formed so as to overlap a previous print pattern. In the re-printing, a raising speed of the printed board at a final stage of the board raising operation is rendered lower than in the previous screen printing so that the printed board is brought into contact with the underside of the screen mask more slowly.
