SCREEN PRINTING SYSTEM AND SCREEN PRINTING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a screen printing system and a screen printing method handling a board having a protection film formed in a range out of an opening specified to an electrode capable of ensuring satisfactory accuracy of printing positioning.SOLUTION: The screen printing handles an individual board 5 having a resist film 6 as a protection film formed in a range out of an opening 8 specified to an electrode 7. The position of the opening 8 is recognized in an optical manner to obtain a positional displacement amount between a proper position of the electrode 7 and an actual position of the opening 8 as opening positional data. In a positioning process between the individual board 5 and a screen mask 23 which is executed prior to the screen printing, the positioning is executed based on the opening positional data. With this, printing failure caused from displacement of the opening 8 is eliminated and satisfactory accuracy of the printing positioning is ensured.
