Abstract
PURPOSE:To equalize the printing widths of sides perpendicular to the moving direction of a squeegee and sides parallel to the moving direction of the squeegee, of a creamy solder printed, by setting the width of a sides of a screen stencil pattern perpendicular to the moving direction of the squeegee to be smaller than the width of the sides of the screen stencil pattern parallel to the moving direction. CONSTITUTION:Of four sides of a screen stencil pattern 4A having a rectangular frame shape, the sides 4a perpendicular to the moving direction (a) of a squeegee on a screen printing press have a width W1 smaller than the width W2 of the sides 4b parallel to the moving direction. When a creamy solder is printed on a printed circuit board by use of a printing plate having the screen stencil pattern 4A, the creamy solder is printed in a rectangular frame shape corresponding to the pattern 4A. In this case, there is a tendency that the amount of the solder applied is greater at the sides 4a perpendicular to the moving direction of the squeegee than at the sides 4b parallel to the moving direction. Therefore, with the width of the perpendicular sides 4a initially set to be smaller than the width of the parallel sides 4b, the printing widths of the perpendicular sides and the parallel sides of the creamy solder are equalized.
