Screen printing

A rubber, plastic or wooden squeegee is usually used for screen printing. The paste is spread over a screen with the help of a squeegee. The screen consists of a plastic or steel mesh. On the mesh there is a flat plastic layer with openings, which represent the negative form of the printed image. The product to be printed is in direct contact underneath the screen. If the paste is pulled over the screen, the paste remains in the openings on the product. The thickness of the mesh determines the thickness of the paste layer after printing.

Screen printing is used for both solder and sinter pastes.
