The squeegee pressure is the force with which a squeegee is pressed onto the stencil. The squeegee angle is formed from the squeegee force via the spring constant of the squeegee plate. If the force is too great, there is a risk that a flat angle will press solder paste under the stencil, which can lead to smearing and bridging. Too little squeegee force can cause the squeegee to float on the solder paste during printing. As a result, the solder paste is not completely removed from the stencil surface. The printed paste deposits are then too high.

The squeegee force is set according to the length of the squeegee. The following applies for steel squeegees 2 ... 3 N/cm squeegee length.
