Abstract
A printing system including a squeegee and a blade assembly. The system further includes moving paste retainers and at least one cross elements. The cross elements include one or more cross wires to affect a wiping action of the blade during a printing cycle of the squeegee. The motion of the paste retainers and cross elements created by pivoting paste retainers. The wire motion is set on an arc at a fixed radius from a pivot point, and arc traversing a significant part of a front face of the squeegee inside of solder paste or viscous material mass. The cross elements include multiple cross wires or thin blades to affect more shearing action with less motion.
