Abstract
A brushing system to be used in the manufacturing of electronic modules for removing unwanted particles from the substrate surface before the final encapsulation of the modules. The system provides an epicycloidal movement of the brush bristles on the substrate, which results in very effective in the removal of the particles. The system comprises a rotatable shaft with an eccentric bore. The hub of a rotatable brush can freely move inside the bore. When the shaft is rotated by a motor and the brush bristles are subject to friction, the brush describes an epicycloidal movement.
