ABSTRACT:
A single screen printer (200) holds at least two solder stencils (225). The screen printer (200) receives a printed circuit board (105) and determines a printed circuit board configuration. When the printed circuit board (105) is of a first configuration, the printed circuit board (105) is aligned with a first stencil (225) and solder paste is selectively applied to the printed circuit board (105) through the first stencil (225). When the printed circuit board (105) is of a second configuration, the printed circuit board is aligned with a second stencil (225) through which solder paste is selectively applied to the printed circuit board (105).
