ABSTRACT:
A screen printing machine comprising a backing plate with holes conforming to components attached to the surface of a flexible circuit board. The machine includes a screen which patterns solder paste on the surface of the circuit board while the circuit board is on the backing plate. Also included is a spring loaded element disposed adjacent to the backing plate which applies a predetermined continuous force to the four corners of the circuit board. This force is applied in a diagonal direction to the corners to stretch the circuit board so that the circuit board is parallel to the backing plate during screening.
