Abstract: A foil screen is held in registration with a printed circuit board during the application of solder paste on the printed circuit board, within a frame assembly with a prescribed tension by providing a rigid frame for juxtaposition with the foil screen, engaging the foil screen with at least one coupler, engaging the one coupler with a tensioner for resiliently biasing the one coupler to exert a tensioning force of prescribed magnitude upon the foil screen to tension the foil screen with the prescribed tension, and selectively applying an actuating force to the one coupler, the actuating force being opposite to the tensioning force, and selectively releasing the actuating force from the one coupler, such that upon actuation of the actuator to apply the actuating force, the tensioning force is overcome for release of the foil screen from the one coupler, and upon actuation of the actuator to release the actuating force, the one tensioner resiliently biases the one coupler to exert the tensioning force of prescr
