Abstract:
1. A stencil printer for printing viscous material on a substrate, the stencil printer comprising: a frame; a stencil coupled to the frame; a substrate support coupled to the frame to support a substrate in a print position; a print head, coupled to the frame, to deposit and print viscous material over the stencil, the print head comprising a controller coupled to at least the print head, the controller being configured to control the operation of the stencil printer, the controller further being configured to (a) determine a calibrated position for each of the first and second force values and (b) calculate and apply a desired print force based upon the calibrated positions of first and second force values and actual positions of the first and second force values as detected by the device with the at least one squeegee blade in place.
