Stencil Printing for MPM model # SPM| 16 March, 2001
Anyone out there have a real good stencil printing process control document for an MPM Corporation stencil printer model # SPM? We are seeing lots of bridging, wetting, and filling problems. Thanks in advance for your help.

First thing to check is that you have a good gasket between the PCB and the stencil (if not check that the tactile is free of paste at the base of it and calibrate the tactile. I am assuming it is not a head mounted tactile) Also check that the wiper paper is funtioning correctly and that the solvent is dispersing correctly, is the wiper plenum set up correctly to the correct pressure (25psi for a AP27 & 45psi for a Hi-E).
