Russ makes good points. Your printer supplier can give good advice on machine setup also. We know we're printing well when: * Paste at least as big in diameter as your thumb is rolling across the stencil * Paste is filling the apertures * Squeegee

First, in direct answer to your question, DOE printer setup variables (MPM): * Squeegee speed: 0.5 to 1.0 in/sec * Pressure (metal): 1lb/in of blade * Pressure (plastic): 1.6-3 lb/in Second, supprting earlier responses, most people monitor paste hei
