With a standard valve and no-clean solder paste you may get a few good dots. But, repeatability will be terrible too many variable, air-pressure, board height (two post nozzle), valve time on/off, retract height, retract time, etc... A RMA paste wi

1.67 always on the sample boards measured. This is very fast and pretty good measurement for a paste dispense control. Boards do not stand out-side for long times. Inspect the height for critical components only, in the initial stages. Once your Cpk

Seems that if you are worried about the paste staying in the machine for too long then you are not the type of user "auto paste" was designed for..........and you will see zero benefits from it. This feature was designed to try to squeeze another f

Sr Tech We have worked on mpm since 1995 and when I worked for mpm I thought I knew the machines very well. After being self employed since 1998 we realized that we didn't know hardly any thing. I charge a very small amount for a year of tech suppo
