Hi, Please help on this problem with an MPM AP25 screen printer. Everytime we print the error Squeegee Pressure Not Set is prompted. Although we can still print by clicking on Next, it beats the purpose of having an automatic printing machine. Can s

Following a pressure error, if continue is pressed, the next print with THE CORRESPONDING squeegee should attempt to compensate by increase or decrease in pressure (as appropriate)... Is it: 1)Not changing at all? 2)Over compensating? 3)Under compens

| Tony | | Although I agree in principle with Dean that 45 Degrees would be ideal, most of the squeegees I have worked with have been 60 Degrees to the stencil surface. This seems to work best with metal squeegees when printing HASL boards, because

| looking for help with fine-pitch printing for what would be the best settings for printing speed, squeegee pressure, seperation speed. | thanks for you time Print speed is determined by your aperture dimensions, paste viscosity type of blade (metal

We've evaluated the Rheopump. Problems we've found are 1) cycle time differences between forward and backward print (evidently the pump charges pressure on one and not the other), 2) excessive amounts of paste left in the tubes (roughly 60 grams we

Thanks for your inputs. The board construction seams to be balanced and boards comes back to flat after top side process. we'll be performing experiement variing the profile parameters. if that does not do it, any printing suggestings? Would more sq

I'm trying to get an '07 Accuflex into production and I seem to have a small problem. When trying to calibrate the zero pressure point on the squeegees I drive them down until they are touching the stencil and once they touch the stencil they run ou
