What size paste roll do you have on your stencil? It should be about 1/2" in diameter. What type of paste are you using? I have found that certain Mfgrs have this problem with some of their formulations. What typoe of printer and what is your squ

I had this problem once a loooooooong time ago with a 248 that was at my previous place of employment. If I remember correctly, my issue was caused by a set screw on the drive gear that had worked itself loose. My issue was stright forward and quickl

The only ones we've tried so far are Indium SMQ92 & AIM NC251 + one from Sinju (SP ?) that I can't remember the Part # for. They all printed fairly well. The pump seems to be a bit more forgiving than traditonal blades. The Rheo pump may mask some pa

Are you changing heads because of pastes or just changing widths ? Changing the head w/o cleaning is fairly straight forward. (Actually it's Pretty easy.) We have two widths - 8" & 12". We switch twice a day with very few problems but, we don't have

We've tried the MPM rheo., with excellent results. We saw a decrease in fine-pitch pad coverage rejects from ~20% to bacicially ~0%. Print speeds went from 1-2 in/sec (metal blade) to 4-5 in/sec (rheo.). Could probably go faster. Great throughput. Li

Good morning, Thank you for assistance. I�m not so experienced with MPM maintenance. Explain me please what is the difference between �squeegee down force� and �squeegee pressure�? Squeegee pressure is set so 5-6 Kg. How can I check squeegee down fo

Here's some quick things to look for: 1. Does your solder paste feel like concrete, does it roll-up into your squeegee blades, and stick to your stencil? If so, your problem is the solder paste. The mixture of powder and flux, or metal load is ou
