What kind of quality improvements could be expected by implementing MPM's Rheopump instead of using squeegee blades on a stencil printer?

We will be using the same paste for all boards. We would need to change head because of board widths. Is the amount of time changing heads comparable to the time changing squeegee blades?

Hi, I was wondering what are the differences between a "trailing edge" style squeegee and a "diamond section" edge style. What applications tend to favor one over the other? Thanks. We are using a DEK 265

I have found all the advantages (that others have spoken about) are true. One thing to look at is the quick disconnect system that MPM offers which will reduce changeover times to almost the same as blades. It's well designed and so far, for us, has

Hi, Check to make sure your paste is not dried up, and it should roll across the stencil, not slide. Also, if your running in a cold environment, then that can stiffen up the paste, and it will still to the blades, and not roll over the stencil corr

We also had issues with paste sticking on our Trans Automation printer and switched to the Permalex blades. That made the biggest difference with release. They are a little pricey but it was worth it.

If you require several changeovers per shift the quick connect closed loop pump option would be your best bet.You can change between pump and blades within minutes. Hoever if you have several different size pumps a simple pump switch over would be pe

I don't have any actual "hard" data to give on improvements but, I can share some experiences with you. What we noticed when we implemented the Rheo pump was: No more solder "skips" on our boards, Improved print quality on our BGA's & 16mil fine pitc

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
