We run a high mix/low-medium volume smt line with MPM SPM stencil printer, MyData pick-n-place machine and a Heller reflow oven. That combination is working well for us.

Do you glue SMT parts on the bottom? If so, use your SMT glue to prevent the short. Just cut a new stencil with 0.020" wide apertures between the pads of the connector (bottom side). We do it all the time.

Depends on a few variables. Could be the part, your profile, your paste, your stencils..... many things affect it.

We are a small prototype small volume shop looking at getting more work that involves placing BGA's. What are the concerns or issues that we should be focusing on. We have an ABW 10 zone oven and a Mydata TP11-UFP with a SMT techniques stencil printe

I use loctite 3616 chipbonder for stencil printing and have good results. If using with a shot meter Loctite 3621 has also produced good results.

We use Axarel 2200 as recomended by Vitronics Soltec, which is the same as we use on our MPM printes for under stencil cleaning. It is non-ozone depleating and has a high flash point. For insurance purposes we banned IPA from the shop floor some

I'd like to hear from anyone using the PumpPrint stencils to dispense/print solder paste. Are you using ProFlow or just squeegee blades? How often do you have to clean?

Mike, I do not believe the PumpPrint stencils are use for applying paste. We used them for applying adhesive on a particular PCB that required tall dots for larger components. We use the ProFlow system exclusively for paste and adhesive application

DEK has it listed on their literature as an application for the stencil technology, although most of the discussion is for adhesive. Thanks for the feedback.

Ray, 10x16 should give you .62 area ratio, Theoretical Solder Volume=800. You should increase the width and the length to get better solder release.
