How thick is your stencil? We print 16mil every day with type 3 paste 2 of which you have tried (Alpha and Kester) Stencil should be 5 mil. Russ

20X magnification, using 0.5 mil accuracy, is helpful. I have a MicroVU system for geometric measurements in my Receiving Inspection, which is used to also measure the new stencils to ensure aperture reductions requested are actually provided by the

Hi all, Any stencil opening recommendation for 20mils pitch mirco BGA. Currently, using 12mils round opening, 5 mils thickness. Seen to have weak joints as it crack after Ict testing. thks

I run 0201 on a 5 mils stencil with openting of 15X12 and did not have any issue. The major concern is the placement and CP643 did very good job. Type 3 solder pastes was used. Good luck.
