If you failed math like I did. A 0.005 inch stencil would work fine for those parts. Most stencils are 0.004in for fine pitch 1005s 201s. 0.005in is probably the most common generic stencil. 0.006in generally is if you need extra solder for big parts

Thanks very much everyone. > > I'll try out a > 5mil and see how that goes. If you are using 6mil stencil and you are saying that you need more on the 0603 parts then you might want to look at your squeege pressure. What kind of squeege blades ar

Your uising 6 mil thick screen on 0603 and sot-23 and you think you need more paste? when i use a 6 mil screen on a sot-23 and 0603 it is almost to much paste. 5 mill does just fine on those parts but if you think you need more paste then don't go t

We're in the high rel market and use a lot of 5 mil stencils. They give plenty of paste to meet IPC class 3 and survive over 1000 cycles of -40/+125C thermal cycle testing.

A few years ago a lot of stencils were 6 mill and 7 mills and a lot of people still use them. these days with such a hi mix on the boards 5 mill seems to be a good compromise. if the 6 mills is working for you that's fine. One thing to note as you go

what's your final verified ok stencil thickness for the QFN and BGA?

Hello Greg, Here are a few questions and advises that might post an answer: 1. How thick is your current stencil and what is the part that requires that thickness? 2. Can you use a carrier to keep your board straight and avoid board warpage? May

Greg, this is a huge pitch. 0.16mm is safe for this size of part.

Thanks. It starts to make sense. There is a formula at the bottom of this page: http://www.circuitinsight.com/programs/50456.html It says: Stencil Thickness = 2.64mil + 0.0831 * pitch of component in mil. for 1.13mm, that gives exactly 0.16mm. So,
