So, what is the pitch of the part and the pad size, also tell us the thickness of stencil. Russ

I'm having trouble printing leads on a fine pitch part. The lead is only .008". I'm using a DEK 265 with metal squeegee and using WS200 multicore solder paste.The stencil is laser cut and polished. I've experimented with different pressures and diffe

Go 5 or 6 mil thick with stencil, i am not familiar with that pitch but I would recoomnd a 5mil. Was the thickness in this post before and i missed it? Russ

Hi dwelch123, 8 mils seems a bit thick to me. I would normally go 6 or 5 mil for fine pitch such as this. One other area to check is the the snap off. Are you using the slow snap off or just lowering the board right after print? If so you should

Russ asks good questions and I think Chunks pretty much nailed it. Aspect ratio (aperture width/stencil thickness) s/b 1.2 minimum (I like 1.5 if I can get it). If your aperture width = lead width (.008"), yours is 1. Tough to get consistent paste r

Has anyone had success using a DEK Proflow printhead with fine pitch components (~.2mm pitch). I have been told that squeegees are the way to go for fine pitch. What other major factors play a role in successfully printing fine pitch. Print speed,

Yes, I agree with Evtimov. It's more about aperature reduction and type than it is the type of machine. Aspect and and Area Ratio are very important. Take a look at this page I found on the internet http://www.qualiecocircuits.co.nz/stencil-techno
