| | I am not familiar with the "mil" metric. How many inches is in 1 mil? | | | | ...or 10 mil? | | | | | 1 mil= .001 inches | 10 mil= .010 inches | Also, it has nothing to do with metric. I was also confused with this standard of measuring bef

I have done this before, We print with a 5-6mil stencil and have had no problems with any underneath solder. If you are still nervous instead of removing from stencil use some 3 mil kapton tape or equivelant and tape off the BGA pads. This way the

I think you have your pitch wrong but anyway, I have never had success with wave soldering anything less than 50 mil pitch. On a QFP I have had good luck on three sides of 25 mil but never all four sides and without defects. Mask 'em off and hand s

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

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

Thanks for the clarification! So in generic settings what are the normally the components with the smallest pitch? Will a machine with 20 mil capability handle almost anything? | | I was wondering what measurements are used to define pitch? | | |
