We have a 70 page check we use. Just need to verify the board layout can be processed thru all required processes.

Hello, I'm looking for a protocol description of the SMPI interface (we would like to connect a SMPI machine to a SMEMA machine). Does anybody have description of signals (electrically) + waveforms + pin-layout + connectortype? THanks Regards bas.r

Solder beads on small caps and res.

Electronics Forum | Wed Nov 29 14:49:38 EST 2006 | MS

Any recommendation to reduce solder beads next to 0402, 0603 and 0805 caps and res? What about home plate vs. bow tie stencil aperture design?

We've used both effectively to resolve this issue. Check with your stencil manufacturer. Often, they can give you a very good starting place on issues like this since they see everyone's designs. John S.

I have used a 10% area reduction with home plates on 6 mil stencils with good success. If you're using 5 mil stencils you might go with 0 or 5% reduction.
