You can go with smaller chip parts (0805 to 0603 or smaller). What size is D1? Can you go to a smaller package. Provide more details. You may not have the real estate to include the silksreen (i.e. reference designators). Consider omitting them.

The quad 1000 is best used for 0805 parts and larger. It is termed a chip shooter meaning 'for the most part' passives only. There is no optical alignment and it has mechanical centering using precisor pads. Fiducial finding is done with a beam and n

"I believe I was the one who stated in an old post that prying the leads is rediculous." I have been down this road as well. The prez of my previous employer decided that because he could pry .012" leads off the pads with a screwdriver that we had a

We are a small company, reletivly new to doing our own SMT (1 year) and we are having an issue, I think. We manufacture many board with no problems, but we have one that constently defeats us. This particular PCB has ENIG finish, and we have had th

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?

Billy and Chris have a good point, pad size and geometry will affect proper aperture size and geometry and could result in tombstoning. Also I have seen chips which require special pastes but I have never found this to be the cause of tombstoning, in

Dave, to answer your questions, point-by-point: � Just out of curiosity, how are second side, skippy components oriented on the board with respect to the wave? The SMD's are all oriented in the "correct" direction with respect to wave direction(i

99% good solder joints = 10000 ppm (defects per million opportunities). Having only built with 0603s I can't speak for a target but that still seems pretty harsh....with a 75/25 0805/0603 ratio at my last place of employment I think we were running
