I hope you are not trying to melt the Ceramic BGA columns. these are not meant to melt. I would run a lead process at peak temp of 225 -230C with lead paste. The board warpage may be of design issue or Manufacture issue. Russ

Does anyone have a recommendation on a user- CAD-friendly, cost effective, software for production personnel to use to pull up component information (ie part no, silk designator, shape, feeder no, etc). Thanks...

We have one of the triples, it advances much more smoothly than the Siemens feeder and is easier to load. It is a well designed feeder, the drive mechanism uses some kind of plastic gears - but we haven't had it long enough to know if how well they w

Check with sigmaprint. They are the origional designer and have an upgrade package. The reason that piece is so expensive is it is a one piece machined stainless steel foil that is 0.010 inch thick. http://www.sigmaprint.co.uk/spares.htm

The ideal and most cost effective solution to this problem is to purchase the FineFoil/CustomFoil retrofit kit that we have designed and can supply. http://www.sigmaprint.co.uk/customfoil.htm

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.

orientation is also a factor here, So what is the pitch of these connectors? the lead length? the hole dimensions? surface finish? and what type of wave and flux are you running? Shorts are pretty easy to eliminate if everything is of adequate des

We discussed about applying 2 dots of glue on either sides of the LED body, but have yet to try it out. Other discussions include conductive adhesive, using fixturing with weight, different stencil aperature design, hand soldering.

The best practice is to perform a design of experiments. Without knowing your product or board composition, it is sensless to recommend any flux or solder. Contact some local area wave solder sales people. There are also "no lead specialist" that
