Robert, Here's my recommendation's: Solder paste opening on screen should equal the solder mask opening on board. Stencil thickness at .008" but this should not be your main concern as stencil thickness should be determined by the fine pitch that ar

Try using some of those new polyimide stencils. They are 8mils thick and can prevent shorting if it is due to solder mask problems or too much paste. http://www.solder.net/technical/tips.asp BWET

We didn't intend to light anyone's fur on fire [get anyone's underwear in a knot, roil the waters, have a cow man] about consultants. The Phil Zarrow wrote a useful paper that could help in evaluating paste. Here read it ... Evaluating Solder Paste
