Use a 0.002" to 0.003" thick stencil. Use an electroformed stencil from Photo Stencil or one of the others. Use -500 +635 paste or a -500 paste or type 5 or greater paste. I have printed at 0.008" pitch with 0.004" pads. It can be done.

We've been doing this for over 10 years using flux. We print a tacky flux first using an 0.002 or 0.003" thick stencil, then print paste using a thicker stencil with the underside half etched to keep it away from the flux. In our case, we can't jus

Where blank are the balls on a BGA supposed be? UNDERNEITH, dammit!!! Fire that inspector. It's good that you have your balls imbedded in something, so that they are not rolling around. Beyond that, consider the five ball system! - No more than
