The keys to avoiding the voids we have found are: 1. Proper reflow profile 2. Proper stencil design 3. Prebumping using either a metal stencil or StencilMate stencils (and then using paste flux to attach later) http://www.solder.net/products/stencilm

20X magnification, using 0.5 mil accuracy, is helpful. I have a MicroVU system for geometric measurements in my Receiving Inspection, which is used to also measure the new stencils to ensure aperture reductions requested are actually provided by the
