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

if you cannot spend any money I would say that you either need to add rails or try to increase the squeegee pressure to hold down the stencil while it prints those close pads. But...... Can you put PCB onto some type of carrier that would move thes

We are big mpm fans especially the UP2000/2500 dos based. I just got an MPM SP2000 but feel thats too big. I would like something even smaller for an office setup. I looked up the MV100 and it came up with a pic of Quad. It looked pretty big in p

For height, I start +-2mil usually. For 3mil stencils, my lower limit starts at 1.5mil, upper is 5. If the area is chem ethed, I normally add .5 to the stencil height. My default volume is 60 - 160%. Then print specs are adjusted till I see fit, then
