Hi Chris, Mini stencils are a pain to line up and then holding it still while trying to print is almost impossible. We used to use tacky flux but found the Stencil Quik gizzmo from Best works the best. Give it a try. http://www.solder.net/stencil

Who out there uses a mini stencil to paste some paste when they replace a BGA and who uses just flux? What are the benefits or both and more importantly - how many times can you do both on the same component / board? Thanks in advance! Chrissie

Ewwww metal mini stencils? Try http://www.circuitmedic.com/products/stencils.shtml We use their flextac stencils all the time and they work perfect. You can get a couple uses out of each of them if youre careful too. Just line it up under a scope and

We have had issues with using the ones from Best. The holes are not always cut correctly and the edges (inside the holes) are not well defined because of the kapton material they use maybe. Plus you leave the mini stencil on the PCB under the BGA whi

We always apply solder paste to either the PCB pads or the BGA balls. I have found that only using liquid or tacky flux does not always ensure proper wetting of the pads. Also The BGA sits closer to the PCB making cleaning and endoscopic inspection

We make a custom mini stencil to print the paste onto the QFN and flip over to load on the rework station. The mini-stencil was designed for SRT to pick up the QFN. Check BeamOn (stencil house) for detail. Good luck

Look when it comes down to it. The Mini Micro Stencil Mini Mirror for $40.00 beats all and is the most cost effective inspection tool out there.

I've cut component patterns out of old stencils. Not as good as buying a new mini stencil but still it worked. I guess you can't buy those pre-pasted boards? I've never tried them but they look interesting.
