The mini-BGA was to be smaller than the standard BGA and larger than the micro-BGA. The last I heard there will be no mini BGA but companies such as Tessera, AMKOR-ANAM, etc. will go directly to supply 0.020" center to center pitch micro-BGA's. You

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

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

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

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

It really depends on pad design and other component on the PCB. Most of the time I run 0201s I have microBGAs on the board and usually print 3mil. Reduction will depend on the paste. For leaded paste you will have reduction (about 10% or so).For Lea
