I thought there was a link for test labs somewhere on the site, but didn't see it in a quick look. Here are some I know of that should be able to run the test: Trace labs ACI Technologies (American Competitive Institute) STI Electronics

We have problems with solder balls after reflow. Anybody have any ideas as to what causes them?

Search the fine SMTnet Archives to get started, until the Solder Ball Troops arrive.

We have successfully put .016" vias in .030" pads. There is no issue with .030" solder balls, since the actual volume of the .002" via in pad is small compared to the ball+solder paste volume. We did notice random bubbles where, apparently, the sol

If the solder balls are next to your discretes, you should consider a homeplate design on you stencil apertures. THe only other time we have seen soler balls is due to the raw card. If the vias are not plugged by the solder mask, solder and air can g

Mask finish is the #1 variable for micro-balling with wave and selective processes. The #2 variable is the Flux. There are some flux formulations out there who're known to have additives that virtually eliminate micro-balling. However, keep in min
