To all, I did a little more digging and found the following. Here is the site for NASA-STD-8739.3 http://www.hq.nasa.gov/office/codeq/sldrbch1.pdf on pages 39 and 40 they talk about high voltage soldering for turret terminals. This information could also be applied to circuit boards.

I am looking for information pertaining to Ball Soldering for high voltage PCB assembly. Is there a IPC standard or a procedure on how to do this technique?
