NASA is concerned about outgassing in high-vacuum environments. They select materials to minimize outgassing. http://outgassing.nasa.gov/og_desc.html

Both "moisture content of bare board" and the "thickness of the copper plating in the PTH" are related to each other. As you heat the solder connection, moisture in the board boils and out-gasses through the solder connection. Plating with the proper

One of the common causes of solder ballin is also outgassing from the boards have your tested the board for outgassing? Bob Willis

Thanks Russ. I have contacted the board house. Will post results later.

The root cause is dependant on the type of solder "splash", ball, whatever, that you are seeing post reflow. If it is smears, then cleaning the stencil underside is probably the answer. Are you using automatic wipers? How many print cycles between w

Large voids are common in via in pad [seach the fine SMTnet Archives for earlier laments], especially in blind via. Observations on your via out gassing theory: * If the copper plating on your via is GT 1 thou, there will be no outgassing from the

Are there via's underneath the Tantalum, closed with soldermask on the other boardside only ? I've had a situation recently where a chip resistor was blown away by the outgassing of via's under a Tantalum. The presence of the Tantalum caused the vap
