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

We are very concerned about outgassing in wavesoldering. If anyone knows how to use properly well pcb's before soldering in order to avoid this problem please let me know. I have this problem in FR4 large double sided pcb's. My soldering line is

Solder Ball and Splash after Hand Soldering

Electronics Forum | Sat Jul 25 08:47:25 EDT 2009 | davef

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

Wave Solder - solder bubbles/outgassing??

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 with Via in Pad

Electronics Forum | Mon Apr 12 22:22:01 EDT 2004 | davef

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

Are you talking about small 'volcanos' that burst through PTH solder connections? If so, you have moisture outgassing through the PTH barrels: * Plating on the hole of your bare board is too thin. It should be greater than 1 thou [25um]. * Your bak
