Outgassing is a good reason to wear eye protection when soldering larger diameter holes on a PCB, where there can be more solder & the space for a bigger bubble to form that expands when heated & can discharge the solder like a molten round.
Happened to me at work once, assembling terminals that I would later find in use at banks over here in VR. The crater the solder ball's impact created thankfully was in the white of my eye. 73, ex-VR2BG/p. ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
