I'm trying to find information/articles describing the effects of temp and humidity on solder paste. Just recently we have gone through a change outside temperature and humdidty and have notice solderabilty problems with smt boards.

I'd expect pot temperature to affect components and bare board performance before affecting the solder connection

Maybe increased barrel fill? Raising pot temps slightly seems to increase barrel fill at selective solder, something we battle with.

It makes sense. With temperature viscosity will change, and more liquidus material will flow better.

Evtimov: IDEALS Project was one of the first to talk about componebt and board damage caused by LF soldering temperatures. There's lots of more current stuff on the web. Here's some that may help: * Assessment of Long-term Reliability in Lead-free As

Thank you all for the feedback. DaveF, thank you for the articles.

Tuan - How about Sn/0.7Cu? It's M.P. is 227 and it's readily available. If the leads are Gold plated you might consider pre-tinning them. If you need a higher temp alloy any of the major solder companies can help - I suggets you start with Ind

Tuan: Consider Sn 96.5/Ag 3.5 or Sn10/PB88/Ag02 also. As Glenn says, you had better get rid of that gold or you will never have a shiney connection. Not that a shiney connection means anything about the quality or reliability of your soldering. M

Glenn and Paul have hit the nail right on the head. Continue working with your solder vendors. I know that many people have succeeded with what you are trying. And the Pb-Free push is only making things better for you as companies develop just wha
