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

No matter in selective soldering or wave soldering process, higher pot temperature and longer wetting time can increase IMC thickness and joint strength(reliability), but as Daivf said, you need to care if the DIP component and bare PCB was damaged b

I was actually thinking about the wave soldering machine.

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

Selective Soldering Frames can pull large amounts of heat from the solder wave at the point of contact, effectively lowering the temperature of the solder at the solder joint. You should confirm the temperature of the solder joints by running a therm

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

Is this for a Selective Solder? If so what size nozzle do you run. I run at 315 C most of the time. You can speed up your process time and still achieve good solder fill.

Dave, what do you mean affect the board? Any literature on the subject here in the forum or any at all?

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

I think OA flux left on the pot would quickly looses its activity and become part of the dross waste stream, and smoke stream for that matter. Also, if your wave is setup properly your selective pallets will scour (push) the top of the lambda wav
