Does pot temperature affects quality of the solder joints?

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

Hello davide, the biggest advantage you'll find with a complete N2 tunnel is the minimization of oxidation during board preheating. Using only an inerted solder pot allows the oxidation to build up throughout the preheat stages and introduces contami

I want to know the advantage of using complete inert soldering wave machine (with Nitrogen, Tunnel concept) in comparison to use just a soldering machine withe inerted solder pot. Thanks

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

easier if you recycled on-site? You can still send off for reclaimation the oxide powder that your left at the end of the process. Failing that talk to your supplier to see if they have arrangements to do this for you or look at reducing dross - i f

On an ACE KISS machine we could program a drop in Z height to give a peel off angle after the component was soldered. Usually not necessary as the solder at the nozzle is falling away from the lead down the nozzle. If possible, we would program a fr

We have a Vitronics mySelective machine (model 6749, or "the Fat Bastard" as we affectionately call it). It's configurable with various combinations of "select wave" and "multi wave" pots. Ours has one of each. The "select wave" is for the most pa

Check flux penetration and type of flux. How much is solid contents. The solder filling is better under Nitrogen. Check the time (speed) of the nozzle whether is correct. Usually For SAC305 the temperature of bath is 320C/degrees, but only for sel

Looks like a time/temperature problem to me. However, there are a lot of solder fines surrounding the pads in one photo that go beyond what I'd expect from inadequate TAL. Is it possible that the board was misprinted and not completely cleaned, or

lead free and tombstoning

Electronics Forum | Fri Feb 17 11:01:47 EST 2006 | amol_kane

with lead-free solders, one would expect to find less instances of tombstoning. this is because SAC alloys are not eutectic and melt over a range of temp (usually 217-220 deg C) instead of at a single temperature. therefore the forces due to solder s
