The biggest fear is mixing the solder pastes and bar solder. Had a training program for teaching folks what the alloys are and how to read them. I have locked up the bar solder and use the buddy system to restock the pot. Put up many signs on le

Bob, Great theory if you're selling SN100C, but I have to disagree that an alloy being 4�C off eutectic will cause cracks. When a solder joint exits the solder wave, there is an immediate drop in temperature of 100�C. so being off 4�C is irrelevant.

Does anyone have any ideas on how to keep my soldering tips from turning black when using lead free solder. I am going through a lot of tips. Thanks

Hi, Is it necessary to have a tunnel nitrogen? Is it a very common practise amongst contract manufacturers ?

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

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

Hello Kris, No, it's not necessary to have a nitrogen tunnel setup. A nitrogen tunnel allows a process to go the extra step in providing higher quality through less defects. I can't really speculate on it's use in contract manufacturers mainly becaus
