Hi everybody, I found a defect varistor 0603 Tombstone and poor welting when we use component that terminal is Silver palladium (Ag/ Pd) with Leaded solder paste (63/37). Then we change alternative component that terminal is Ni/ Sn the result not fou

I've done some pretty scary cross-sections of chip sized coils with AgPd terminations with Pb free solder. The AgPd went into solution and there was essentially nothing left to solder to. We also had convex fillet shapes that clearly didn't meet wo

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
