I'm doing lead-free SMT of BGA with 450 micron ball. I found there are lots of voids under xray, there are around 2-3 voids in every balls. It is around 10% of volume ratio. I would like to ask if anyone know there is any standard of acceptable maxim

NO-LEAD COMPONENTS WITH LEAD SOLDER ISSUE: We agree with Russ. We've dicussed this several times on SMTnet. For instance, look here http://www.smtnet.com/forums/Index.cfm?CFApp=1&Message_ID=25394 LEAD COMPONENTS WITH NO-LEAD SOLDER ISSUE: We disa

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
