Kris, this practice has gone on for years. I have never heard of any problems associated with this. I have heard "grumblings" about tin lead parts being processed with lead free paste, but have seen or heard of no data to support. Russ

I have experienced this directly in SMT and wave solder. Fillet lift (can) be a direct indicator to lead enrichment (but its not the exclusive symptom). Lead enrichment in smt joints reduces the interfacial strength shortening the time to creep f

To take our turn at keeping everyone else on the straight and narrow. For more on lead contamination of no-lead solder, look here: http://www.aimsolder.com/techarticles/Lead%20Contamination%20in%20Lead-Free%20Electronics%20Assembly.pdf [We apolog

Now see Dave, now I have some good info on why it is "bad", This must be the lead enrichment I have heard about but never got any substantiated data or explanantion. I wonder how much weaker or less reliable these are. Is there any data that you k

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

We use both in our selective soldering machine. Training is the most important concern. As long as you have well trained operators the risk is minimized.

Thanks for replying... Unfortunately (or not) it isn't relevant anymore. Due to the effects of covid-19 we don't have any active aerospace customers anymore so (for now) we're only making leadfree products.

Yep, done it previously with a multipot machine. Using with wirefeed to top up the pots means you only have a contamintion risk when you fit a new top up reel. Used separate nozzles for both, but theoretically using titanium nozzles would mean no c

I have done it different ways on different equipment. 1. Remove alloy one from the machine. Add alloy two only. and use it.For next board, do the same. 2. There are machines with separate sections for PB and PC-Free, so pots are away from each other
