Who is using two sorts of tin in one selective soldering machine with to solder pots? So then the soldering program selects the correct pot (tin). What are the risks? Adding wrong tin in the wrong pot. Mixing up the nozzles?

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

Grant, Why don't you try a water-base flux which is No-clean, VOC-free also? I have tried the 270WR flux from AIM with good results even on lead-free process. My $0.02, George

We're soon to build a lead free assembly with 0201 components. I'm not worried about placement as our machines can handle it. Any tips on printing, screens, reflow?

Where to find detailed information on fluxes? No one seems to know the real difference between Rosin fluxes with colophan, Resin fluxes or synthetic Resin fluxes, No Clean, Low Residues, VOC-Free, Halide-Free, Water Washable with alcohol base, Resin-
