After a recent scare with our 30 month old having elevated lead levels after a test I’ve switched to Pb-free, both solder and solder paste.
Currently I’m using Kester NXG1 paste but I wasnt satisfied with how it flowed once heated nor how it dispensed so I got it all out of the syringe and mixed it about 10:1 (just a guess, not measured) with kester liquid no-clean flux and shoved it back down in the syringe (a hell of a job) and now I’m pretty happy with it, tho there was a new learning curve where I was having some fit’s with it. Its surprisingly easy to get it to stick to pin’s, getting it to adhere to the pad’s is a little more of a job than lead solder. If I was using bottom heat it would probably be the other way around (I’m using hot air).
