Kester 24-9574-7610 K100LD Lead-Free No Clean Wire Solder.020" Diameter-Low Cost Alloy

Despite all the hype about silver bearing solder even though the silver content is very low, silver bearing solder does not leave a glossy finish even when done correctly but rather a satin finish. Silver bearing solder also shrinks besides looking like a cold joint with lead solder. Kester did their homework with this one. As a diyer I can easily use lead bearing solder, but I want to get used to using lead free as I suspect at some point there will be pressure to take lead bearing solder off the market. To be Rohs compliant commercially you cannot use any lead.

This is the best lead-free solder I've ever used. None of the flow problems or peaks that SAC305 and similar alloys sometimes have.

Bought this after reading countless forums saying Kester solder was the best of the best. To be honest, not sure what all the hype is about. It worked fine, but nothing above and beyond the many other brands I have tried so far.This particular solder smokes a lot and I ended up having to heat much higher to get a good flow with my weller soldering iron. The splatter levels were relatively low, which is nice. Definitely have to setup my fume extractor whenever I use this solder.

Works great with enough heat. I'm no pro solderer, but use this on a few SMT parts and it works well.
