Kester 24-6337-8800 50 Activated Rosin Cored Wire Solder Roll, 245 No-Clean, 63/37 Alloy, 0.031 Diameter

I know its not politically correct to say this but wow - what a relief to get back to a good tin-lead solder vs. the no-Pb stuff I struggled with. Just could not make it work with my controlled temp Weller station. I love this Kester alloy.

Excellent solder. In my opinion, it’s better than the tried and true standard rosin. The activated rosin is a stronger flux, which allows to use a lot less in the core than standard rosin. So not only it works slightly better, but it leaves much less of a mess than standard rosin behind. You can hardly notice it. Truly no clean needed.

With regular 60/40 solder, the solder undergoes a plastic period where its not entirely a liquid and not entirely a hard solid. If you bump or wiggle the joint in this plastic period, it ruins the joint. Save yourself the hassle by just getting this formulation which more or less eliminates the issue. Bump to your hearts content.

This solder is great. The rosen core really helps. It flows smoothly and clean. Highly recommended.

I made the mistake of purchasing 2 because of past experiences with other brands. Usually when you buy these reels, they pad the spool halfway so you think youre getting a full roll of solder when half the roll is plastic filling. Not in this case... you get a full FULL FULLLLLLL roll of solder that lasts longer than most marriages. Im barely halfway through my first roll. Definitely recommended.

Good product. Good service.

This is the best stuff you can get and for a fraction of the price.

Best solder I’ve found when working with simple circuit board applications. Doesn’t smell horrible and is very easy to flow without a lot of gross flux. Have been using this for years. Worth it.

I prefer Kester solder and have always achieved good results using Kester Solder. This size is my go to for general solder tasks and a one pound spool last a long time.

Awesome stuff
