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

This solder is amazing. It really is the best that I have ever used! No more having to use flux on nearly every joint, this stuff flows so well. My only regret is not having been aware of this brand when I started soldering. This is the solder that Ill use 100% of the time now.

This solder Kester 24-6337-8800 is supposed to be some of the best out there. Ive been trying to use it off and on now for 3 weeks and still cant get it to flow well. I dont know if its the no-clean flux... or if that flux is only 1%, but seemingly no matter what temp I set it at, it doesnt want to play nice. It is shiny and clean looking when it is finished, but it just takes a lot of effort to get there. Im sure there is a trick to getting it to work quick and easy, I just havent found it yet. Perhaps when I do Ill adjust this review and toss another star on so that I can let yall know how I fixed what I was doing wrong with it. Till then, Im using KESTER SOLDER 24-6040-0027 which Ive found works beautifully and doesnt take much clean up with the flux.

If you are doing electric soldering you should be using this wire.

What can I say? It’s Kester Solder. The Solder Industry Standard. It flows on like butter, hardens like shiny steel. Simply works. I use it mainly for soldering my Drones & Arduino as well as Rasberry P.I. projects. Kester solder simply performs as long as you’re using the proper percentage and type as recommended for your particular need. I will never again use lead free solder. Using Kester assures top quality possible every single time where any mistakes made are not due to this solder but the solderer be it the wrong temp, iron or technique used, etc.. I find it melts and flows perfectly for me especially on the numerous boards and wires contained in a drone at 390F to 420F but that’s a personal preference coming from someone who’s been soldering RC and drone projects over 15 years always coming back to Kester every time I’ve bought others at a cheaper or even sometimes more expensive price but what can I say? It’s Kester. Just buy it you won’t regret it.

Have nothing to say cause I have used it before at my work place.

This is worth the bucks if you do any amount of soldering. It is my standard go to.

Awesome stuff

The only solder I ever use on my drones. Nice, shiny solder joints every time!

Great solder. Got some perfect shiny joints.

I purchased this soldering wire on the recommendation of many an RC enthusiast. I initially had some difficulty making this solder “stick” to PCB pads (@350C), but after cleaning and recoating my soldering tip, thereby removing my old soldering alloy and replacing it with the new, it was smooth sailing. The solder flows easily and sets quickly once the tip is removed. It also results in a lot less flux residue than what I am use to. Minimal cleanup, if any. Highly recommended. Thank you for shipping to South Africa for me. Could not find Kester at all, locally.
