Kester 24-6337-0027 Solder Roll, Core Size 66, 63/37 Alloy, 0.031 Diameter

Was dubious of the 63/37 alloy (having grown up on 60/40) and the thin wire until using it. Flowed well and the thin wire required less heat. This is my new go to.

Great product.

Excellent solder

well described. its an excellent product and suites my soldering needs. produces clean and shiny solder joints as expected. i would buy another one if i run out of it.

This solders strong point is also its weak point in my opinion. Ive been soldering daily for a long time and have used various kinds of solder (lead free at work). I typically use leaded solder at home. This was my first roll of kester. I have to say, it solders wonderfully, though no better than other quality leaded solders i have used. The thing is, clean up of the flux is a nightmare. It turns into a hardened gooey mess and cleaning takes 3-4 sessions of scrubbing and blowing off before things are cleaned up. I would call it abnormally difficult to get clean, in fact. Now you could say, its no clean, leave it alone.... Each to their own, but thats just half-assed imo :). The job is done when it looks stock and its clean.

The original great eutectic 63/37 solder from one of the best makers on the planet. How can you beat that?

Great to do electrical work with. It heats rapidly, flows smoothly, and makes a perfect joint. I would highly recommend it to anyone interested in buying such a product.

Best solder ever. Really no need to buy anything else. Been soldering mostly vintage electronics and guitars. Have used various brands, from Chinese well-reviewed soldertin to suggestions from local electronics store, but nothing came even close to this quality. Always a perfect shiny joint and dries immediately without plastic phase, so well worth the extra cost over the 60/40 version

Always used this in electronics and circuit boards. Excellent !

Ive been using this solder for over thirty years. Industry standard. Wouldnt change for the world. In my eyes its simply the best solder for electronics.
