Kester 24-6337-0010 44 Rosin Core Solder 63/37 .020 1 lb. Spool

This is some of the best solder Ive ever used (and Ive used a lot). Great action from the flux, resulting in nice flow and soldering. More expensive than other brands, but definitely worth it.

This review is not of the Kester solder, but the seller, Kimco Distributors. I ordered a 1 lb roll of Kester 44, and when it came the spool was covered in sloppy packing tape, and the actual solder spool had a birds nest. I take that term from bass fishing - its meant to describe the mess you get when you use a baitcasting reel (which has a spinning spool) and dont stop the rotation before your lure hits the water. As I pulled solder off this spool, it was coming out from underneath many layers of solder which was deeper into the roll, but physically on top. So I kept getting kinks. I managed to cut a bunch of it away (had to throw away solder) and got down to the deeper part of the spool, where it was coiled tightly, but now still, the solder is coming out from inside of the spool. Its possible that this was screwed up at the Kester factory, but I doubt it. Is this seller re-spooling their solder, and doing a sloppy job at it? It makes me question whether Ive really got genuine Kester 44 at all, in fact.

perfect size for quad building..wish they hadnt placed the inventory label across the end of the spool on top of the solder label which tore off while unpacking...now the ID label for this spool is gone

Works as expected and gives a clean contact on the circuit board

top notch

Good size for fine through-hole work. Flux gives perfect wetting and doesnt smell terrible.

I do not have a ton of soldering experience, or experience with different types/brands of solder, but this was exactly what is was looking for to do component work on circuit boards for some side projects of mine. The diameter and solder mix work excellently and there is definitely a reason that Kester solder is so highly sought after. A big supply that will last a long time and is certainly worth the cost!

Excellent solder! I was really surprised at the heft of this roll. Great for re-flow, and drag soldering.

Qualit easy flowing solder. Kester rules.

better off buying another brand
