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

I was previously using some pretty cheap-o solder and had such a tough time figuring out why my projects kept failing that I decided to give this well-lauded Kester brand a try. The difference was really night and day! The Kester solder flows amazingly well, and Ive had to do no rework due to mysteriously failing connections like with my old solder. Dont cheap out, buy this stuff.

I regret learning to solder with other sub-par leaded solders. This size (20AWG) has worked well for me for small electronics pads (e.g. flight controllers) and associated higher-gauge wiring, as well as more substantial pads (e.g. electronic speed controllers) with wire gauges occasionally dipping to 8AWG without any issue. When using the right flux, and only when needed, you cant go wrong with this solder unless you need a lead-free variant.

I do a lot of soldering repairing pinball and arcade machines. Usually, run through a couple of these spools a year. This is the best there is, been my go to for nearly 5 years now.

I had never used 63/37 solder before. I always bought normal brand 60/40 rolls. This solder takes me to a whole new level. It melts at a lower temperature. It is very thin and thus more suited to the precise joining jobs that new electronics require. I had to practice before I could reliably control this thin stuff, but my effort was rewarded. It is more expensive than the normal solder, but worth it to me.

Very good solder. More involved process to remove solder from iron with brass shaving method. Much better than China brands without a doubt. You get what you pay for with this product. I highly recommend this product.

Very good solder for the money

This is a good choice for your basic home electronics soldering work unless you need to be RoHS compliant. The eutectic tin/lead ratio is the easiest to use.

After spending the last year soldering tiny whoops, headphone cables, TRRRS connectors, MIN XLRs, etc... and often times getting frustrated with not getting good results, I upgraded my iron to a Hakko FX888D-23BY and while I did get good results with the leaded solder I was using, I still struggled with getting good flow and not having to turn my iron up. Bought a roll of this of many folks recommendations, and problem solved! I was able to turn my iron down, solder those pesky 4 pole and 5 pole headphone jacks, tine whoops, etc. with ease and the joints look amazing and are strong. This solder is the real deal and reminds me why I fell in love with the hobby as a kid.

Use it daily, works great! An excellent choice!

Ive been buying solder from Home Depot for years. Always worked great, never had a problem. Then, it started not to work as it should. No matter how much I cleaned the tips. I couldnt tin them. It just bubbled on the tip and didnt coat. Even on new tips. Did the same to the wires. Looked for months for a better solder. Found kester among others. Felted out of the group I was looking at that kester would be the one. Order this bundle and was surprise that it was a pound and the price was cheap compare to the amount I was getting from Home Depot. Its also thinner as well. Like the solder that came with the solder gun. Took my solder and gun. Heat the gun up and try to tin it. And it took! Next, took wires and tested it. Went on good and clean and it holds excellent. Havent had a problem with a solder joint yet. I dont expect to. I dont think it take a lot of heat to melt it. I keep my gun on a low range, but I believe even set there it is a bit too hot. Need to take a temp reading of it to find out. You really dont have to clean the solder after and no need of using Flux (unless you want too). If youre looking for a replacement. I recommend trying this one!
