KESTER SOLDER 24-6337-0027 Solder Wire, 63/37 SN/PB, 183°C, 1LB

Its solder. It melts when its hot, it solidifies when its cold.. nuff said.

Rosin isnt listed anywhere in the description, but it is on many of their products. This product has rosin and shouldnt be compared to solid core.

I’ll be buying again

Im a fan of this stuff. It flows beautifully, way better than the generic solder I previously had.

Excellent solder. Using it for board repair on macbooks.

A high quality solder that flows easily. Kester is used where I work (electrical engineering R&D lab). I’ve got a good deal of experience working with it and it’s great stuff. If you’re a hobbyist looking to buy in this quantity, make sure it’s something you know you’ll be happy with. I feel safe in recommending this solder to anyone, but we all have our preferences and nothing beats first-hand experience. Since I expect this roll to last me at least 20 years based on my usage rate, this is well worth the extra $0.50-ish per year I could’ve saved by buying cheaper solder from an unknown manufacturer.

I suck at soldering. My hands are really shaky and I dont do it often enough to get the practice. I cant believe how much of a difference this made over the cheap stuff (which have thousands of 5 star reviews!) Id been using. It flows where I want it to go, very easy to use, low temp.. For years Ive been thinking about trying this, but the price compared to others is significant. I had tried a little tube of it awhile back and didnt like it at all. I didnt know I had brought the wrong type (the naming of various solders is a bit confusing) I finally broke down a few months ago and bought this. I was getting so frustrated soldering I started buying in stead of making. It is absolutely worth the price. Its not a miracle tho - I still suck at soldering, I just suck less now.

63% lead and 37% tin is generally used considered perfect for electronics hand soldering. Kester 44 rosin core flux is generally considered one of — if not the — best for electronics hand soldering. And 0.031” is just about the best diameter for small chassis, through-hole electronics, and SMT down to about 0805 and even 0402. As a result, this is a great solder for most electronics hand soldering. This is a great solder.

Solder is too important to try to save money on the cheap stuff. This roll will last me at least 10 years, so why shouldnt I pay a little extra for solder that I know will never let me down?

Perfect. Leaves behind a mess of flux but after cleaning up my joints I feel like a pro.
