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

Perfect quality And good product

Wonderful!

great solder

I purchased 3 different rolls of Chinese solder and all 3 were terrible . I will never skimp on solder again . The cost of the 3 were about what 1 roll of the Kester cost . I will be purchasing the Kester brand every time I need solder in the future for my hobbies . There is no comparison in the quality of the solder joints with the Kester being far Superior in Quality , Strength , Ease of Melting and Flowing .

Good solder

Look closely at the flux descriptions for Kester cored solders before buying. No Clean does not mean you dont have to clean up the flux residue. It means the flux does not provide any cleaning action. Kester #44 flux is an active cleaning rosin flux that works to remove oxide from the surfaces being soldered. The solder flows quickly when soldering components in a thru-hole plated PCB, minimizing the time and heat required to obtain a reliable joint. The SN63 version is a eutectic alloy. It goes directly from molten to solid, minimizing the chances of a cold solder joint, at a temperature lower than either tin or lead by itself. I dont worry about the lead, just dont eat while working and wash hands well after handling the raw solder wire. I keep a spool of 0.20 for board work and a spool of 0.31 for chassis connector work on hand. I have never felt the need for fancy boutique solders that cost 4X the price of Kester. Its reliable product that always gets the job done.

This is the best solder I have used. It’s a bit expensive but you get a lot of solder and it makes beautiful joints every time.

It was in a nice roll and works beautifully

Wonderful deal!

I had always used the cheapest solder I could find until I had some instruction from an electronics teacher with some good quality Kester solder. The difference is huge. I had some cheap solder with Chinese writing on it and tried it side by side with the Kester and the ease of use is very noticeable. This stuff melts more easily, flows where it should, and doesnt make those nasty blobs with tails. I had been thinking I was doing something wrong getting ugly solder joints. Turns out crap solder makes crap joints. Kester solder (with the right ratio) makes excellent solder joints.
