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

Works well, flows good no contamination

Way better than the old 60/40 stuff. This solder is great for through-hole use. Great diameter which is small enough to be precise on some of the finer soldering jobs out there, such as soldering headers to a Nano. It flows and bonds great. Other than possibly trying a lead-free solder, this will be my go-to solder for years to come.

good

Great

Ive always had a hard time soldering. I have tried many varieties of solder and flux as well as different irons/guns. I just figured thats how it was. I just used this Kester 63/37 today along with some new Rubyfluid soldering paste and wow, night and day difference. Just finished repairing several broken wires in a automotive wiring harness and I actually enjoyed the soldering work this time. This solder melts quick and flows nice. Its expensive but worth every penny.

The real deal, accept no substitutes

This is a full 1 pound spool of Kesters most popular leaded solder for general electronics use. The 0.031 diameter is small enough for working with most PCB components while still big enough for easy general electronics wiring projects.

Excellent Solder. Ive used all types of solder, from the cheap Chinese stuff, to the smaller rolls that you can get at your local home improvement store, and this stuff is the best. Dont get me wrong, the other stuff can work well, but this has the lowest melting point that I have ever dealt with, and the joints it makes are all shiny and clean, though you will need to clean off extra flux once you are done.

Very good product, a little more than i wanted to spend. But happy with the product.
