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

No splatter, easy flow, cools right... connections are always solid. Great stuff!

Great quality .Why risk your electronic assemblies to anything less?

This solder is great. The rosen core really helps. It flows smoothly and clean. Highly recommended.

It does what it is supposed to.

GREAT FLOW AND GREAT DEAL.

Excellent solder. In my opinion, it’s better than the tried and true standard rosin. The activated rosin is a stronger flux, which allows to use a lot less in the core than standard rosin. So not only it works slightly better, but it leaves much less of a mess than standard rosin behind. You can hardly notice it. Truly no clean needed.

Best solder on the market for both general soldering projects and also small detailed electronics.

Best solder I’ve found when working with simple circuit board applications. Doesn’t smell horrible and is very easy to flow without a lot of gross flux. Have been using this for years. Worth it.

Melt fast and flows nicely, I have been wondering why some of my solder flow nicely and some dont, before I place my order for my re-supply, I looked at the spools and found out I have 60/40 and 63/37 solders, the 63/37 are the one the flow nicely. This is a little more expensive but worth the money to eliminate some soldering problems.

What can you say? Narrow gauge, good for electronics. Ive been using Kester for 50 years, as long as they havent changed the formula it should be fine
