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

With regular 60/40 solder, the solder undergoes a plastic period where its not entirely a liquid and not entirely a hard solid. If you bump or wiggle the joint in this plastic period, it ruins the joint. Save yourself the hassle by just getting this formulation which more or less eliminates the issue. Bump to your hearts content.

Have been using that brand for years and once my old supply ran out, I got a new roll and it was just as high quality as the old ones.

Great for small connectors and fine wires. Just have a worth while solder device...and not something from a discount store that only gets warm and doesnt heat.

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

Very nice quality, Fast shipping, Thank you for everything.

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.

Have nothing to say cause I have used it before at my work place.

easier to use than the cheaper lead free solder

This is the best stuff you can get and for a fraction of the price.

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
