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

My old solder was from the 1970s, but I was having issues with it not flowing cleanly. I decided to try a newer roll, which has the same specs. For some reason, this one performs better.

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.

Lead - yum. It works well.

I had never used 63/37 solder before. I always bought normal brand 60/40 rolls. This solder takes me to a whole new level. It melts at a lower temperature. It is very thin and thus more suited to the precise joining jobs that new electronics require. I had to practice before I could reliably control this thin stuff, but my effort was rewarded. It is more expensive than the normal solder, but worth it to me.

A little bit higher melting point than I wanted. Nonetheless a good solder.

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.

Good Solder -

Use this daily as an audio professional!

Loved the small diameter for small components and quick melting point,have been soldering since 1964,this is the best yet.

Excelent product
