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

Using this stuff for audio cables and it works really well. Melts predictably and holds strong.

Dont let the slightly higher price scare you away. After the first use, youll understand why is more expensive.

I typically use another formula of Kester solder. Decided to give this a try. It works very much like more common Kester solder. I noticed much less residue. It seems to have a slightly higher melting point and a bit less flow (I do through-hole components). The difference is small and the decreased residue is a real plus.

If youre like me, you might think youre a noob at soldering. Again and again, I lift pads, make dull joints, and just overall have a crappy, frustrating time doing soldering jobs. Then I took a long hard look at the tools I was using... my iron was fine, a Hakko FX-888D. Probably the best in the business, for a casual home solderer. Next is the solder itself... Lead-free rosin core. Hmmm, could this be the problem? After getting this 63-37 leaded solder, I can most definitively say: yes, lead-free IS the problem. Love the lead. Live the lead. After finishing up a soldering job for the balance plug of a 2S Lipo (FPV quads, if anyone was interested), I looked at the joint and I was wowed at such a good job I did. Or rather, such a good job the leaded solder did. Shiny, flawless, just perfect. Live the lead! Lose the lead-free!

As I am getting reaquainted with electronics I remember how great Kester flows. Cant go wrong!

good product

Its fine. It does what good solder should do.

Excelent product

Does NOT flow well, like Kester rosin core solder does, unless your leads are pre-tinned or you use separate flux. Ill be tossing this now that Ive verified the OTHER Kester is the GOOD one:

Use it daily, works great! An excellent choice!
