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

Use it daily, works great! An excellent choice!

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!

An item that I have used for years and I needed to replenish my supply - you use what you have built-up confidence in!!

Kester, for me, is an old (1889) trusted brand that always has given me consistently good solder connections.

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.

Good product

best solder i have used

Works well for my application

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.

I made the mistake of purchasing 2 because of past experiences with other brands. Usually when you buy these reels, they pad the spool halfway so you think youre getting a full roll of solder when half the roll is plastic filling. Not in this case... you get a full FULL FULLLLLLL roll of solder that lasts longer than most marriages. Im barely halfway through my first roll. Definitely recommended.
