best solder i have used

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!

This is a really easy solder to use, its now my preffered one for repairs etc...

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.

Handy package quality item and brand

This has been my standard solder for the past year. Couple this with no clean flux and your set for most small/medium soldering projects.

Its solder, its Kester. Not much more you need to know.

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.
