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

Dont get the cheap stuff. This spool is very high quality and easier to use than the cheaper solders and the joints also come out shinier.

I made some research before ordering and found that Kester seems to be the brand to go for. I was tempted by cheaper products from others but in the end I did go for Kester 245 no-clean core solder 63/37. I am soldering not too much and wouldnt call me a professional but even as a hobbyist I noticed a difference between cheaper 60/40 I had before and this one. I am not sure if that is because of the 63/37 grade or because my previous stuff was from some unknown manufacturer but in the end I dont care. I feel it was the right decision to go with the Kester product. It works for me well.

Great solder. Got some perfect shiny joints.

The only solder I ever use on my drones. Nice, shiny solder joints every time!

This solder is great. The rosen core really helps. It flows smoothly and clean. Highly recommended.

Excellent quality solder for the price. Better than 60/40 because it solidifies a lot quicker, making it less likely to form a cold joint. I had some flow issues while using this to replace capacitors on a flickering monitor so I also bought a jar of

Kester always produces excellent product, & this has been no exception. Keep it up! Thank you!

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.

Good Solder -

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!
