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

Ive tried other brands, Kester is the best. For almost 30 years Ive used this brand and cannot say enough good things about this solder.

Best solder for racing drone applications

Live this stuff. Great for FPV hobbyist.

Best quality solder Ive ever used.

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.

Very good solder

Ive had a small spool of this stuff that I found in the trash at work. solders nice, but I ran out. This will be a lifetime supply for me.

What is there to say? It’s Kester solder, it speaks for itself.

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.

This solder is very easy to work with, but to make it No-Clean as advertised, they use much less flux than regular solder. What this means is after you apply the solder for the first time, the small amount of flux dissipates, and youre left with dry solder thats very stringy and hard to work with, and youll need to apply your own flux to work with it again. That said, as long as you dont need to fix anything, this is still a very nice solder to work with.
