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

Works great for clean copper only. If you have slightly dirty surface you must use a stronger rosin then what is this. I love the option. If this doesnt stick I add a little Flux and clean after I solder. If it a clean surface I just use this and dont clean. Works great this way for.me.

I had never used 63/37 solder before. I always bought normal brand 60/40 rolls. This solder takes me to a whole new level. It melts at a lower temperature. It is very thin and thus more suited to the precise joining jobs that new electronics require. I had to practice before I could reliably control this thin stuff, but my effort was rewarded. It is more expensive than the normal solder, but worth it to me.

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

Limited use so far, but did exactly what I needed.

It’s solder. It has resin. It flows and makes connections. Isn’t solder pretty much a 1-star or 5-star thing? Is there artisanal solder that I’m missing out on? This stuff works, and it works very well. Buy it.

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.

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.

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.

When you need something that works, get this.
