Rosin Core Solder Wire for Electrical Soldering(0.8mm/50g),

Thin and easily manageable for circuit boards and led strip use. Low melting point and strong connection. This is a great product to use and learn to solder with. Securely holds without difficulty and does not run . Very accurate solder points.

Been using this for small electronics work and it’s been performing well. The solder flows nicely and the rosin core does a good job helping the joints wet properly. The 0.8mm size is a good middle ground for most of the soldering I do, from small components to general wiring. My only complaint is the roll size. It’s a 50g spool and I wish they offered a 100g version since I tend to go through it pretty quickly. Other than that it’s been solid quality.

Very decent solder for the price. It flows well enough, and the flux is very easy to clean with just soap and water. Compared to more expensive 63/37 I have used, it's fine enough. Real good stuff will melt like butter the second it touches the tip of of your iron, and while this stuff is decent, it doesnt quite nail that perfect melt. But it's cheap and you can buy it less than a pound at a time. So I'm going to keep buying it. Solid 8/10 usability. Solid 9/10 price. 10/10 clean ability.

This a good quality product. Melts easily and bonds strongly. Did some speaker wires to banana plugs and am quite happy with the result. The price is pretty good too make it a great Value for Money.

This is a great solder for the price. But I've never used 63/37 solder, only 60/40. I experienced a problem, although I can't determine what the cause of the problem was. In my case, on a new circuit board I was soldering, the JWOWO solder climbed up my electrical parts, effectively soldering them, but not wetting out and making a connection to the clean and new PCB circuit board. So, comparing this to Radio Shack and also X-Tronic standard 60/40 solders that have about 2% Flux (X-Tronic is listed at 1.8% Flux and 60/40 ratio of lead) the 63/37 JWOWO had some problems. It may not be the solder that is the problem. But I wanted to report it, nonetheless. I've never seen any of my solders (not even the really bad no-name stuff from Harbor Freight) that didn't stick to a circuit board. I had to actually use the X-Tronic solder because on several solder joints, the JWOWO solder would rapidly wet out and cover a transistor, but none of the solder would actually go onto the PCB. It may have been a temperature problem. It may have been something I did wrong. But I have never seen solder actively resist and not wet out or "tin" a clean PCB that was freshly cleaned with 90% isopropyl alcohol. My advice is to try this, and use it for a specific application. But test it first. I will definitely keep using this solder on copper and tin plated wires, because it flows out beautiful, and works perfectly on wire connections. Just test the solder first, and make sure it works well with the alloys you're soldering. In the future, I'm going to switch to Kester 44 63/37 solder with 3% flux (heavier amount of flux) and see if that makes any difference on the small circuit boards. The JWOWO is 2% flux.
