Cardas Soldering Wire Quad Eutectic Silver Solder with rosin flux 1/4 lbs (113g) roll

Easy to use solid connection easy to melt silver solder

Too much flux and it stinks.

Pros: Excellent solder found that it melted the best at 350 degrees. I used it mainly for through hole soldering and had very few problems. Flows very smoothly. The silver content is high enough that it conducts very well. This solder reworks extremely well had a couple of fowl ups and had no issue fixing them, Cons: There was a lot of shrink wrap holding the solder together and it took forever to remove. Something that i noticed but was not an issue was the amount of flux that the solder contains internally not terrible just more then i was used to.

I bought this simply because I had ran out of the solder I was using, and based on the recommendation of a video I had watched on youtube which was a tutorial for soldering techniques. They recommended silver solder with a rosin flux, and this just so happend to be the best price to quantity ratio I found on amazon. I had to fix some bad joints on my guitar, a stratocaster, and got the chance to try this solder out. As many have said, it heats at a lower temperature than lower-grade solder, as well as flows much, much better. If I can help it Ill be purchasing this solder again in the future for my guitar related needs.

Im not the sort that subscribes to Cardas audiophile nonsense marketing ploys, but this solder is genuinely fantastic. It wets the first time, every time, and produces clean and solid joints every time. Surface mount, through-hole, point to point, doesnt matter, it does exactly what you tell it to each and every time. I use it for everything, because the sheer consistency and cleanliness it provides is invaluable for any electrical work. The melting point is a bit low for higher temperature applications, but for general consumer electronics it simply does not get better than this. I spent years of my life believing that I was simply bad at soldering, and that it was something I could never get good at -- and then my boyfriend gave me a roll of this. Have never bought anything else since.

Good product, but rosin smell is unpleasant to me. Will probably go back to Wonder Solder.

Flows great, makes for a solid joint.

Perfect! This is just what I needed. Thanks!

This solder is amazing, I used this to join a connection of 2/0 battery cables, and this did the job very well. I was pleased at the rather low temp this solder flowed into the center of the connection. And how well the the joint looked after it cooled. Cleaned up very well and allowed the heat shrink tubing to lay nicely over the connection. I will always make sure to have some of this on hand.

I have probably soldered close to 1,000,000 electronic circuits and tens of thousands of custom fabricated hobby craft joints in my life. The reliable old 60-40 solder served me well on electronic circuits and then the stronger silver-content solder worked well for craft work. But the silver solder I used for craft work was very high heat and if I tried using it on electronic circuits it more often than not destroyed the delicate copper traces on expensive circuit boards. The Cardas product is a quality silver-based solder that melts at far more reasonable - although still quite high - temperature and provides stronger and IMHO better sounding connection than 60-40 solder does. Simply re-sweating any existing soldered electronic joint may yield audible improvements providing that the components being soldered can tolerate this higher heat [i.e., used with caution on temperature-sensitive and surface-mount devices]. Will this ALWAYS make things sound better? Probably not. But heres the way I look at it. Eliminating problems in the long audio chain between the signal source and your ears is a tedious process. If you have a particular piece of gear already in pieces on your bench, why not eliminate a potentially weak-ink in the audio chain by using better solder? The cost is small and the return could be large. If you always do what youve done, you will always get what you got. If you want something different, then you must try something new. Give this a try; Im pretty sure that it will surprise you.
