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

What can anyone say? I have been soldering for many years and this is the best solder I have ever used.

I have used a variety of solders over the years. Problems using the wrong solder can include the following: poor connections and brittleness, difficulty with heating the solder to the right temperature, especially if it contains the wrong combination of ingredients... which many do for the average user. This Eutectic Cardas solder melts fast, heats well, gives you nice connections... its just easy to use and very effective: Yes it costs more, but its soooo well worth it! Sheerness? What are they asking you to say here? I dont know.

Flows great, makes for a solid joint.

A friend turned me on to Cardas solder when I began building my own microphone preamps for my recording console. The solder that you use is part of the signal chain and an important factor in these types of builds so I wanted top notch solder and I got it. It came very quickly and after my first use i was really impressed! You cant go wrong with Cardas. Its the best in my opinion. Money well spent!

What can I say, Cardas Quad Eutectic solder is by far the BEST out there. Hands down, I’ve tried them all. From cheap hobby store “silver solder” to the most expensive boutique brands. I restore/repair/upgrade/design Hi end Audio gear. Names like MCIntosh, Conrad Johnson, Cary, etc. equiptment that rivals cars in price sometimes. I need the best. Cardas is it. If you don’t understand the meaning/science behind Euctectic solder, look into it, the more you know. Great for beginners to start with, it’s very very easy to work with. Leaving perfect shiny solid solder work. I see a lot of “amateur soldering” and let me tell you. Most people who “can solder”, can’t. Make sure to use the correct iron, temp and procedure for your work. Also, a solid mechanical connection is always required. Wrap your wire/leads at least once. Use terminals or solder tags, and make sure nothing moves while the solder sets. I see so many cracked, failed, cold solder joints. Also with the Vintage gear becoming popular and everyone being a tech now and “re-capping”, I’m amazed some of these pieces of gear still work. People, just touching the two ends and soldering is not enough. J-hook or use a terminal to join. The joint should be sufficient even WITHOUT solder. The solder should only be needed to “lock” the mechanical joint once hardened. This stuff hardens equally across the metal combo, making for an incredibly safe, solid, secure joint. Ive used Cardas for over a decade and never an issue with a cold solder. I buy the 1lb rolls quite a bit as I use so much. However, a single $30 roll will last the normal hobbiest a lifetime. Nice and thin making waste less of an issue. Again, if you’re going to get into serious work in audio gear. Use Cardas quad eutectic and a good adjustable solder station. Hakko makes a great rig for $100 on Amazon. You can’t beat it At the price and will last a lifetime. Realize PCB and point to Point applications require a much different approach. (Temp) Also, those recapping x-overs, use a heat sink(2-4$) to protect those expensive new caps. Leads heat up quickly and most noobs aren’t quick with an iron. Less is more, both in time heating and solder used. Finally, remember that a shiny joint is needed. Re-due bad solders than and there. Don’t wait til they’re a problem. With what people spend on caps and wire, spring for good solder. Cardas is a real player in the metallurgy game for a long time, fortunately for us audio heads. ***no affiliation at all to Cardas. Usually I don’t post positive reviews. When it’s needed it’s needed.

I only use this, put away my wonder solder along time ago, and recently compared them again, with the benefit of experience. Wow. The only solder.

I needed something that sounded better than regular solder. This is the best sounding solder Ive found. If you care about audio buy this solder. It is a littler harder to use, however it will be worth the price and effects. Once you hear the fine details in your music you will not go back to regular solder.

Ive used multiple brands/types of solder, and this is my favorite so far. Ive used it on guitar pedals, reel to reel machines, guitars, amps, and even small SMD work. It works great! great bondage with a shiny end result every time. Would recommend 100%

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.

This works great in all situations. Maybe there are other solders that are this good? But when audio fidelity is important, it never lets me down. Highly recommended for musical instrument assembly, audiophile cables, and anywhere else where you expect it to work perfectly forever.
