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.

By far the best electronic solder on the planet! I will never purchase anything but this solder for PCB boards! It’s makes the job not only easier but enjoyable. I would recommend it to anyone. When my roll starts to get low I will be purchasing another.

This is top grade solder. It flows very well and is very nice to use. Properly done joints all have a mirror finish.

Flows great, makes for a solid joint.

Now I have no clue if it really performs better than any other solder but it makes me feel warm and fuzzy knowing I used a fancy name brand. It physically solders very well and even a nonprofessional weekend warrior like myself can make beautiful connections.

Absolutely great solder, flows easy, good cleanup, sounds fantastic in my Bottlehead Crack. A clean precise solder for audio applications.

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.

My dad told me this is the best solder ever. You think you know more than my dad, dont buy it then...

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.

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%
