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

Da bomb! Great solder and surprisingly decent price compared to similar quality solder such as kestler, considering that the Cardas brand usually comes with a silly audiophile premium price. It’s very thin, but if you need thicker just twist it together into a thicker braid.

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.

As a ASEET electronics tech I been soldering for 40 years. This is easily the best solder Ive used. The flow out is fantastic and makes a cold solder joint impossible unless you screw up from a lack of solder skills. The silver content is perfect and is proven by the bright silver color of the joints and testing a 5 foot length with an ohm meter against the other brands. The Cardas shows the lowest resistance of any solder out there. Clean the soldered joint with a q tip and alcohol to see the proof. I add a dab of rosin flux on old solder joints with unknown solder and this solder flows and blends perfectly.

the best in the west by my test

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.

Perfect! This is just what I needed. Thanks!

Great stuff. Always stays shiny and the audible difference is there.

This is the best flowing solder I have ever used. Been a tech for 50 years, and this solder flows perfectly in through hole plating on PCBs

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.

This is the best silver solder Ive ever worked with. Normally silver solder is tricky since it doesnt flow or stick as easy as typical lead solder. But this works very nice. I also enjoy the thin size so you can easily position it up and over items. It has an odor to it that is unlike any other solder. Its hard to explain... maybe if you were to mix metal and a strawberry together.
