Liquid Solder--Does It Work? (4K)

- Two different types of conductive liquids. Between the both of them, they cost as much as a soldering iron and roll of solder! The copper one is less expensive. They claim to be for creating and/or repairing electrical connections. One is a thin copper based mixture, the other is supposed to be silver nano-particles. I always wanted to test them to see if the are a viable alternative to soldering, especially with small or delicate parts.
To be useful, they have to have some degree of 1) the electrical conductivity of solder, and 2) the mechanical strength of solder.
We shall see.
Thanks for the neat experiment. I have never used any of those products before because I learned how to solder when I was about 10 or 11 years old. I think I will stick with the soldering iron.
I'll be sticking with soldering also. I was hoping this would be the answer to tiny solder jobs, to counter unsteady hands.
@@tsbrownie I think you did a great job but it seems that technology has'nt caught up with heatless solder or the high tech version has not been released to the public yet.
@@adnacraigo6590 Thank you. If there's industrial quality stuff out there, I haven't found it. The silver one is supposed to be, but it falls way short.
I have worked with copper tape and came to the conclusion that, with proper techniques, a very robust, low-voltage circuit can be developed. As far as robust, more robust than a breadboard circuit, but less than a perf board circuit. The process is much faster than both of these traditional techniques. I used copper tape on foam board. I attached an enlarged photo copy of the schematic to the board and laid the circuit out directly on top of it, so no mistakes. I pierced the tape to allow the component pins to seat in the foam, for stability. (Use a fine needle and do not drive it too deeply into the foam.) If you want to insulate the copper tape, cover it with clear package/scotch tape. (I did not bother.) I was not trying to avoid soldering, so I soldered the pins to the tape and all the tape joints. Maybe the copper ink would do for that purpose. Wire nuts could be used to make twisted wire connections. It might be a fun adventure to try to wind a coil with copper tape, separated with scotch tape. But, I think it would be difficult to remove the section of clear tape to make contact with a tuning bar. Cheers.
Copper tape is not bad. I've used it to create grounds between different parts, like covers. I have no doubt that it would make a good circuit, especially if the junctions were soldered/jumpered. I thought about winding my variometer with copper tape, but trying to get a wire to stick to it is hard enough, a wide flat tape with no edge insulation would be a nightmare!
Hi 👋😃
I've tryed the "conductive glue" to glue ICs, LEDs etc. to copper tape for making interactive paper cards and such but like in your test it was BS imao! I used a heat gun but the seller told me I had to bake it in the oven but that wouldn't work with the tape and the paper. Soldering is the only way so far :(
The only thing those conductive paint pens might be good for is to repair a small/hairline break in the conductive wires on car windscreens for a demister or radio antenna. The mechanical strength would be provided by the non-flexing glass itself, the conductive printed wire ends aren't going to move either. Once dried, it would have some level of permanency, allowing you to wipe the glass without removing or damaging the repair. For a touch of resilience, a small coat of clear nail polish over the top would seal and protect the repair.
I don't understand the statement " people who don't solder" my neighbor said that to me one day while asking for my help on a project he was doing. I offered to teach him. But he refused my offer, I've done several jobs for him involving soldering that he could have done himself in minutes
I hear you. I was forced to learn by an older brother at 6; my fear of him was > fear of the soldering iron. ;)
I sometimes just use aluminium foil with some tape
You do have a REL function on that meter.
Yes, good point. I was just being quick and dirty.
@@tsbrownie Yeah, no worries, just making an observation. I've also found that liquid solder stuff to be useless for anything I can think of. I used to know a guy that did automotive wiring using a liquid solder, twisting and electrical tape. I wonder if one of his creations ever ended up in flames?
@@uni-byte I've seen more than one car burn because of dodgy wiring. The liquid solder I tested would probably have helped ignite a fire. ;(
@@tsbrownieLiquid solder use is new anyhow. These fluids are around as a repair solution since heated rear windows got on the market. Who would have thought to replace solder with that stuff ?
This liquid solder would be used on electric generator rotors as a repair solution. The wiring connection is copper clad aluminum. It does not hot solder well. This is a common failure on a gas electric generator.
Interesting. Thanks.
Sorry I might have not understood what you are trying to do but you was using solding paste without a soldering iron (heat source), soldering paste is usually used for smd, you can use it with a solding iron or a hot air ghun, its not suppose to act like a glue, basically you apply a tiny amount and the heat fuse the metal together. the advantage of the solder paste is its got beter capillary action than roll solder
I was using a liquid solder that is microgranuals of metals like silver in a conductive glue. It is recommended for that and to replace broken tracings. It's very expensive and does not work well.
@@tsbrownie ok.the tube looked like solder paste
you need another twisted wires without glue/substance for comparison
That would have been better. I have done that comparison when using regular solder and the result is that a clean twisted copper joint INITIALLY has about the same resistance as the copper wire. Of course over time the resistance increases as the copper corrodes. With regular solder that change in resistance is very low.
Why should one go into electronics, who doesn't like to solder ?
That doesn't fit together.
It's not a safe solution for kids either.
