Well scripted, professional presentation, no heat, and no caustic liquids puts your technique at the top of the priority list. Especially appreciate your showing the resistance readings for the first layers of the traces. A typical resistance reading across such a short should be well under 100 milli-Ohms. Maybe 3 layers would achieve that. Thanks for the very cool technique
Amazing! Gonna try that right away! (My pcb exposer got swamped in a flooding earlier this year...) Also, you could probably galvanize on some copper at this point. I'll try some stuff and report back.
That's really cool! I'm just learning electronics and sometimes I wish I could just produce a circuit board. May have to look into a laser printer now.
@@rosebarnes9625 true, problem with liquid electrical tape is it's not heat resistant and is going to screw with soldering... If you could hole-punch kapton tape maybe?
This is awesome. I will definitely try this next time I have a membrane switch panel to repair. Always wondered why there cannot be a conductive inkjet printer.... this will work until then.
Very impressive and many process to do PCB without etching .One serious dangerous effect : Silver Poisoning ! The End product should coverup with transparent Perspeks or glass for artistic noncontact display .Good job done
Have you tried covering not only the solder pads, but all the traces with the solder paste to get stronger/lower resistance traces? (Similar idea to allowing solder wave to add solder to exposed power traces for higher current capacity.) Oops... just noticed how old this video is... Not really expecting an answer. ;-)
You could use the toner transfer method to transfer the ink traces to a solid surface, and then use your steps to apply the silver glue. This will also remove your "browning" health hazard :P. Very nice work. This method should be used and explored more!
Perhaps check out NileRed's The Silver mirror and Tollen's test. There might be something to using traces, with silver deposition for more permanent results.
i do armor costumes and prop replicas and this technique will be very useful for making a full armor suit power harness if the conductivity can be made high enough and a non conductive layer placed over the printed traces. all i would have to to is add a short wire connector between the parts of the armor with a central power supply and have this all along the inside of the armor
VERY cool! I love the super high quality traces and pads you get, it really blows away conventional toner transfer method. Looks like it’s more suited for small, low power circuits though. How much was the silver paste, and where did you get it from?
It is equally suited to large high-power circuits you just have to modify the traces make them thicker and wider of course no different than copper traces.
I would love to have that flashing light circuit you made,with smd parts,it would be a fun kit,trust me they have kits out there ,that are less interesting,that could be a conversation piece..
Great video, I was intrigued by the process and had to try this out but unfortunately I had no success. I had to work with what I had and here are some notes if you ant to try this: 1) I used a version of the AA-DUCT 906 paste that comes in a pouch, this package has you mix a reagent with the paste to make it malleable. I followed the instructions but the paste seamed a little too thick and couldn't get it to bond with the paper ink. 2) The paper I used was CANNON "photo paper glossy" and if you heat it too much it does not get brown, instead it pops the top glossy part and the ink doesn't seem to be affected. This behavior is different from the one in the video. 3) I used a EPSON ET-2650 so maybe it has to do with the issue. Again great video and good luck to whomever tries this method
Awesome. You inspired me something a bit different. What if you lay a gold fold on tracks a warm it.. Maybe it will glue on ink too. I ve seen gold foils on Ebay for 15$. Could be worth it.
That seems like it would leave you with a similar thing to what you might find in a computer keyboard. Some of them have a couple layers of plastic with traces made of something that might be similar. Also some computer mice may have plastic like that found in a keyboard. I think they mostly use it there because it is flexible and cheaper to use but not so cheap that it doesn't last long which is a downside of a lot of low cost stuff.
Subed ;) can you think of other stronger materials than silver that would apply the same method. Also do you think this method can be applied using 3d printers as in automated solution?
Nice silver plating, but if it's not durable like you say for flexible circuits it's no go then. For simple PCB this seems way better, and simple. Heatless (cold) Toner Transfer (for PCB)
while it's possible to get traces that look good on kapton (and other non-porous materials) - they don't seem to cure to the point of conducting. it seems the inkjet paper assists in curing (I'm guessing the resin in the silver paste somehow gets sucked into the paper through the toner).
@Blondie SL so someone should make a laser driver with this. lm317 based where the resistance plays a big role in wether your laser will emit light. or smoke
At 4.46, the pad on the right looks like it has a crack in the silver trace. Or is that just a "dribble" of the solder paste? Can't tell for sure. Didn't seem to flow with the hot air on it the way the dab of paste did..??.......
maybe you can use a fuser assembly from an laser printer to precisely heat/ cure the silver glue. the fuser is coated with Teflon, and should work fine. adjusting its speed and temperature would give uniform and pepper cure every time.
well if your measuring resistance you want to be touching a large surface area to be sure of what resistance the trace is. put a tiny solder blob on two of the PCB pads one on each end and cure it. then check measurement again measuring right on top of each solder point. rather than the PCB. You should see the resistance is enormously lower.
Question...could you use an iron, and imprint the printing on a copperless PCB board, then apply the silver glue? This way the circuit is already applied to a solid substrate?
I've tried this - and while you get silver traces - the glue doesn't seem to conduct. it seems like the silver paste's curing to a conductive level is somehow assisted by the photo paper. I'm betting the resin actually gets pulled through the paper into the toner. tried this with a number of other non-photo-paper materials (like acetate sheet) with same results.
Well scripted, professional presentation, no heat, and no caustic liquids puts your technique at the top of the priority list. Especially appreciate your showing the resistance readings for the first layers of the traces. A typical resistance reading across such a short should be well under 100 milli-Ohms.

This is a awesome idea, thank you so much for sharing your discovery with the community! Have a great weekend :D
that must be the most expensive blinking LED in the universe
Great idea! I can really see this tech improving to a more pro prototyping, and fast too. Thanks!
Now thats a thing of beauty ... well done!
Ill give that a go at some point, looks interesting
Amazing! Gonna try that right away! (My pcb exposer got swamped in a flooding earlier this year...) Also, you could probably galvanize on some copper at this point. I'll try some stuff and report back.
That's really cool! I'm just learning electronics and sometimes I wish I could just produce a circuit board. May have to look into a laser printer now.
Surprised I just came across this. So far I really like this method quite a bit. Thanks for sharing.
I really like this, hate the chemicals mess of traditional board developing, this is very clean and very nice. Thanks for sharing.
One is never too cool to learn something new. One idea may lead to another and another, etc. Thanks for posting.
Good job sir. Please keep making this this sort of intriguing videos. Wish they taught me this back in school... Subscribed.
That's impressive Rich, nice job.
it would be interesting to try and make multilayer board this way!, punch vias in the paper, dab some solder, and keep stacking it!
As long as it's low voltage... paper is not a very good insulator.... maybe use liquid electrical tape as the glue between layers...
@@rosebarnes9625 true, problem with liquid electrical tape is it's not heat resistant and is going to screw with soldering... If you could hole-punch kapton tape maybe?
@@Rx7man well, don't solder the components down...... staple them! 🤣🤣🤣
Yeah, I don't know...
This is awesome. I will definitely try this next time I have a membrane switch panel to repair. Always wondered why there cannot be a conductive inkjet printer.... this will work until then.
NICE! thank you for showing us your wonderful research
Very impressive and many process to do PCB without etching .One serious dangerous effect : Silver Poisoning ! The End product should coverup with transparent Perspeks or glass for artistic noncontact display .Good job done
This is a different way of PCB making without etching, Nice

Added to my favourites list. Thanks!
Excellent piece of experimenting, with a great end result. Thanks for sharing.

I wonder if you could electrolyze the traces thicker. Of course, then you possibly just may as well go the other way.
If you're going to the effort of preparing Tollen's reagent, then you might as well just etch copper -- the standard approach.
what it is based on, ferrum sulfide?
drill usage
wow what a neat project! Thanks for posting this, I'd love to try this sometime, but I think my ventilation is not good enough to do this inside...
Great technique! I'm gonna try it for custom membrane keypads. Thanks for sharing. Link to the solder paste ?
Looks good for quick prototyping. Will try this method someday.
Oh. My. Gosh. This is sooooo amazing! All etching trys dont realy turn out good but with this... Oh my!
very clever well done and thanks for sharing
Excellent work, I will try this experiment for sure, thanks for sharing.
that is some beautiful work broth!
wow, really a great method for making circuit that eliminates the use of those highly acidic chemicals.
THIS IS GREAT!! a layer of epoxy on top might help protect traces
This idea is worthy of a Nobel Prize)
Great demo! thank you for sharing.
Very clever solution especially for home use by guys which are fond of electronics.
That's awsome! Thanks for share this experience. Best regards. Luis T.
..wow well done man, very impressive!!
I was skeptical, but you're right, that does look to be a useful method for making prototype static flex PCBs at home
if you flex it the silver trace will break
Great idea, if I get a chance I'll try this.
i do armor costumes and prop replicas and this technique will be very useful for making a full armor suit power harness if the conductivity can be made high enough and a non conductive layer placed over the printed traces. all i would have to to is add a short wire connector between the parts of the armor with a central power supply and have this all along the inside of the armor
Wow. Great idea. Thanks for sharing.
Low temperature solder paste for rice grain sized components and a heat gun. (slaps forehead) You just solved a problem I have had for a while.
VERY cool! I love the super high quality traces and pads you get, it really blows away conventional toner transfer method. Looks like it’s more suited for small, low power circuits though. How much was the silver paste, and where did you get it from?
It is equally suited to large high-power circuits you just have to modify the traces make them thicker and wider of course no different than copper traces.
That's just plain clever.
Can you use a very miniature tiny slip of paper between layers to make bridges???
I wonder if the silver trace could be coated in solder for durability, then solder masked to assist in soldering the parts down.
Awesome! Thanks for sharing.
I would love to have that flashing light circuit you made,with smd parts,it would be a fun kit,trust me they have kits out there ,that are less interesting,that could be a conversation piece..
You WHAT? This is so awesome!
Thanks for the video.....VERY interesting. Now I'm wondering why can't I do the same thing for 1/35th scale gates, fences, etc.?
This is a awesome idea Thak you for sharing
Super job, well done
Thx a lot for this tutorial. Salute
Clever. I like your method.
now thats really cool.. and i just happened to purchase a laserprinter.. :)
Awesome resolution compared to printing on transparency and then contact printing pre sensitized pcb material.
Excellent idea. I like that you got +1 like and subscribe. Good work
Great video, I was intrigued by the process and had to try this out but unfortunately I had no success.

Again great video and good luck to whomever tries this method
It didn't work because you used an ET-2650 which is an Inkjet Printer - this requires a Laser Printer as the silver adhesive sticks to the toner.
Awesome. You inspired me something a bit different. What if you lay a gold fold on tracks a warm it.. Maybe it will glue on ink too. I ve seen gold foils on Ebay for 15$. Could be worth it.
What steps would you recommend if I wanted to try this method using a reflow oven? Great video, by the way! Liked + Subbed.
amazing...
if you want a lower resistance for traces add more layers...
That seems like it would leave you with a similar thing to what you might find in a computer keyboard. Some of them have a couple layers of plastic with traces made of something that might be similar. Also some computer mice may have plastic like that found in a keyboard. I think they mostly use it there because it is flexible and cheaper to use but not so cheap that it doesn't last long which is a downside of a lot of low cost stuff.
might be ok for wearables after applying some heavy protection :)
brilliant, good work
Very cool. Thanks!
very interesting way to approach it
I imagine it may be quite fragile. But that is a truly beautiful idea.
It might be a good idea to coat the final in some clear coat
what kind of resistance do you get if you apply 3 or 4 layers? This is an absolute game changer.
Subed ;) can you think of other stronger materials than silver that would apply the same method. Also do you think this method can be applied using 3d printers as in automated solution?
Nice silver plating, but if it's not durable like you say for flexible circuits it's no go then. For simple PCB this seems way better, and simple. Heatless (cold) Toner Transfer (for PCB)
I wonder if I can just use a hair dryer for the heated things and Microsoft paint for the circuit print wires. Everything else will be the same.
Great info!
Can you print the circuit on Kapton tape (heat resistant) for greater durability, to make flat-flex circuits?
while it's possible to get traces that look good on kapton (and other non-porous materials) - they don't seem to cure to the point of conducting. it seems the inkjet paper assists in curing (I'm guessing the resin in the silver paste somehow gets sucked into the paper through the toner).
That is AWESOME!
This is brilliant. This would save me so much hassle when making prototype boards. Just make a quick test on friggin' paper! I could kiss you XD
pretty impressive
Awesome idea!
exelente método amigo me sorprendes , pero como quitas del papel el circuíto ?
Very cool indeed.
What sorcery is this?!
@Blondie SL so someone should make a laser driver with this. lm317 based where the resistance plays a big role in wether your laser will emit light. or smoke
Anti lycan theft
Just the usual sorcery, magic smoke enabled FM!!! 🤣🤣🤣
will copper paste work as well?
Can you heat transfer the toner the old fashioned way on to a PCB blank, then follow the exact same process, but on the blank?
That is awesome stuff
At 4.46, the pad on the right looks like it has a crack in the silver trace.
Or is that just a "dribble" of the solder paste? Can't tell for sure. Didn't
seem to flow with the hot air on it the way the dab of paste did..??.......

Really cool!
Very nice!
Can this be done with transparent sheets for overhead projectors instead of paper?
What is the silver pest. Please send name. Naice video am happy
I wonder if there are replacements for the silver.
well if your measuring resistance you want to be touching a large surface area to be sure of what resistance the trace is.
put a tiny solder blob on two of the PCB pads one on each end and cure it. then check measurement again measuring right on top of each solder point. rather than the PCB.
You should see the resistance is enormously lower.
this way is very good。but what is the paper？
While not really practical (and probably much more expensive than etching), I do give a thumb up to innovation.
Thank you.
thats innovative
Next project, paperuino :)
Very very cool! Wow
If you tinned the traces, maybe the conductivity of traces would improve?
Great idea.
Surely some plastic overhead projector type paper is better ???? Good idea....
If you're browning glossy paper (clay coated) you're gonna turn plastic into a liquid - if you're lucky. Decomposition can be nastier yet.
What any the PCB or circuit with component mounting like caps, desi, is etc
Excellent!
Question...could you use an iron, and imprint the printing on a copperless PCB board, then apply the silver glue? This way the circuit is already applied to a solid substrate?
I've tried this - and while you get silver traces - the glue doesn't seem to conduct. it seems like the silver paste's curing to a conductive level is somehow assisted by the photo paper.
