In this video I will be having a closer look at conductive ink pens and find out whether they are useful when it comes to creating electronics circuits. I will test 2 different types by doing an experiment targeting the resistance, current capability and frequency response. At the end we will know for certain in which way such conductive ink pens can be used.

I think we can print (badly) with copper already (and it's super difficult) but it's not your standard FDM printing on account of needing ~1200 degrees to melt the copper. I think it uses powered copper and laser instead. I like you am super excited to see a day when we can print copper (hobbyist style) esp if you can print it inside a standard print.

@simplywonderful449 2 жыл бұрын

Since conductive 3D printer "ink" is already available, you can now quite literally "print" printed circuits using a 3D printer. I'm not aware of any standard inkjet printer ink that is conductive to this degree, though the problem with standard inkjets is that you can't "feed" a rigid surface through them, but you CAN 3D print on a thin board, for example.

Sometimes I've made double sided DIY PCBs using photo-resist and copper clad etc. This works nicely, but one issue is that the top/bottom vias are not connected after drilling them out. To solve this, I typically insert thin wires in all the vias, and solder on both sides ... but this can be a bit tedious. I wonder if this 'magic' conductive ink might be used to quickly plate the vias, by injecting it into the holes. If so, this ink might possibly be useful for 'actual' projects.

These came on to the market some time around the late 1970s and early 1980s. Their specified intention was for circuit board repair. This was at a time before surface mount circuits. The smallest trace found on most PC boards was 0.1 inch which is the pad width for through-mount ICs. The only method of creating a PC board at that time, whether mass produced or hobbyist was a photographic process, and using caustic etching solutions to process the copper. Making a PCB as a hobbyist was possible, but more involved than many wanted to go into. The first PCB pens were actually black ink pens used to draw opaque traces on the transparent acetate to hand draw the photo positive for that photo process, and it actually worked pretty well for that purpose. The carbon based black ink in these pens was discovered to be conductive, and so the birth of this whole idea of just drawing the PCB directly.

@CXensation 3 жыл бұрын

I prefer the oldschool readymade hole or holestrip pattern PCB's for a quick prototype build. They are conveniently laid out with a 0.1" hole pattern fits leaded type IC's and all types leaded components. You can even use these PCB's as an overlay for cardboards and then with a nail or needle punch your hole pattern on to the cardboard. That makes for a very neat birds nest on the initial layout. You can always order from JLC pcb maker later on for your deluxe version project.

I use conductive paints and inks to replace acid destroyed circuit traces on my old Soviet quartz watches. Its actually pretty good and instead of all that soldering minute bits of wire onto a circuit board I just paint over the break and jobs a good 'un. I started using originally silver paint used for repairing the fine traces in rear screen demisters for your car, using that to create overclocking and unlocking bridges on AMD and Intel CPU's and was always useful for repairing a circuit board where a capacitor had let go or a coin battery had sprayed its love inside the device.

Great Scott! Can you test if you can use that ink pen to do temporary connections on perforated laminate board? I mean the prototype pcb full of holes in which you need to make connections yourself but you can solder to it easily. If that silver would stick to that pcb enough to make connections, it might be a fairly sturdy and cheap alternative to breadboard in which you can solder the components, but make the connections with pen. It is always a pain to make connections on those boards, so maybe this pen will do the job. Also, test this also with the cheaper black pen which uses graphite instead of silver. Because the copper lining of holes in that pcb willl enhance conductivity and you need only to make conduction between them, so maybe even black pen will work.

I recommend the cheapest silver conductive ink you can find that is more of a paste. squirt that onto a piece of plastic. now get a tiny tiny sewing needle and screw that into your exacto knife instead of the knife. now use the needle as a paintbrush to finely paint traces with amazing accuracy with this this paste into your substrate of choice. don't stop the trace shy of a component! set that component DOWN and trace up onto the leg of it with a little glob of paste to blue down the component and electrically attach it to your trace. no soldering needed AT ALL.
