As someone who works in a professional manufacturing environment with sintered silver inks, surface prep is hugely important to get good bonding to the substrate. Sanding the substrate at ~200 grit then cleaning with isopropyl before printing should help a lot. There is also some benefit to doing a 2-step sinter process where you bake once as normal then do a second bake under mechanical pressure (clamp PCB between 2 pieces of jig plate metal or borosilicate glass)

Ah yes, back in the 80"s. Back then there existed PAY TV. Of course every engineer and technician where I worked wanted to create their own pay TV converter. I, as a technician, was self educated, and thus my approach was different. The pay TV system worked by raising the horizontal sync pulse up into the video area such that the TV could not detect it, and thus this picture was scrambled. However, the horizontal sync pulse was not touched during the vertical sync pulse. So I made a simple circuit that would check to see if the next horizontal sync pulse was in the right position or not, if not, it would make the correction. So It became a line by line correction system. Total cost for a single home made PCB and its components. was about $6.00. It required only 15 mA current at 12 Vdc. So you simply placed it within a TV converter that had volume control. Meanwhile, the engineers used the PLL method to fix the sync problem. This required lots of components and thus a complete power supply and a box to put it all within. My boss tried to then sell my design to the cable company, but they turned it down due to my design being so simple and easy to copy. Oh, and my design gave a 6 dB signal to noise ratio better performance than did the cable company decoder. They had shifted the horizontal sync pulse by dropping the RF signal strength during the horizontal pulse, by 6 dB, and then dropping the RF signal during the video section strength by 6dB at the decoder to match up again with the 6dB suppressed horizontal sync pulse. Of course my method did no RF suppressing at all, and thus the picture quality was better. . Ah, the good old days.

You could make the whole back of the PCB a ground and use thru-hole capacitors as bypass with one leg formed to work on a SMD pad. The idea is that the ground leg of the capacitor jumps the connection to the top of the PCB. This way there is no alignment needed. You just have to handsolder the capacitors after the reflow is done. You will need the super low temperature solder for that. Also: If you use a zero Ohm 1206 resistor you can run a wire under it to get your layout to work.

Interesting machine but the finished boards seem like the traces would be very fragile. I'm surprised we don't have a group of "do it yourself" guys developing a print head that could be adapted to a normal 3D printer. We would still be at the mercy of the ink manufacturer for ink prices. If they come up with a powdered iron mixture they could print some interesting transformer cores and electric motor hubs. These could also then be magnetized for motors, generators and guitar pickups for example. With a two headed printer such as a modified 3D printer we could use one head to lay down a layer of iron core for a transformer and then print the winding layer with the trace head. Cure it with a built in heater head and then print the next layer. Keep going to print complete motors for example.

@@atomic14 I disagree. Moving this technology over to the common 3D printer platform would bring the cost way down and open up many avenues of development. Currently printed circuit boards are flat. One this technology is blended with common 3D printers we will be able to print circuit boards of any shape. The printer could have an additional head that prints out a slurry of plastic powder with UV cured glue which could then be hardened with a UV diode or UV diode laser. A slurry of powdered glass and UV hardening resin is another possibility. On top of these layers we could print the conductive traces to be used like wires. Those old fashioned ball ended variable tuners for early radio could easily be printed out without the need to make the hub and then wind it with wire. Getting away from flat circuit boards; circuits would fit into watches that curve around your wrist better. Choke coils could be drawn and printed in addition to circuit boards. The disk iron core could be printed in layers with an iron powder with UV hardening epoxy. The coil around this core would be printed in separate layers using the silver compounds or copper versions. The current slicer software for 3D printers could easily be adapted to these concepts.

I'm still skeptical of these things, the ink is just too sloppy for anything tighter than what's shown here, and baking seemingly adds to that, plus fully exposed traces, and the soldering situation. For home kit stuff, I think using an MSLA printer works better on PCB blanks, you get a digital mask and UV lights in one step. Not to mention the cost differential, especially when this process has consumables that're (last time I looked) proprietary to the company itself. This machine just does not make sense anywhere, other than being a rapid prototyper for a large company, yet there's also better prototyping alternatives.

IMO, they really missed out on adding an attachment for a fine tipped paint marker to do silkscreen markings - it shouldn't be difficult to do considering it's the same process as their conductive ink prints except it's a different ink or using just a mechanical jig to hold a marker. They could probably even provide a dispenser to do UV cured solder mask (not necessarily for their printed boards) since the software already has a 'homing' function so in theory an etched board with the appropriate gerber files would allow for this. The price of the machine though... Way too steep for a hobbyist especially for those in regions where etchants are readily available (unfortunately not for me). I can see how this might be useful for a small business specializing in producing prototypes just purely as a solder paste dispenser since they'd not need to make/ procure stencils.

Interesting that the actual x-y movement is quite quick while printing, but the z movement is quite slow and there's a pause at the end of each movement before a positive z movement. I assume the pause is to reduce the sizes of holes and bumps in the printed ink. I wonder if the software has tuning for the z speed. It also looks like there could be some pretty significant efficiency optimisations that could be done, such as printing complete nets in one go rather than doing several segments and pads separately. I'm guessing that, with the way the solder doesn't wet the pads quite the same way as traditional copper pads does, solder resist isn't as important, but I don't see why they couldn't have you swap out a tube of lacquer to give you that option. Same for a "silk screen" layer which could just be a pen attachment. Aligning a double-sided board probably wouldn't be too hard if you also had the drill attachment since you'd just need to provide two or three drill sites similar to the alignment process done for the solder paste step. Also, though I see the official video shows them inserting the via and through-hole rivets after printing, I think it'd probably be easier to do it before printing the traces and pads. It would certainly be cool if this technology could be integrated into a pick-n-place machine for an all-in-one process where you'd stick a blank sheet of fibreglass and get a completed circuit board at the end (that'd probably have to only be single-sided, though unless you _really_ complicated matters by adding the ability for it to flip the board itself).

I'm wondering if using an abrasive on the board before you print the traces and pads on the board would make them adhere better. The surface of that board looks a lot like you're printing on glass, which would have very little binding strength.

i had problems when i had an led on pin 2 or 4 (in not sure wich didnt work). when i wantet to upload an arduino programm in my esp32 dev board, the esp worked fine to upload on my laptop but on pc i always needet to press the boot button, but this didnt work... so the programming always timed out. it took me a while to find the problem, because i made 2 of the same boards but i used my pcb cnc. one for my friend, and one for me. my one did work without any problem,but the other board did not work and looked like it was write protected... all parts where the same only the ir recivers did came from old pcbs i salvaged. but the problem was that i had the resistors for the leds a little too small, and the tolerance in the resistors itselve did cause the problem. just used ones with higher resistance and it worked just fine.

With the USB port issue, couldn't you drill through the board and secure the connector to the PCB with some jumper wire or something, so there's no force exterted on the bond when inserting/removing the cable? While lining up a double-sided print would be difficult, doing some selective drilling to secure things like headers, switches etc would be easy enough?
@kensmith56948 ай бұрын
How about mount the connector on the back of the PCB. The pins can go through holes to traces on the top surface. This would be a lost stronger than an SMD connector.

Cool in concept, nice to watch on youtube - but in practice its a non starter - too limited, too expensive. Isolation milling can be had for 250eu with 3018, for 5k you can probably get a LPKF machine that will outdo this one by a mile and half.

If this can be used a CNC milling machine, whats the point of the silver paint? You can probably make better PCBs using the milling function.

The main issue with the machine would be how strong the milling head is attached to the machine. Currently everything is attached by strong magnets so you can't apply too much lateral force to the head.

Little question from a mechanic : why do you put soldering past on all esp32 points even the one that not used ? Doesn't it increase the risk of short cut without bringing any advantage ?
@ABaumstumpf9 ай бұрын
Thermals and mechanics: The pins are the only thing holding the chip to the board and a major path for heat to leave the silicon. SMD parts can have fairly substantial current-ratings cause they can have a direct metal-to-metal connection for cooling (given a big enough copper infill).

Interesting tech. The problem is just a little more complexity and you’ll need a via. What’s the solution then? I don’t see this as being any more useful then toner transfer and good old FC. I’m not even sure it can make finer traces.
@atomic149 ай бұрын
Definitely, and once you start drilling holes, aligning top and bottom prints, and then banging in tiny rivets... it feels good for quick simple prototypes where breadboard is too messy, but is it in a sweet spot where it's really useful.
@BRUXXUS9 ай бұрын
So expensive 😢. It’s a glorified 3D printer, so it’s a little wild we haven’t seen some cheaper alternatives. Or… maybe there are some? The movement system isn’t that much different, and precision seems like it’s even less important since the ink and paste squish out some. 🤔. I guess when using the drill it would need more rigidity and precision.
@newolde19 ай бұрын
I think you're right. Considering it's a glorified dremel doing plunge cuts, not routing it doesn't seem like you'd need a stronger structure. Decent sized linear rails vs the standard roller design on low grade printers might be helpful to minimize torsion. I'd almost bet someone out there has already done this somewhere. That said the laser engraver method which was outlined on this channel or the resin printer solution seems like just as viable of a solution with much less tinkering involved.
@jfieqj9 ай бұрын
That's a lot of limitations for the price, but it's also pretty cool that it does the solder paste all in one. Had a thought on a really strong way to mount modules like that USB board. Instead of soldering on a pin header first, I would take the headers out of the module, and try soldering the bottom of those vias onto pads on the board, BGA style. Then for strength you could screw the module directly onto the board using the holes in the module and some corresponding holes on your PCB. I think that would hold up to quite a lot of abuse.

I've never tried milling, but I imagine that's the copper to board bond is much stronger. Also copper will have much lower resistance. I think this is a good for very quick prototypes - I'll see over the next few months how much use I get from it.

@BlondieSL9 ай бұрын
@@atomic14 Another option that should be easy, would be to use sockets that have mounting holes where you can drill through the PCB and put small screws to hold it. Another option, would be those sockets with little legs that go through the board to be soldered. With those, you could drill the pass-through holes after the trace is laid and where possible, add a bit of the ink, by hand, to the underside. Then you can mount the socket, legs through the PCB and solder both sides. That "should" hold much better.
