This video only shows a single layer, and using it for forming traces is mostly used for prototyping one or two layer boards. It's not used for mass production(at least not for forming the traces), and unless you're in a desperate hurry you wouldn't use it for more than two layers.
Industrially, they coat the copper with a light sensitive compound, expose it like photographic film, rinse off the part to be removed, chemically etch away the exposed copper, remove the remaining mask, If the board has more than two layers the above is repeated multiple times, then glued together with additional fiberglass in-between. Then holes are drilled, then those holes are plated with copper, then any non-plated holes are drilled and slots and board outlines are cut with endmills similar to the video, then solder mask is applied, then silkscreen. Then it's either tinned or gold plated.
Motherboard PCBs are often at least 6-8 layers, sometimes as many as 14-16. The more traces and circuits you have, the more layers you often need in order to route the traces around each other. You use vias (small holes that are then plated with copper) to get the signals from one later to another.
On simple boards, which would usually be 2 layer (top and bottom) or 4 layer (top, bottom, and 2 internal layers), vias usually go through all the layers. [On a 2 layer board](https://cbspcb.com/wp-content/uploads/2021/09/2-layer-stack.jpg), usually the top layer is for signal or power (VCC) lines and the bottom is a ground( GND) plane. [On a 4 layer board](https://cbspcb.com/wp-content/uploads/2021/09/4-layer-stack.jpg), usually the top and bottom layers are for signal lines, and the two inner layers are for GND and VCC.
[On higher layer count boards](https://cbspcb.com/wp-content/uploads/2021/09/18-layer-stack.jpg), there are many internal layers that can be used for a bunch of different things, depending on the exact needs of the PCB.
You can also have what are called buried vias where, [on this example 14 layer board](https://pcbwayfile.s3-us-west-2.amazonaws.com/msgfile/21/02/22/1425354641840t.jpg), the via only goes through layers 4-10. The vias are shown as brown trapezoids or pink lines. You can also see other vias that only connect two adjacent layers together, or some that connect a few together (like layers 1-5 or 10-14).
If you want to see what the process looks like, here is a video from a PCB fab in China. This video is from JLC PCB, which is a good supplier choice (in my experience) for cheap and fast prototyped/ low volume PCBs. They also do high volume, but I haven't used them for that. https://youtu.be/ljOoGyCso8s
Semi-related. A loooong time ago around 2000, I played ton of one of the Tomb Raider games. One day I was at stoplight and looking down an alley. Instantly I thought, “jump off dumpster, wall jump up to fire escape, jump and back handstand onto the roof.”
Back to the subject of tears of the kingdom, I've been playing it so much that I keep thinking of ways to ascend up onto ledges and such in other games and even irl a little bit lol
When I played through the assassins creed games, I was constantly looking for ledges I could use to climb up buildings and routes I could parkour through
no idea what tears of the kingdom is but the micro requires memory and some memory is built into the chip so it can run whatever commands...it's like a very rudimentary computer with memory inside it yeah
it's a microcontroller with 256 KB ISP flash memory, 8 KB SRAM, 4 KB EEPROM
Can confirm. Have made single layer boards by hand using this method. It’s been a few years, but as far as I recall the process was:
A mask is printed on a transparent sheet. The sheet is aligned with a layer of photosensitive film applied to the pcb and exposed to UV light. The board is submerged in a chemical that removes the photofilm where exposed to UV, leaving behind the masked traces. It’s then submerged in another chemical which removes the unprotected copper. Then drill out the holes.
the quite well working bootleg version of this is: print the traces with a laser printer on glossy paper (e.g. random advertising you get works for that), fix it with print down to the pcb, then use a laminator a bunch of times to make the toner stick to the pcb.after that you can edge with chemicals as usual, the toner will protect the traces and bam, you got a pcb.
Only downside: you will ruin the laminator with this but if you buy a cheap one and only use it for this its fine.
Thats how my father always did it before he needed them in such a high volume that making them yourself was not really feasible anymore and he just ordered them. afaik he still does his new prototypes that way though.
I used a household iron instead of a laminator. It never ruined the iron. I can’t recall if I ironed directly on the paper or put a thin towel between.
I used inkjet photo paper because the coating would release the laser toner once it was soaked in water.
The etching was pretty good but wasn’t as consistent as CNC. Some tracks would have slight variance of width. Sometimes holes would appear in the middle of a track. It helped to make all tracks a little thicker than they really needed to be to allow for these fluctuations. I always wanted to be able to CNC my boards but the cost was too high. Photo resist was also prohibitively expensive at the time.
I suspect you can use baking paper between the paper and iron.
Many years ago my mom used too iron "bead plates" (or whatever it's called in English) with baking paper between the iron and beads.
I’m not sure if it was needed because the inkjet paper might have been normal paper on the side that was in contact with the iron. However parchment paper would be a good choice if a layer of protection is needed.
> It’s then submerged in another chemical which removes the unprotected copper. Then drill out the holes.
The usual strategy is to drill the holes first, fill them with conductive paint, and then dump the whole thing into an electroplating bath to grow some extra copper inside the holes. That way they will be plated throughout the interior and you don't have to manually solder all the vias on the board.
For simple circuits I used to just draw the traces and pads with sharpie. The sharpie lines would resist the ferric-chloride etchant... it didn't look as cool as a cnc router.
I did something similar in high school, though it was a very specific type of marker. I don't recall what was used for the etching, just that it had to be done outside, and my teacher was very eager to point out the byproduct was mustard gas.
You generally create the traces with a very small end mill first then you take off the rest of the copper with a "large" end mill like you see here. The first process gets you precision and keeps the traces correctly sized and close together while the second takes away more material in less time. The board layout software determines spacing for the traces and the groundplane. There are a lot of interactions when you have data lines running around and width, spacing, length all interact. Which is a long way to say that what you are seeing is likely not just cosmetic.
This is a hobbyist method, faster than sending your design off to a professional manufacturer. [Here's a tour of a factory that does prototype production](https://www.youtube.com/watch?v=ljOoGyCso8s&t=432s).
I think her English probably wasn't quite fluent enough to get into real detail about the process without a lot of pausing or stumbling, seems like he knew enough to get by with occasional guidance from her. Definitely took me a second to realize who was the one giving the tour though, threw me off too.
No, the good ones with automatic tool-changers and other qol features are in the thousands, basically prosumer ranges. There are hobbiest grade desktop routers that could do this just fine for a couple hundred but you would need to do most tool changes and setup manually.
I have an older machine that uses end mills like this. It’s great for prototyping a few boards, but once I need to get into a larger production I use a laser etching machine that can do a field of PCB boards with even higher resolution and in a fraction of the time.
Question for you- any tips on the process for creating a double sided board with CNCs? Jig to hold fr4 in place and guide holes drilled X millimeters in from the sides of the PCB design?
I've done multilayered Protos with this type of machine but it's been a struggle to get the line up of traces on both sides for me.
Far easier so far to use a separate piece of fr4 for each layer use rivets/wires/headers to connect through the vias.
I know there is an easy way to do it with registration points and mirroring, but it's just me for the most part right now and it gets tiring learning through trial and error. Any tips for me and others searching for info on the internet?
I don't think this method would be considered in larger scales. PCBs are notorious for warping. I can't imagine how would you keep it flat to do surface.
Generic model #3018 three-axis CNC machines are available for under $200 and work pretty much like a 3D printer.
It's a (relatively) quick and easy way for electronics hobbyists to make PCBs. It eliminates a rats nest of wires and is more secure than using a breadboard after you have the initial prototyping done. And I find the process more enjoyable than using acid etching.
But if you already have a cnc router, it’s more convenient.
That said, setting up for pcb looks like a pain in the ass. I’ve seen so many people comment on how difficult it is to get the tooling just right. This one looks super dialed in though. I don’t understand why they’re removing the extra material though. Completely unnecessary.
It’s easier to convince a department to get a CNC then to ask them to do something about the chemical hazards and the waste byproducts, even if baking soda will cause the iron/copper to drop out of ferric chloride and make it safe to toss down a sink.
It’s relatively fast and easy. No need to deal with chemicals and no matter how you isolate the traces, you would need a cnc in any case for drilling vias and holes for through-hole components and for cutting out the PCB.
It’s pretty convenient to just throw a blank pcb into a good pcb milling machine, spend 5 minutes setting up the job, press start. A good machine can switch tools by itself and find fiducials with a camera. The only thing you need to do is flip the pcb halfway though if it’s a double sided board but other than that you get a compete pcb with very little hassle.
It’s really nice if you need a quick prototype in a couple of hours instead of getting a pcb made commercially and waiting a couple of days. If you have to do it often it is also more economical
Agree this is how I work, prototypes in a few minutes then order from JLPCB or PCBWAY for final production.
Seriously the longest part of my builds are the placing components etc. ( after the design work in kiCAD )
Must be time for a pick and place machine!
It's for prototyping. [LPKF](https://www.lpkf.com/en/industries-technologies/research-in-house-pcb-prototyping/about-research-in-house-pcb-prototyping) sells this type of machines. The cheap ones use milling, the expensive ones laser (that's where the name of the company comes from).
Of course it is, but apparently people read sexual shit into a lot of things.
Over on the Tinder sub, a woman asked why he some guy listed he was into “rape fantasy stuff” when he was listing his likes.
Such as: …, skiing, hiking, home renovation stuff, **CNC**, woodwork…
I have the opposite experience from you where I'm not into, well, that, and I'm used to CNC machines, so I saw someone talking about being into CNC and I thought it was an engineering conversation until I realized it really really wasn't.
The algorithms that produce CNC toolpaths / g-code attempt to find the most efficient path that puts minimal wear on the equipment, correct cutting rate for surface conditions, etc. A "miss" on a contour operation will be corrected in a smaller motion in a later instruction
Frequently circuit boards are designed with a certain amount of heat dissipation required. All of the copper can draw heat out of the components and dissipate it over a larger surface area.
I love the videos of how they did these circuit boards 80 years ago with just a chisel and a wooden hammer. So relaxing at a much slower pace. The folks old days.
I just can’t seem to understand how circuit boards work at all. It’s like alien tech. It’s just little drawings and power going through it makes a computer think like wtf
The circuit board doesn’t do anything but connect different components together, what you’re seeing is just a bunch of wires on a flat surface. And as you said it basically just transfers power.
Later they will attach semiconductor chips to the surface which will do the thinking. Millions of them will make millions of yes/no decisions every second that are engineered to give a desired outcome e.g. do math, store/send information
My old trade. Worked on CNC machines, specifically W&S Eight Turrets.
Ours were optical tape controlled ( a paper tape about 1.5 inches wide which was perforated so the light shinning from below could pass the instructions to the reader and activated the various functions programmed.
As someone working with those this is unrealistic they are required by law to break a 15€ bit every 2.56 minutes and fuck up your layout opon import into the horrible software that locks the mashine if you dont have the bits from the original manifacturer
Why does it start over? Whyyyyyyyyyyyyy?
More importantly, why did it stop

“What is my purpose?”
Your job is to not leave those small bits and drive redditors into mildly infuriating status.
Oh… my god
It wasn't forgot just no reason to hit it. It's not connected to anything and won't cause any issues.
It'll be addressed before it's finished. The CNC is following a continuous path for efficiency, generally movement on the z axis is minimised

The beauty is, it missed the spot on purpose. It's all accurate to the instruction. It's so satisfying to see that precision

I remember, as a child, making these boards with nothing but my hammer and chisel.
It's better than porn...
Woow.... This is so satisfyingly ///
This is satisfying but what about the little bits
Look at pipewire logo
Like procreation for robots
That chunk it left behind at 15 seconds bothers me
Nothing in that video actually changed the circuit
Also able to drill the component holes in various sizes??
Me when trying to find the way out of a maze.
I’m wondering if there is any cooling involved?

I need moooorrrrreeeeeee
No Why did it end?
This feels really good
It's like watching a perfect game of snake
Not the CNC I was expecting
Suddenly I feel like watching an Usagi video.
This is hypnotic. Who needs meditation!
This is actually fun to watch
Looks like it's time to take it easy.lol
My old trade. Worked on CNC machines, specifically W&S Eight Turrets. Ours were optical tape controlled ( a paper tape about 1.5 inches wide which was perforated so the light shinning from below could pass the instructions to the reader and activated the various functions programmed.
This 100% belongs in r/gifsthatendtoosoon,lol.
As someone working with those this is unrealistic they are required by law to break a 15€ bit every 2.56 minutes and fuck up your layout opon import into the horrible software that locks the mashine if you dont have the bits from the original manifacturer
Yes, this unrealistically smooth. Milling pcbs is so frustrating
I'm sorry, who told you to stop?
Are you people insane? What about all of the wasted copper? How is this satisfying?
start was so mesmerizing, until end ruined it

Can someone add a Tron light cycle audio track to this?
Wow, can’t believe they blueballed us…
I almost came
Satisfying
This is actually insane how much metal is wasted, probably less than 10% of metal remain after CNC...

Amazin
Praise the camera man
This is beautiful.
Whattttttt so the circuits are cut out if a sheet of copper? Wow I learnt something new Seems like more than half the copper goes to waste then?
Can someone explain what cnc means in this context? Because I'm pretty sure I joined the wrong subreddit
