As per previous commentator, these are boards made for low-end products, such as appliances, tools, home widgets, and similar. These are not the plants for Iphones or similar. Those factories require much higher caliber equipment. This is basically a plant modeled after 1970s-to-1990s USA equipment, but with better production handling. We used to do this, but was much slower.
Cool video, similar to equipment I encountered 30 years ago but much larger scale. One thing that isn't clear is how they handle plated-through holes, and "buried vias" between layers. The plating process section of the video was a bit disappointing for that reason. The testing robots were fun to watch!
A curious blend of highly automated sections mixed with janky-looking manual handling in durty industrial environments. Also, way more production steps than I personally expected - I clearly need to give the humble PCB (and the people that make them!) a lot more credit from now on. :D

this documentary is for people who knows the process of making pcb. many years ago I worked in company making single layer PCB. during those times multi layer PCB don't exist.
In the late 70's I was working for Ferranti (UK computer company) and the boards then were 16 layer. I was writing ECN's for field fixes, some the instructions involved getting down to sub board layers and cutting tracks by hand, of course component density was much less, but even so it seems like madness now looking back
@@cbartley100 Big-iron mainframes and supercomputers back in the day could have some serious PCBs, but of course those were highly specialized and horrifically expensive. My 1980s humble 16/32-bit home computer had a two-layer mainboard, and all the components were solder-through, no surface mounting at all...
A ton of critical information is cut-out from the video. Like, how do you align all layers? Why do you apply solder mask to the entire surface and how do you remove it from pads later? How did you do vias and their inner plating?
@@PSRao_1712 The problem is not "not being able to show everything". They precisely cut out the "commercial secret" stuff. And that makes this video a little bit of click bait.
You can sort a coat the pads, so the mask wont stick to it and get washed off later. Vias and inner plating is pretty easy. You aplly the via, the thickening is done in a galvanic copper bath.
Aligning is done just like with printing on paper (different colors applied in different steps), by adding certain patterns (like crosses + inverse) that have to match (adjusted by humans or image recognition), sometimes visible around the mounting holes. Vias - interesting question. At 8:45 it is mentioned, that "holes are metallized for generating conducting paths" (I think, visible at 9:29), which works for adjacent layers. For connecting distant layers, I guess, it'll be either rivets or holes, that get soldered through, later on. On many boards you can see such sub-mm holes.
Solder mask is not applied to the entire surface. It's transferred via a silk screen, so only the required areas are painted. Much like offset printing.
oh !!! my god how meany time posse & veryus machinery work & manpower time use very nice this video maker & this project director & staff good works this PCB Manufacturing Insight i selud this work i have print on screen printing pc in mfg unit my city Navsari, Gujarat, India,
The multi-layer stuff happens between 04:00 until around 06:22 where they put prepreg and finally the outer copper layer under and over the preciously etched inner core. The whole stack ins being put into the oven/press to be glued together. After that drilling for through-holes and vias. Masking and etching, then further copper deposit to bring the outer copper layer to thickness, and at the same time plate the vias
@@PSRao_1712 Nothing at all shown about how the multiple layers are interconnected nothing on thru plating the bits shown are common knowldge the REAL interesting parts were left out
forget about how automated this process is, I am so amazed how many people are involved in the design of the circuit board making machine: R&D, electronics, schematics, mechanisms and number of days it took technicians to get this machine going. Well notwithstanding the advancement in technology why China is using junk parts to make product fail so fast and obsolescence is eminent. It is outright deceptions. What a shame.

You can freely add more power to the processors, video card and chipset. Enable the performance mode for everyone around the world. You can disable the overheating, fan overspeed because an old law took effect, that doesn’t require the heat monitoring. The law is cruel, and since 2 years it works: make sure homotics, that’s covid thank you. Helicopter and fighter jet pilots make their own decision, the pcb is excluded from the decision making. That is because the automatic decisions can easily be tricked, when they came to effect, they were already programmed to be misleading.
I thought so at first, but then I realised I can pay attention to what's going on, without the distraction of a narrator. It's useful, but only if you've already read about the process or saw the quick explanation videos.
What is surprising is the considerable amount of manual handling required in the whole process!

Does anyone know if the prepreg in standard FR4 boards can be used as a dielectric layer in metal PCBs?
The answer is yes. With out copper the board is called G10.
PCB manufacturing is not a high-tech technology, but in China, PCB intelligence can reduce the cost to the lowest level.
👍👍👍👍👍🔥🔥🔥🔥100 %
WoW😱
From the video I understood only what I know - how single side or double sided PCBs are made. I didn't understand how multilayer PCBs are made
Made inside and stack outside
Each PCB is patterned & joined using prepreg, as shown. Alignment is important.
they joined many layers of circuit using vacuum and temperature so that only components mounted on top and bottom. circuits are hidden in the layers.
The multi-layer stuff happens between 04:00 until around 06:22 where they put prepreg and finally the outer copper layer under and over the preciously etched inner core. The whole stack ins being put into the oven/press to be glued together. After that drilling for through-holes and vias.

Have soldered on on them for years but never seen how they were made.
So they don't test the boards for connectivity before they ship them?
They showed both electrical and optical inspection in the video
Hope you all did get how it's done, cause I'm on my way of doing it now that I know.
I love how the material goes from being treated like a baby from people in fully covered lab suits to a dirty man throwing it around.
you need the designs first for each layer.. this is a lengthy process for both design and production

how many layers is possible.. 50 layers on a motherboard? thats so compact
You are only limited to dielectric strength and stabilty of the whole board.
