You asked how printed circuit boards are made. I did the homework.

[@3nertia]

Hell yes I'd like to see pcb manufacturing - that's what I thought I was clicking this video for! There are already several videos on how pick-and-place robots and reflow ovens work :/

[@tomazzaman]

I gotchu.

[@ZoeyR86]

I have a full line in my garage. I have a solder paste printer > 3x neoden 9 pnp machines into a stacker and an auto feeder to my neoden IN12C reflow oven.. I can do small scale production runs. As long no sides have more than 140-170 unique parts (depends on size of parts) i can run my line at full speed around 12,000 cph. An example i did recently was a board for a custom poe camera the bom has 434 parts but only 107 unique with most parts being 201 / 402 resistors and caps this entire board used 2 trays 1 14mm reel and the rest was all 8mm reels it's possible to run this entirely on one pnp machine but by moving the bigger parts to the 2nd machine i can drop the speeds and get better accuracy. So generally machine 1 is smallest parts general things like resistors, caps, inductors and maybe sot-23. Basically 8mm reels only. Machine 3 is big stuff like MCU's CPU's BGA's and tray parts. Machine 2 fills in the middle some parts will get moved between machine 1 and 2 so the op times balance out so no 1 machines waits on another. I have about 100k invested in my shop my net cash flow is 4x that 😂. So it has paid itself off in under a year BUT I'm a hardware engineer most the board i build are designed by me under contract.

[@meco]

please make a video about that setup

[@tomazzaman]

Oh wow, that's pretty amazing!

[@pahnazd]

I remember learning to make PCBs by hand in high school. Glad this process is a smidge more sophisticated and matured.

[@pineapplerindm]

I think title should be "I _did_ the homework"

[@tomazzaman]

Fixed, thank you!

[@StephenBeaudet]

Very cool! Any more behind-the-scenes stuff you can share, please do. Technology is amazing and there's so much to learn. Thanks for another excellent video!

[@tomazzaman]

You're welcome! Plenty more to come! :)

[@alec1575]

Sweet, I like the inside view of the production of the boards.

[@urbanbevc6498]

Very nice presentation! When algorithm showed me your video about BOM for router project, I watched all of your videos in one go. What an exiting journey you took, it’s amazing content you make Sodržavljan, ing elektronike in dizajner PCB, srečno, gotovo se kje srečamo 😀

[@tomazzaman]

Hvala! :)

[@marekvojta9648]

I would call this part as third part (placing things onto PCB) second would be making of PCB mqking blank PCB from sheet) and finally the first projecting a PCB in first. Yes I know I'm annoying🙂. By the way I would like to see the second/first part (blank PCB making or even the projecting) if you went to see this process.

[@ILike2Tinker]

I would love to see the process of how the board is made prior to this point.

[@tomazzaman]

Deal! Will make the calls!

[@winsucker7755]

So that's how babies are made! PCB manufacturing must be hard, since my mother and father, and a neighbour were fighting so much in a bedroom!

[@uros8lilek]

AAA so that's how they are made!

[@OhItIsTom]

hey new subscriber here! love the content ive seen just wondered how you fund all these personal projects and what you do / did for a living if thats not too personal! your videos pretty much fit into every niche i enjoy myself it's quite shocking, was interested in how you have so much success in so many areas!

[@tomazzaman]

I'm the founder of Codeable (codeable.io). Thankfully, the company has been successful with customers from all over the world. I'm not part of it anymore - I left in 2022, but it's the insanely stressful first five years of that company that's now paying dividends, you could say :)

[@OhItIsTom]

@@tomazzaman that's super cool!

[@juebaitube]

Very interesting. Thanks.

[@tomazzaman]

You're welcome!

[@thestormpooper697]

yes

[@Kabodanki]

Nice at least it’s not the chinese pcb manufacturers. I would prefer to give money to people closest to where I live. Shout out to you

As feedback, I suggest you slow down a little bit your dictation. I think I would be better for your audience, especially those who don't have English as their first language.

[@tomazzaman]

Thanks for the feedback!

[@OhItIsTom]

I kindly disagree, subtitles exist

[@marcioslsouza]

@@OhItIsTom@OhItIsTom I know that, but as I said, I was giving feedback. I usually use subtitles, but that was not my point. Some people are not prone to use subtitles.

[@OhItIsTom]

@@marcioslsouza as a native English speaker his pacing seems fine but it's subjective I guess

[@marcioslsouza]

@@OhItIsTom Yeap, I agree with you!
