Hello everyone, we hope you enjoyed the PCB video. Now, get 1-8 layer PCBs at $2 and also get a $54 JLCPCB new user coupon from jlcpcb.com/RHS

No. Basically a sponsored video. Piss off.

Can you please make a detailed video on how semiconductors are practically manufactured by doping silicon crystals with Boron, Phosphorus and other substances? Because that's the basics behind the manufacturing of all modern electronics. No one on KZbin shows how silicon crystals are practically converted to N-type or P-type semiconductors and other stuff like that. I enjoy watching your channel and learning since 4-5 years and I must say, you guys are the best!

[@RyanDiederich]

they use this exact same process, just at a nano scale. They use basically atomized atomic sources to "spray" atoms onto a substrate, and there are ways to mask. Most of the effort and work is building copper structures, the creating of transistors as you describe is only at the cores of the chips or storage arrays, in which case there are many ways to etch the little machines out of the surface

[@anonymous.youtuber]

If one have access to a research nuclear reactor, the thermal neutrons it produces can be used to irradiate a Si ingot. Part of the Si consists of the isotope Si-30, which becomes Si-31, which in turn becomes P-31 by emitting an electron. This minute amount of phosphorus changes the silicon into n- type silicon.

Please don't fool us again with these long form advertisements. This was such a step down from the quality of your normal videos. This explanation of the PCB production process was rushed and poorly explained. The video should have been twice as long and way more detailed. This was just a marketing gimmick for some shady PCB company that provided videos' to Lesics that didn't explain anything. I am staying far away from JLCPBP after this video.

Can you make a video on glass used in making lenses? How are optics grade glass cut to make the appropriate light diffraction? How are incorrectly cut lenses cut to correct any imperfections?

Boy, those airpods are a true marvel of technology. 63v rated electrolytics in such a tiny package xD

where's the 63 volts?

[@staviq]

It's a joke, they used random PCB 3d model in the video, not an actual airpod PCB, and when the video zooms in on it, you can see THT electrolytic capacitors with 63V rating on them, which in reality are bigger than the entire airpod itself, making it quite hilarious :)

[@JessiOz2k07]

This channel is great but they either complicate or simplify topic at hand by either adding too much necessary information or skipping over a lot of important info. Plus they name their videos that seem to promise a lot more than what the videos actually deliver.

[@37prakhar]

So, we can come to see the video only for an overview. The technology behind it goes beyond high above our head.

[@laurisikio]

I think learn engineering used to make very good educational videos. Nowadays the videos are filled with merchandise, business partners and hidden trademarks (MacBook in this video as an example). Moreover, lesics seems to be a bit biased even when it comes to inventions: some technologies they consider obsolete and some things they adore.

[@Tarex_]

Well..guess im gonna need a load of nitric acid on order now

[@THEELECTRICGUY]

Ok. So here are few points you need to improve on: 1. 2:33 We don't use a 2 layer PCB just to reduce PCB size. A 2 layer PCB can have separate ground plane so that we don't have to route ground nets. Also it provide shortest return path and hence reducing EMI and improves signal integrity. Also, usually we don't add components on the 2nd layer of a 2 layer PCB! 2. 3:34 No explanation was provided for how adding ground plane reduces EMI. Pls refer Eric Bogatin and Robert Fernance videos for this! 3. 4:07 Those are stitching vias. Used to stitch two ground or power planes. 4. Instead of adding more related information, u want to extract gold from PCB! Why? Maybe you could have explained about the complete manufacturing cycle (Design, Prototyping, Manufacturing, PCB test gig, EMC compliance process, etc. I hope you will improve on this! Thank you!

[@BoomBustProfits]

What a narrow, selfish view…Did it ever occur to you that you are not they are not making these videos just for you? You the only one watching it…not everyone wants detailed info tangentially related stuff…

[@THEELECTRICGUY]

@@BoomBustProfits I see a partiality here! These guys explains the mechanical related stuff in depth but touches only the surface when it comes to the electronics part. Maybe I am selfish or maybe I just expect more from them! :)

Ya khali ye hi race jeetni hai sabji 😂 Also, disappointed to see such cookie cutter video from great channel who used to make quality content.

Any promotional material should be marked as ads separately and not masked like this. I am sure there are other alternatives to these softwares. Promotion code in comments added sneakily without any mention in the video.

[@bellzon4086]

2:59 You meant electric field?

[@pitrek121g]

No, he meant magnetic field. Electricity and magnetism are very closely tied. The higher the current the stronger the field. If you put a compass near a cable with a current it will impact the comapss' needle. Magnetism can also produce the electricity, that's what call the electric induction. That is also why Sun can destroy all electric devices on Earth with strong magnetic winds.

[@bellzon4086]

@@pitrek121g I see ty for explaining. But isn't there also electric field between wires?

[@pitrek121g]

@@bellzon4086 of course there is but electric field is more particles related. He said magnetic field because it is the one that is "making problems" in circuts, not the electric one.

[@bellzon4086]

[@organicfarm5524]

@@bellzon4086 dielectric breakdown happens only when there is over current, while electromagnetic induction happens at any current with varying intensity of course
