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 RU-vid 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!
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
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.
This is NOT the “SemiConductor channel”…if you want Semiconductor specific info go to the Semiconductor channel! this is PCB (Printed Circuit Board) Channel !!!
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?
@@lewiskelly14 So what!. What's YOUR effort. A train trouble ad, who cares. Take a look at yourself! Make a Real effort! your 11 subscribers - justified.
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 :)
The gold can perhaps be replaced into recycled aluminium in combination with recycled glass and plastic. Just a remark Thank you for this video, kind regards.
Good video, albeit laminated PCB's aren't used for Ultra/HDI packaging applications like Apple Air Pods, which use thin-film ABF low temp build up process.
Good work. Please higher the pace of releasing quality videos, hire teams of people, better production value would be very appriciated. Dont want to spend my whole life learning these concepts :D You are trully making difference in peoples lifes, Keep it up and hopefully beyond.
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.
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.
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!
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…
@@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! :)
sir can we simulate and see the actual working condition of the circuit diagram when we use easy eda software , plz give us a link to down load it , teach us how to use it how to simulate a drawn circuit diagram
Blessings in an abundance of the faith. I salute you. 😘🙏Grace and peace be unto you and to this place. God bless you. Thank you. Will you believe and receive Jesus Christ as your LORD and personal saviour??? I do. 😊
Anyone here first to comment after watching the while video? 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. This is just a promotional clip amalgamation of jcpclb or whatever and easyeda. This video should be on their channels.
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.
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 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 dielectric breakdown happens only when there is over current, while electromagnetic induction happens at any current with varying intensity of course
