BTW, for everyone who doesn't know (I didn't know), JLCPCB, LCSC, EasyEDA, they are all the same company (JLC Group) and it also includes a company called ZXHPCB (large-batch PCB fabrication)
This channel Rocks, all the things I ever imagined. Now I understand where the datasheets span from
I am always amazed that they use only one LCD screen for this type of work.
Such tiny desk configuration for a whole day on PC.
Kind of frugality lesson.
Wow this is really cool, and helps me gain confidence using these components. All your videos are excellent! Thanks!
Very interesting tech / process, and the workers in the factory seem very efficient. Thank you.
1:13 bogus wireless ESD strap spotted! I pointed this out to LCSC once and point them to my debunking video on it and they were embarressed said they'd fix it. Seems not.
I was thinking about that after I watched your "EEVblog 1567 - Wireless ESD Monitor? - The IONA StatIQ Band TESTED" video where you mentioned it ruclips.net/video/Kw7qsVXI8KQ/видео.htmlsi=arF38eKRIY0SfeUl
Would've been okay if it was an ESD floor with ESD footwear but that doesn't seem to be the case.
JLC really has an amazing setup going. I do wonder where they will go in the future---are they going to stick to the cheap, low-end PCBs, or are they going to leverage this huge capacity to do more high-tech things (HDI, more RF stuff, etc).
This is so cool. Thanks for sharing
JLCPCB Provided in affordable and good qualities PCB .
Create a footprint library method is very interesting.
Awesome, you always upload awesome content. thank you for this amazing channel
Thank you very much
That's super awesome!
Hello! You won't make videos about altium anymore?
Where's the remaining of the video 😊
I am still working on it :) ... a lot of work
Love JLC and LCSC.
Amazing 😮
Good to know
I once found a mistake in one of their footprints. They fixed it right away after I emailed them
I have had the same experience, I have seen them improving footprints when creating tutorials
Impressive
I don't know why but I trust this guy whatever he says
:)
What footprints do you all use in altium? I have a library for common stuff but I have a lot of trouble finding footprint on components made by asian suppliers using the manufacturer part search
We create them (or import and customize them)
China is amazing!
Hello, I would like to ask you a question. Regarding high-speed differential pairs, can we refer to the power layer? Will it have a bad impact? Thank you.
I am not Robert, but yes, you can use GND and Power plane as well for reference
Not Robert either. There are 2 main things to keep in mind: impedance (signal integrity) and trace length (length matching). Depending on the noise in the power plane, you may or may not refer to it.
Only if the power plane is the high level of the diff pair. Don't use your 5V plane as reference for your 3v3 diff pair.
This video will help you to understand it better: ruclips.net/video/2UKfWowTvOs/видео.html
@@RobertFeranec From your channel I prefer this one (ruclips.net/video/icRzEZF3eZo/видео.html&si=T-uEHZi0wXSD0KjL). So, if there's no lateral/diagonal disturbance* over the VCC surface of the plane acting as a capacitive impedance match for the diff pair, things should be fine, after all.
disturbance*: strong di/dt return path (picture a diff pair matched to VCC surface whose role is to provide enough power to switching MOSFETs from the same VCC). I hope I clarified my initial statement.
I just found out why the cost of the service.
If the Chinese want to do something and they did, then it is game over for the others😂.
Why only China can do this manufacturing? Why not each country do the same too. So, no need to import from outside. 😅
