12:06 I like how that resistor floats away and then snaps into place
You can tell that spindle has zero runout. Beautiful.
Soldering with hot air is so satisfying step for an Electronics Engineer
Dgh
Can I ask a question?
I want to take an engineering course.
I am confused between electronics and electrical engineering.
Your results are absolutely incredible. The precision in milling the soldermask off was awesome.
Awesome stuff! Local prototyping would have saved me a lot of time! And then I saw the price...
Your wallet pointed a gun to your head?
whats the prob, go diy
Ita very cheap if you buy this from a store
@@AmirWaisblay from what store?
@@ilyas.7209 heaven
I’m not 100% sure what I just watched but it was amazing!
I don't know what to say... This is so perfect. A VERY NEAT AND CLEAN PCB. i love it.
Holy cow!!! Never seen a man using copper rivet for through hole.
That's a thing I saw it in a document like IPC standards a decade ago
used be a PCB manufacturing engineer for over 15years and
you have my respect!!
Y do we use copper rivets?
@@BilalKhan-do9il They r for connecting top and bottom side
PCB manufacturing process has copper plating instead
@@rjsdn0506 oh got it, thanks
Спасибо! Эстетический оргазм получен. 13 минут наслождения!
Distributed manufacturing and classical music, two of my favorite things in the same place! :)
Everything in the video is amazing. This is a work of art. I watched it without getting tired of it, it caressed my soul.
The finished pcb was great looking. The camera-like parts attached to the board and functioning was a winner project for showcasing the pcb at the end.
Damn, it's so perfect that it looks like a render.
12:10 that self alignment is awesome!💥
The best PCB making i had watch in my entire life 🔥
Oddly satisfying to watch it mill out the board and it turned out amazing.
Most beautiful art I have ever seen
I watched a lot of videos like this, but this is perfect and the best job.
It's beautiful.
I've looked at this for five hours now.
I have 3 words - absolute professional beauty
This thing is so beautifully satisfying!
like a masterpiece. it's like a work of art!!
The drill has a marvellous dance on the pcb floor & the BGM
Bought 2 week ago. Is fantastic because it prints exactly as shown in the videos, without any adjustment, just out of the box, plug and play
I was thinking about getting one but the price is quite prohibitive. The drill bits are specific or can be replaced?
@@GuilhermeGomes2 can be replaced with anyone you want, if i remember correctly, spindle diameter is 3.75mm , any drill compatible with this size would be ok. Price is high but i assure you that with a normal CNC lost time to set it up is much longer! At the same time is convenient if you have a company or work for/on it and you need fast prototyping, if not, a normal CNC like 3018 (200€) , with fine tuning, can reach the same results ..
It seems impossible to me that the Z axis is perfect, it always has the same depth, this is one of the problems I have always had on my CNC. The trick of the spring to remove the mask is very ingenious. The video is totally addictive.
you can create a depth grid of your PCB so that even if its not perfectly flat, the Z-axis will compensate the error and stay relativly flat to the PCB
But yes the accuracy of his cut depth is really stable
Does anyone know how this works with the spring? I also noticed it. Is the engraving bit just loose in the holder, with the spring on top of it?
Even if the Z-axis can be held accurately, I feel the best way to remove the solder mask from pads is with a laser. But then you need to invest in a laser….
I would definitely consider this as *ART*
Tschaikowski + PCB prototyping = masterpiece of art
Hmmm, maybe I'll try that method. I always find the acid is hardest at the center of the board, especially on double-sided boards.
Impressed.
very good demonstration. good job. and those rivet type vias... a big respect.
Realmente una obra de arte, que pasión, verdaderamente emocionante!!!!
A miracle in the making. Truly a masterpiece 😍
Fitting music for this glorious creation. Nice job!
Excellent video! nice demostration.
hello sir . I love u .
Whell, that was like brain porn.
Well done. Truly an outstanding job. Better than factory.
You have a great engineer. Congrats on the good job..
Mi inchino a così tanta bellezza , non c’è cosa più bella dell’elettronica!
I dont know why i am watching this to the end.
its beutaful
Where is the diy lasercut stencil/similar? Beautiful pcb fab and paste looks fine after reflow but the perfection in the rest of the process would go nicely with perfect paste application as well ;)
Love it..... I forgot everything while watching... Just amazing
Informative. Useful. Calming. Inspiring. Life-changing. Enjoyable. Heart-warming. Other.
love the video, very mesmerizing.
Thank you for your kind words! I'm glad you enjoyed the video and found it mesmerizing. Your support means a lot to me. If you have any questions or suggestions for future videos, feel free to let me know. Thanks again for watching!
Sensational!!!
Beautiful, complex, amazing. I tried to use milling for valve designs and bumped into parasite capacitance. It was solved by splitting of solid areas into smaller pieces.
Extremely Awesome !! It´s the best video I´ve seen this year. Excellent !!
this is art
ART!
Amazing Workmanship!!! WoW
The best pcb machine, I'm dying to have a Wegstr
Very nice, but what was the thickness of the copper clad?
Hi and thank's for your video.
Can you mill as an example QFN-38-1EP_5x7mm_Pitch0.5mm.
It is one the packages that uses the chip LT8705 which is a DC=>DC boost-buck converter specialized for
varying input voltages.
On the manufacturer site you may download the datasheet and you have a precise package
description at pages 41 and 42.
Thank you very much in advance. Have a nice day.
Just one word, Brilliant!!
Technology to make electrical circuits great
Everyone through the channel I see to support. Thank you

This is just techno porn. Incredible.
Absolutely amazing!
I have enjoyed watching it. A piece of art.
Hello, good job, what fluid are you using for tinning bath.
Tinning bath CL-1 - currentless, for copper and copper alloys
Excellent. but what exactly was that final product ???
I think it was nothing. Just showing the process
Wonderful work, bringing ideas! Thanks!
Such a nice work, man. Awesome!!!
This is video is a beautiful. The machine CNC it looks excellent, but I think is for hobby amator is to expensive. In Poland the price machine is 5 or 6 salary normal worker. Please note that this is for hobbyist. But the video and what wegstr. com does is beautiful. When I have bad mood, I watch on video and it's much better.
yea, i design\develop pcb's as well, this sure is beautifull, but somehow in my live its a whole lot messier ;)
Verry Good
And very neat work I appreciate all the background and music and you hard work stuff.
This video is just art!! amazing
Good job 👌 but a music come sleep ☺️
The only problem with this milling technology is that the remaining copper chunks between the actual routes become capacitor and indicator at higher frequencies. These unwanted capacitors and indicators become completely unacceptable and the circuit response will be totally wrong. Other than this issue, if you want to implement a design at low frequency, it's perfect imop
This is only a problem for sensitive circuits like RF (radio frequency) and capacitive touch sense. For 98% of circuits, leaving the extra copper in the board makes no difference.
You can mill away the extra copper also - though it will not look as nice
@@coltennabers634 yes I cut the extra copper. But it's very time consuming and not worth it
They could have also tried to stitch the floating copper to ground using vias but considering they had to rivet each via it would be time consuming.
I am not even sure if they had a ground plane on the back side and if they did they cut it up too much with all the plane hops/traces on the back.
Notice how they ended up having to tilt the RF module off the board even though there was a cutout for the pcb antenna. That board is probably producing a lot of EMI considering all the floating copper that is around like you mentioned.
You could argue it doesn’t matter for digital or low speed circuits but with rise times decreasing and they wanted to put an RF module with pcb antenna, they should have followed more signal integrity guidelines when doing the layout.
Awesome stuff. 💪
Thank you so much for sharing
I enjoyed every second and laughed at the end 😄
Which software is used in this field of making PC
It says @0:18, Sprint Layout for drawing the PCB, and cut 2D to convert it to CNC g-code
👍👍👍👍👍
Привет! у меня твой комментарий первый)
6:07 wonderful music ❤️
Amazing! What great skills and expertise!
That build plate is overexposed for a reason. They are hiding the damage that will be inevitable from trimming the board. Also, ask yourself why you never see the surface finish of the copper after the solder mask is etched all in one take. (they aren't even blowing the debris away with the air nozzle you can see in the shot) They have meticulously finished each pad by hand to give it an unrealistically smooth surface finish. Resetting that board on the build plate (not to mention leveling it) would be a right pain in the ass. Also, you cant hear it... fucker will be loud.
30-50W fiber laser should do a better job i think
The build plate is untouched. you usually use a 'sacrificial' board on any cnc that can be easily replaced. They have a video of the copper after the solder mask is machined off by the cnc, it's not super clean but it looks much smoother and has a much better finish after tinning, as they show above. When putting the board back on for secondary machining, you don't autolevel again, you use the same profile as when you did the primary machining, the board hasn't gone through any process to warp its profile so it will have the same profile as before. The motor has a whining sound, but you can quite easily have a conversation right next to it without straining,
This machine looks really good, but I don’t want to sell my kidneys to buy this machine. I like my kidneys ;(
you surely do, but others will like them more and better
You don't have to sell your kidneys, you can sell only ine of them
@@AmirWaisblay I'd like to have both of my kidneys.
@@Shrekcraft oh so you screwd
@Mr Guru I know. The downside is it takes time for it to arrive.
Nice making of printplates, thanks for this video, and kind regards
Love the music while watching the vid
Mill a damn solder paste stencil instead of just blobbing on solder paste. You already have a machine for it!!
Why though tbh? hes doing a decent enough job with the dispensing on his own, why spend the money on that part when he doesnt need to? someone like GreatScott however would benefit from a stencil, and some flux, and a more humble attitude, and more knowledge, and uh, a lot tbh. i dont like greatscott
@@liveen Agree about greatscott. I find him annoyingly arrogant. The reason I say to mill a stencil is that he has the machine. I photochemically make mine. Works well enough but in all honesty I now just buy them with my PCBs as it's cheaper and they are laser accurate.
@@pentachronic Yeah for me personally its just that it seems like a waste of money when that same metal could be milled into something more useful :P considering this video ended with a literal circus board I think not using a stencil would be good hahah
A thing of beauty is a joy forever!
your videos are insane as always
Music is annoying ... but PCB is very nice :)
I dont get the hate here. OBVIOUSLY this isnt going to compete with multi bilion dollar factories. Sometimes doing it by hand or in a small scale like this has no other reason other than to show how it can be made, the charm of it and it may just nip that itch OP has felt when working on their own projects.
I find this to be really beautiful and inspiring and its fine if thats all it will ever be. Its obviously a functional board and i dont think il ever do it myself but still.
i thinks people just complain because the machine is extremely overpriced for a hobbyist. at 3 grand, you are kinda rivaling probably a sevaral years of spending on jlc pcb o pcbway
Excelente proceso. Saludos de Argentina
Nice work. Beatiful video.
Congrats. Keep uploading videos. Cheers from Argentina.
I believe that device you just made is from 2050+ and It can see through walls and clothes....
भाई यह बनाया क्या यह तो बता दो
Man... You really jenius at it!!! Awesome
The future of pcb manufacturing
Ha-ha!
Ай-яй-яй! На таком размере стеклотекстолита три таких платы можно было сделать. Никакой экономии!
Or you could order the board from JLC for $0.40 and have it in a week.
A week is a long time for a developer unless they have a different customer project they can work on while they wait.
@@perwestermark8920 True, for profesional prototyping you need your board right now, not in a week
Nice video. And it shows to me how hard is a PCB board is being made.
There are several methods to made a PCB, and I don't think that it is hard. I'm personally use a thermal transfer method. What I really hate in whole process is hand-milling holes in PCBs.
It’s kind of funny how there’s so many ads within this video, which is an ad in itself. Haha
But hey, good way to make a little extra money from those of us that can’t afford to buy one of these machines. And it is fun to watch.
The prettiest useless PCB in history :D
😂😂😂😂😂😂😂😂😂😂😂😂😭
Why do you think so?)
It's more useful than your hobby PCBs tho.
It's demonstrating a company's product so it's very useful.
Lol
Demo
आप की जितनी तारीफ की जाए कम है सर आप के लिए तो शब्द हि नहीं है मेरे पास🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🥰🥰🥰🥰
Amazing, the resistance can automatically go its position when soldering.
Or you can save a ton of money and time and get your PCB's from JLCPCB and similar places.
It's for prototyping. Waiting 5 days for on the mail is too much.
better than sex
Seems like a dream. Very nice!
Awesome.
Greetings from Brazil.
pcb = porned circuit board
You did a good job? but it is not useful in engineering life 👲
why not?
Я остался в восторге от просмотренного видео.Просто красавчик.
