What gobsmacked me is that yesterday I was looking for a video on the production of 5050 / ws2812b LED strips and matrices. Found nothing. Then this video was posted by this guy. He read my mind.
Hi! I use Samsung lm301h diodes and I heard good things about lm301h EVO for horticultural purposes because of the high efficiency...lumen per watt are some of the highest on those diodes...Is WS have better and cheaper diodes?
How do they even make these machines that manufacture all sorts of tiny things? Are they made bespoke for each factory? And considering how cheap certain products need to be made, what are the costs involved making or buying such a special machine? They seem so specialised and have to operate at great speed and accuracy. It's mind blowing really what we can do, and there has to be people out there that innately understand where technology has progressed to invent machines that operate at the cutting edge of technology. There has to be technology out there that has been invented but the manufacturing technology to make it then has to catch up to try and make it viable. I wonder how big that lag is?
@@Diode5High speed assembly and packaging has been a staple of the industry for decades. These are small machines. Some of the lines are both massive and massively complex.
yeah I have seen tons of manufacturing videos showcasing mind blowing machines, but I have not yet seen a video that goes into the design, production and testing of these machines! @@Diode5
Great video! This learned me appreciate the relative high price for these leds. The faster larger double pick and place machine was insane, never seen one with such long arms operate so precise at that speed.
This may be my favorite factory yet! Super high tech, but still very easy to understand, and those machines are wild! It's crazy to see how fast they AND precise they are, to pick up stuff smaller than fine sand, and nail it thousands of times per hour! Scotty, the camera work in this video is sublime, your narration is tight, interesting and emotive, just all around the crème de la crème of factory tours here.
I'm not finding the factory easy to understand. Lots of info about how wires are adhered to things, how things are sorted, no explanation of how the things are made.
WS2812B LEDs are the thing that GOT me into electronics. they are fascinating little gemstones haha this is a very very cool tour, and im glad to see so much of the process. also Scotty, you giving the FULL tour and overview yourself is surprisingly great! i expected having the 'expert' or 'engineer' there to speak up was the best way, but it turns out just having you do and explain all of it yourself is much better in my opinion. either way i LOVE these factory tours!!
I remember the first time seeing a blue LED. 💙 very dim about that color. Cost about 12 bucks from a surplus mail order place in the early 90s. Now they have extremely bright ones used in disposable stuff.😂 and some power LEDs rated at multiple watts optical power😮
I was the first person doing residential LEDs on Long Island (NY)-back in 2009 and I'm blown away at how far these things have come. But what really impresses me are the machines that make these LEDs (and many other objects). No one else ever talks about or seems interested in the incredible machines and the men who design and companies that build them. Perhaps Strange Parts could do some stories/videos about that???
That's incredible how fast and accurate those machines are. It's amazing that people still assume that anything made in China is low quality. I use thousands of these addressable LEDs and have only seen 1 fail.
Well he said in the video the ones that don't make the grade are sold off cheaply. So of course if a buyer is looking for the cheapest option, a low quality part from China is going to come up when they're one of the few countries willing to sell seconds. So on the one hand it's good they sell them instead of dumping them in landfill, but on the other hand it means they end up with a reputation of producing low quality products, when really it's just because people are buying them cheap not realising they failed some manufacturing test. If they were more clearly marked and sold as seconds I think it would improve their reputation, but too many people are willing to buy them and sell them as a premium product.
On top of my head I can only think of one and that is SpaceX, but I have seen a lot of videos from other western companies that have invited youtubers to the factory floor and one of them I remember was a dyestamping factory and I think it was Alec Steele who was showing it. But you gotta go and watch Tim Dodd on one of the multiple tours to SpaceX (yes, multiple times when Elon Musk personally shows off the details of their newest engine improvements) ☺️
Dude this was one of the coolest factory tours ever made! I have a few thousand of these LED and I always wondered about how they make them. Thank you for the insight and your ability to gain access to such awesome factories.
One of the best explanation videos of this process I've ever seen. Clearly the factory is experienced and proud of their process (rightfully so), I'm amazed.
As an American I want to say that I appreciate the hard work of the common Chinese worker. It's not lost of some of us that Chinese quality has gotten better and better because this high-end trade work is becoming multi generational. Serious care and thought has gone into teaching the next generation.
This is awesome. Knowing quite a bit about semiconductor manufacturing, it always amazed me how every single one of these LEDs worked. I honestly didn't expect 100% inspection but it makes sense. The little comment about the rejects getting sold at a big discount is a bit concerning as that would explain shady too good to be true priced versions that work, but just not as well.
It makes sense for certain products, if you're just messing around with some LED tape you probably don't care if some of the LEDs are 10% too bright, but it becomes an issue when it's not communicated properly, which happens too often.
Ive played around with so many types of smd leds over the years and as they have advanced it has fascinated me how everything is on chip. Insane to see how it's done. Thanks for the inside look
Strange Parts does the best factory tour videos and this one was so well done. I had no idea there were so many steps into making neopixels. seems like half of the steps is orientation!
IM always amazed at the manufacturing machines.. who made it.. how did they figure it out.. what were the problems they had to solve while inventing a machine that has never been made before. need a deeper dive into the people who make the machines that make machines! thanks Scotty this was very educational.
These machines are made by real heroes whom most of us will never know. Unlike celebrities or political leaders, these heroes never brag and work silently in the background
Humble? No, not really. CCP China LOVES to gloat about their "achievements" in their State-controlled media. Chinese, manufacturers specifically, just aren't quick to talk about who & how they bribed/copied/stole from to obtain the technology.
Good to see you looking well now, and so cool to see this. Waiting for a batch of boards from JLC with 2812's at the moment, and 👍 to them for facilitating.
This video was really interesting! You explained all the steps very well, and I appreciate that there was no one speaking Chinese, as this can create a break in the flow imo. The flow was good and took us from the very beginning to the very end. Good job, and I hope to see more!
It's insane the machines humans can build, mind boggling speed and precision at a microscopic level. I'm surprised that they cut the LED's into individual units so early in the process.
What I notice when watching this is how FEW PEOPLE there are. This level of automation has basically done away with the vast majority of human involvement. Keeps the price way down to be sure, and this really is a game changer. What it underscores is how (at least in this kind of manufacturing) the blue-collar labor force is essentially eliminated. It also shows why mom-and-pop firms have no chance of competing. Impressive and scary at the same time.
I appreciate that you are back to doing the factory tours as those are some of my favorite videos that you make. I enjoy just watching the bowl feeders etc run. The pick n place arm for those leds looks like the biggest harddrive arm ever made...
I am so happy that we are finally back to being able to tour a lot of manufacturing places again! Been following for almost 5-6 years. Thanks for another great video!
WTF!!! You literally posted this video a few hours before I was wondering if there exists a video about the production of addressable LEDs, while I was writing a program to drive a ws2812b matrix.... And yours is the ONLY one that exists! INCREDIBLE.
Cool. I've been using their LEDs and standalone controller ICs. Pretty neat how they work on the application level. And even cooler how they are manufactured. Thanks for sharing.
The 2812b requires exact timing though. Any runtime delay of more than 1 millisecond will result in the strip not displaying properly. So it's important you either use PIO for transmitting data, or you have a mega stable computer/application with razor sharp timings. I recently built a matrix text scroller driven by a raspberry pi pico and had its on board PIO do the data transmission while the application starts on the next frame.
@@paulmichaelfreedman8334 I'm on STM32, been using some of its timers in PWM generation mode powered by DMA, so precise timing isn't an issue. I can easily drive several WS2812B strips simultaneously with thousands of LEDs and have them refreshing live from a display buffer. The issue with the 2812 die is that it doesn't seem to be gamma corrected, and the 2811 chips don't seem to be able to generate pure high level or low level in DC form. There's aways a little spike regardless of the load resistance. Some of my applications don't exactly use these outputs to drive LEDs.
I'm so amazed at these arms being both stupidly fast and incredibly precise. I always thought you could either be fast or precise, but not both. Thank you so much for showing this, i'm instantly subscribing.
Fun fact: the reels used for component packing are based on earlier film reels. You can take a reel of LED tape and it will mount directly to the hub of an 8mm projector.
Interesting insight into the manufacturing process of individually addressable full-color LEDs! The level of precision and automation is impressive. Very transparency in showcasing the production. 🌈💡
Also, they are in FlaschenTaschen :) Thanks for this tour, this is incredibly fascinating how fast these things are happening in production, and how accurate. Interesting that some of the pick-and-place machines essentially use an oversized harddisk arm.
When I saw those little pick and place machines my jaw literally hit the floor. I cannot, simply cannot believe that something so fast can be so accurate for so long, presumably thousand and thousands of cycles. Like those chips are so fucking small you cant even see them without a microscope! It's actual black magic.
Stretching foil trick dropped my jaw... Either way mesmerizing. Who do I call when I spend 20 minutes watching, feel like it took 2 minutes and already got withdrawal syndrome?
Thanks! I've worked at hi-rel IC houses in the 70's & 80's, so nothing you said went over my head, and it's just so great to get this kind of access to companies making things I'm interested in!
The LED lead frame with the over molding that you showed was super interesting. Did they tell you anything about their lead frame supplier or about their wafer fab?
Fantastic video, just amazing detail and complexity involved in making LEDs, I'm interested in who makes the machines? The design of the machines is equally impressive. Interesting that the computer screens were still using windows xp!
I havent caught up on your health journey (mostly bc youtube hasnt recommended it...) but im so happy to see you back at it, your videos provide incredible value and im so glad to see this one pop up
I absolutely love this channel and how you take a look at tech like this, especially in the factories. Thank you for the look at things that people would never normally see.
I think it would be worth mentioning that he actually has to talk over the noise of the machines to be audible - I'm sure he has a pretty rough voice after each one of these. Fantastic effort by him and his team, especially by including low speed sections of machines that make hundreds of movements per second. I'm old enough to recall the appearance of the first SMDs (and meeting the challenge of manually soldering them as a hobbyist😋)..
During the last video, I was wondering how those component tape reals were made, particularly with such small components. At the end of this video I realized I got exactly my wish.
Amazing stuff.. whenever I think LED I always picture the classic type with two wires sticking out. Seeing this is amazing, the LED technology we have is crazy.. I’ve had an OLED TV for a few years and that still blows my mind how small they are.
Manufacturing-wise, an OLED display has nothing in common with discrete LEDs. Your OLED TV is not manufactured by mounting individual LEDs, it’s basically a glass panel printed with many layers of special inks. (Super oversimplified, but the key is that it’s made as a single part, with all the individual subpixels manufactured simultaneously, just the way that all the billions of transistors in a microprocessor are made together as an integrated unit, not added one by one.) Displays made of individual LEDs do exist, as video walls. These are available with a dot pitch of as little as 0.84mm, but even that tiny pitch makes for a 145” 4K display, over 3.2m wide. Shrinking that approach down to household TV sizes is being experimented with, under the name “micro LED display”. But they haven’t been commercialized yet.
Really fascinating how these machines manages to be both fast and delicate. Even more impressive when you realize most of these are also made in China (would love to see a video about these, specially the wafer handling ones). The only frightening stuff is how often these seems to run very old Windows versions like Windows XP or maybe even 2000 (in fairness, it's fairly common in industrial equipment) ^^.
@@Hamstr_Games Some factory software can do fine using DOS, Unix or Linux. The less unnecessary stuffs in the way the more reliable the software operation.
Great video, thank you. You look great and your energy is inspiring. This is the first video of you I saw after your accident and I am so glad to see your energy back. Now I go and watch what I missed, All the best to you!
Dude! I haven't seen your videos in forever. I think at one point the internet community thought you stop using the internet or something. I am so glad you are back. I really love your videos. Looking forward to more videos!
I can honestly say I kept getting frustrated when the ads ran as I was so enthralled in this video. It's just utterly amazing how these LEDs are made and assembled. I enjoy watching your videos so keep up the great work.
As a controls person seeing the amount of automation required for those machines is insane. The amount of components that need to be calibrated correctly to run 24/7 with minimal defects, mind blowing.
FINALLY, a awesome video out from SP! I Love it. Sadly the last couple of vids have been meh. But this one OH MAN! great stuff. this was a fun video to watch.

Manufacturing-wise, an OLED display has nothing in common with discrete LEDs. Your OLED TV is not manufactured by mounting individual LEDs, it’s basically a glass panel printed with many layers of special inks. (Super oversimplified, but the key is that it’s made as a single part, with all the individual subpixels manufactured simultaneously, just the way that all the billions of transistors in a microprocessor are made together as an integrated unit, not added one by one.)
Displays made of individual LEDs do exist, as video walls. These are available with a dot pitch of as little as 0.84mm, but even that tiny pitch makes for a 145” 4K display, over 3.2m wide. Shrinking that approach down to household TV sizes is being experimented with, under the name “micro LED display”. But they haven’t been commercialized yet.
The stretching tape technique is truly fascinating.
Really fascinating how these machines manages to be both fast and delicate. Even more impressive when you realize most of these are also made in China (would love to see a video about these, specially the wafer handling ones). The only frightening stuff is how often these seems to run very old Windows versions like Windows XP or maybe even 2000 (in fairness, it's fairly common in industrial equipment) ^^.

Some factory software can do fine using DOS, Unix or Linux. The less unnecessary stuffs in the way the more reliable the software operation.
It's more secure on average. And most of the time these machines are never connected to the internet, heck not even to any network.
Amazing video! You explained everything so well! Straightforward, thorough and easy to follow.
Just so happy to see you recovered and walking around like before!!!
"Thank you Ben stewart for supporting on patreon" did anyone see that?
This was honestly even cooler to watch than the amd and intel factory tours i've seen so far, honestly, cooler than any factory tour i've seen!
That tape and frame technique is amazing. Very creative solution
This was really awesome. I loved seeing the vibration pot.
I'm so happy to see you have recovered from your head injury and this videos is giving me old school vibes.
Great video, thank you. You look great and your energy is inspiring. This is the first video of you I saw after your accident and I am so glad to see your energy back. Now I go and watch what I missed, All the best to you!
Dude! I haven't seen your videos in forever. I think at one point the internet community thought you stop using the internet or something. I am so glad you are back. I really love your videos. Looking forward to more videos!
The machines are absurdly cool, they could be making pencil sharpeners for all I care, the precision and speed is impressive.
The level of automation is amazing, thank you for showing this!
It's staggering to see how quick those machines work, the mechanics must be so precise
The automated picker/placers are so precise!! have to appreciate the steppers controlling them
I can honestly say I kept getting frustrated when the ads ran as I was so enthralled in this video. It's just utterly amazing how these LEDs are made and assembled. I enjoy watching your videos so keep up the great work.
Amazing video - the shots are getting better and better and the narration ever smoother!
Good to see you back, hope you're feeling better.
Incredible technology at almost every stage of the process. The tiny size of those chips is amazing.
As a controls person seeing the amount of automation required for those machines is insane. The amount of components that need to be calibrated correctly to run 24/7 with minimal defects, mind blowing.
I have their LEDs all over the place. Amazing product, amazing factory, thanks for doing the video!
This is so awesome. Thank you so much for doing these. My kids and I are always so excited when you put out a new video!
Thought it was not interesting, it was VERY VERY interesting, keep up the work!
Absolutely incredible how fast, precise and intelligent these things are happening.
FINALLY, a awesome video out from SP! I Love it. Sadly the last couple of vids have been meh. But this one OH MAN! great stuff. this was a fun video to watch.
Wow ! Thanks for the visit !!
I love these series of how it's made.
Surprised and super impressed with the speed & precision of some of those machines, wow
