This is really cool, thanks for showing the process! One thing I'll note that is in the earlier part of the video, you should the wire bonding to the IC that "mixes the colors" which looks a lot like a ws2811 or similar IC, but in the end, you talk about LEDs that are used for simple christmas lights that use "two wires" which generally do not have controlling ICs, unless I'm missing something.
Hi, the trick is that we can superimpose a digital signal on top of the power signal, this allows us to use just 2 wires, but still communicate digitally
Overall the presentation was really well done and informative. A few points to note, though: 1) The music was louder than the commentary. I had to keep raising and lowering the video at some points of the video, especially at the beginning 2) The camera jitter during panning makes it hard to follow what's going on. It's almost like there are missing frames 3) Maybe a few closer views of some of the work. I know this may not of been possible due to restrictions, but this is more of a request ;) Do you have a video that shows how SMD LED's are made?
Tony Eezi I agree, but it’s not super important for the purpose, these leds are very cheap, you’d see a very different setup in a big brand factory with high power led manufacturing
olsmokey not so true, the process here is to wirebond and cast the LEDs in resin, the number one reason of failure is overheating and running the LEDs with too much current, normally the led doesn’t fail, the powersupply fails. For white leds the running temperature is even more important because the phosphorus cannot handle more than 85 degrees or so if more it will degrade and the conversion efficiency will drop dramatically
I have a couple of questions since you offered. 1.) are the LED’s sorted by light characteristics because they get mixed up in production or is every led produced slightly different from another and they are just sorted to obtain a higher characteristic tolerance. 2.) how much does each LED cost to make? 3.) who invested the money for the machines and how long does it take before one pays for itself. This is very cool to me, thanks for sharing.
Hey man, sure! So these are RGB leds, the dice that are inside are 450 nm (blue) 532nm ( green) and 650nm ( red) they are manufactured separately before assembly. Each led chip is incredibly cheap costing cents only. They are fed in to the machine on wafer boards where the pick and place machine can pick them up and place them inside the led frame. The machines cost quite allot, my estimate is about 50-80 K usd for the placers and wire bonding machines and even much more for the binning machine that sorts the LEDs. So that machine park there costs well over a million usd. ROI depends on market prices for leds and raw material cost. There is a reason why these companies run 24 hours a day, their margins are quite small so all they can do is make massive quantities of leds.
@@infinitesolarforall3901 you have a really cool job, I wish there was more manufacturing like this in the US just because I really like industrial automation but I guess the low profit margins are what keeps that from happening. I've noticed that china is starting to make a lot of machines now (cnc, injection molding, ect.). What do you attribute that to? Do you think China is starting to climb the manufacturing hierarchy? and where do you project most manufacturing to take place in the future. If you had to give one piece of information about Chinese manufacturing and quality control, to me an american engineer who has never been to China, what would it be. Thanks, great video by the way, really appreciate it!
lsm13b the US is still leading in design of new equipment the Chinese pretty much just copy the designs from Japan and US/EU especially in electronics equipment the US can’t be beaten as of now but the Chinese make stuff cheaper.
lsm13b The probability that LEDs are 100% identical is very low. There will always be manufacturing tolerances. These tolerances can be from clearly visible to barely visible. You could see that in the exam at 6:15, how the point between the 4 categories jumped criss-cross.
I'm surprised that the IC only does "slow flash" color transition in the same speed as others which is boring and too quick, also it is not a seamless transition, as the programmer mise have been careless. Could the IC be programmed to be much slower with higher steps per second resolution?
If it's like other IC LEDs the data gets cascaded to each LED. The first LED receives it's data then it allows data to pass on to the next LED and so on.
@@unlokia I've seen lots of manufacturing facilities in my days, and I can tell you right now any real LED manufacturer worth their salt maintains a pristine environment, this is not a well run operation. The amount of filth and contamination in that facility is horrid from an electronics manufacturers point of view, you do understand that dust and grime in/on small components causes quality control issues right?
Whats name of music? Nice representation mate, but as someone below suggested, i expected much more cleaniness there. Are they also producing dices there or are they getting it pre-cutted, readt for bonding?
Nice video.. I'm interested in the company making these, as I have wanted to buy them for years and can't source them. do you have details you can share?
@@infinitesolarforall3901 not 2 wire addressable RGB pixels... they are as rare as the dodo. I thought twinkly cornered the market on them, which is why I was excited :)
Hi there Tarinder, im not sure what this machine costs, but you need several machines to complete the process, for LED strips they make SMD LED's that are then soldered to the flexible PCB of the strip. that strip is than coated with a silicone to water proof it and make it last. for that production process you can also use just an SMT machine, and a glue machine. you dont have to own the LED assembly machines.
I know the colours require different processes, but just imagine the assembly cost saving if the LEDs and control chip were all integrated into one die.
You could maybe fuse the dies directly on the chip (maybe at the chip fab?), but this would make the chip bigger and thus more expensive, and you'd still need to run each one through the stitching machine to connect the chip to the pins.
Just had a crazy idea tho. chip features are much smaller than the wavelength of visible light, so maybe you could make a phased array and transmit light as a radio? (quick calc 800nm red light = 300+ petahertz so maybe not this year)
John Vatic in a way it is it uses the I2C protocol for communicating with another chip so it’s colors can be controlled. 256 steps of intensity per color. It’s used mainly for decorative purposes and saves allot of copper
jonathan lavezzi vote with the dollar.... reason this is happening is because people seem to addicted to cheap. Also death of the middle class in the USA is part and parcel of this most people are hurting financially
A superficial study. I learnt very little. There was an error in the voice-over too. White LEDs have phosphor, not "phosphorus". The repetitive whacky music was an annoying distraction too.
Peter Jameson “yawn” yeah yeah best captains on the shore and all that, can it be done better? Go for it man, go do it, show how good you are at this, share your knowledge
@@infinitesolarforall3901 Thank you for getting back to me. My criticism was polite and constructive and I ask you to simply consider it for future reference. It was not my intention to berate you. I appreciate that it takes a great effort to make a video and amongst other things your editing, presentation and voice-over was very good and I thank you for that. Perhaps I should have mentioned that in the first instance. However your video shows LEDs being assembled by amazing machines but very little of the intricacies, which is what I wanted to know.

Tony Eezi I agree, but it’s not super important for the purpose, these leds are very cheap, you’d see a very different setup in a big brand factory with high power led manufacturing
This is why so many LEDs are unreliable. They quote figures of 10's of thousands of hours, but in practice it's much less.
olsmokey not so true, the process here is to wirebond and cast the LEDs in resin, the number one reason of failure is overheating and running the LEDs with too much current, normally the led doesn’t fail, the powersupply fails. For white leds the running temperature is even more important because the phosphorus cannot handle more than 85 degrees or so if more it will degrade and the conversion efficiency will drop dramatically
No fucking reason to manufacture these units in a clean room lol
Well, by my direct experience I replace many dead LEDs weekly. Maybe these ones are reliable, but the ones I have to replace aren't.
I have a couple of questions since you offered. 1.) are the LED’s sorted by light characteristics because they get mixed up in production or is every led produced slightly different from another and they are just sorted to obtain a higher characteristic tolerance. 2.) how much does each LED cost to make? 3.) who invested the money for the machines and how long does it take before one pays for itself.

What do you send me.. quantity 50000??.
Can I buy this
I know the colours require different processes, but just imagine the assembly cost saving if the LEDs and control chip were all integrated into one die.
Impossible at today's technology. Each color requires different type of semiconductor. The chip must be made of silicon.
You could maybe fuse the dies directly on the chip (maybe at the chip fab?), but this would make the chip bigger and thus more expensive, and you'd still need to run each one through the stitching machine to connect the chip to the pins.
The differences in coefficients of expansion between the various semiconductors causes problems in chip-on-chip fab.
fair point. There's also the problem of heat dissipation
Just had a crazy idea tho. chip features are much smaller than the wavelength of visible light, so maybe you could make a phased array and transmit light as a radio? (quick calc 800nm red light = 300+ petahertz so maybe not this year)
