Beautiful machinery and engineering - those pick and place robots are crazy - and so good to see relatively current LED manufacturing. It's a pretty wild process. I really liked the music choice and lack of narration in the video, too.

nice joke 😄 I rofl out of the people, that are seakig Philosopher's stone in manufacture process. It’s very strange to see people who still don’t understand that the key to successful production lies in people and the organization between them.
Super impressive! It's amazing how every tiny LED is binned for color and tested multiple times. Also the longevity testing in those ovens really impressed me.
Ovens are literally there to... bake stuff. Where did you even get longevity testing by OVENS?! First baking is to solder the chip to substrate, the second is to bake the luminophor layer (that orange goo).
@@Noobochok Yeah but time is everything. All SMD electronics are baked in an oven, but the temperature ramps and times are followed very accurately. It's minutes, not hours. So every silicon chip is pretty much good for 150 degrees C for a few minutes or more, but not hours and days. LEDs can operate at very high temperatures so I guess it matters a lot.

@@Twitch_Moderator Now I'm wondering where the inferior quality is. Have you ever thought that the LEDs that create the backlight in your television come from Asia and it doesn't matter whether it is manufactured in America, Europe, Russia or somewhere else. Maybe even Samsung, LG and whatever the big brands are called can order their LED needs there. Hardly any manufacturer makes these themselves today, and your LED strips are equipped with LEDs, resistors, capacitors, etc. from Asia, even if they say "Made in America" etc. at the end, the components are purchased much cheaper.
it probably is chatGPT comment. Sure thing it's low quality and there are many errors as visible on the video. Chinese govt tries to dump the global market by subsidizing low prices and destroying competition but what customer ultimately gets is stolen outdated R&D so no progress and inferior end product.

Important to know. I'm working at Taiwan at a REAL LED chips production that is actually HIGH END. Looking at the technique used in this video shows the lack of advanced equipment used in the latest production chain. Don't thrust what anything you watch or read online.
Concerns arise over the environmental impact of mass production machines used in LED chip manufacturing, particularly regarding energy consumption and waste generation.
You haven't shown the machi mochines names, and also this factory does the frontend process, what about the backend process that is photolithography, mask design, substrates deposition ?
You rarely see clean rooms where gloves are not required. I would guess their LEDs should have a higher than normal failure rate from contamination but maybe the gloves are more expensive than throwing out failed LEDs.
Like another commenter said, the full bunny suits everywhere and air showers before entering the cleanroom, but no gloves on anyone anywhere is kind of weird. The hands, aside from the hair, are the largest source of contamination and extraneous particles in a cleanroom environment. I really do not understand what's going on at 5:50. Why are they BREAKING the gold bond wires going to the chips??
The semiconductor is already finished at this stage, so the contamination by hand is negligible, it's not that sensitive. The chip is literally drowned in phosphorus resin later on, so a few particles will not damage it. Ofc in a semiconductor manufacturing plant everyone has to wear gloves, the structures are so tiny that a spec of dust will make a chip inoperable.
@@them0leisback Wouldn't a particle of water from the humidity of a finger be trapped in the resin later on, and explode when it gets hot enough? These LEDs have specs of 20k-50k hours, and I often see them fail after a couple of years of use (non-continuous).
Did work for Philips back in the 90's making 1 chip TV's, if i remember it correctly it was minimum a cleanroom class 10, which means we had to wear also those blue suits but there we must also wear special gloves and special glasses. It was forbidden to enter that clean room without those special gloves and glasses caus human skinflakes and hair can destroy a lot of wafers and or batches of wafers specially when they are contaminated right before going into the furnace. So for me it's strange to see that those people don't wear any gloves and the special glasses.
first I thought like ohh so cool, so interesting and so satisfying. but then the video turned out to be slightly horrific to me to watch because I was imagining myself to work there and be surrounded by all those extremely loud noises every single day. I would freak out after 3 days
I suppose it’s like a coin flip. Heads or tails? Those that landed tails get blown out of the conveyor belt. And then fed back in again and again, until it finally lands on heads.
The use of mass production machines in LED chip manufacturing underscores the need for rigorous quality control measures to ensure product reliability and longevity.
That jumped out to me as well. It’s like they have all these procedures but you’re going to get dead skin cells, hair, and oils all over the place because, no gloves. SMH

I don't get your point, is it a problem if a chair is made of plastic? Does it improve the production process if it was a more expensive chair? Like wtf are you talking about 😂😂
What is going on with the expanding blue film at 2:30? It looks like those are the chips that are then used for the LEDs-- is that how they come? What is the purpose of that?
Those are the bare LED's that come from the semiconductor fab before they are packaged on the metal plates and before bond wires and phosphor coating is applied. They're manufactured in a small area then the blue film stretches to allow the grabber to do its thing.
In another TH-cam video they explain this expanding blue film… it’s to create greater separation between the chips. So when the robotic arm picks one chip up, it doesn’t knock into the neighbouring chips. Basically the chips are made close together, the blue film stretches them apart and then a robotic arm picks them up one at a time. What this video didn’t show is. The robotic arm sensor can detect which chips are good and which are faulty, so the robotic arm only picks up the good ones.
If you're calling this "high end" please show us what low end looks like. Cause this looks like the "standard" LED manufacturing process lol Due to the nature of LED manufacturing, all LED manufacturers are high end
Proponents argue that mass production machines enable China to maintain its competitive edge in the LED industry by streamlining production processes and reducing lead times.
My god, how are they working without gloves? Hair and dead skin shades from our hands all the time. And this isn't sarcasm. I worked in the cleanroom in the past.

I always wonder what the work drama is like in these places... how dare she, I was supposed to be at the glue mixing station today, or Ugh I hate working with him he always leaves such a mess at the vacuum sealing station.
The yellow is just a layer that turns the blue light coming from the LED into a broad range of wavelengths, which makes white light. Every white LED is just a blue LED with that yellow phosphor coating it.
