High-End Manufacturing: LED Chips Mass Production in China

[@paolo11x11]

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.

[@屁屁牛]

well as an engineer who really went to those factories, I will tell you that working with the noise and smell is not beautiful at all

Without you amazing people in China, millions of DIYers in the West would never be able to develop the projects they have always dreamed of because they would not have been able to afford the tools, equipment, and parts. I personally owe my success to you and I wish the Chinese people nothing but the best and a life of prosperity for every single person.

[@piotrcurious1131]

actually without China it would happen everywhere else and as both Russia and China would not steal R&D and driving cold war measures You would probably not be a hobbyist but employed. The whole "new cold war" and property theft stalls entire industry. No GaN HEMT microprocessors for civilians. No neuromorphic and AI chips especially for computer vision (this is why your phone camera is still using tech from 90's and your "dog" robot or vacuum robot not having "mental terrain map" component) No SiC and SiGe semiconductors of any kind for civilians as this risks thermo imaging leaking to war zone. No CAD/CAM tools to design VLSI and ASICS for civilians. list goes on so yeah, in a way China keeps you being "hobbyist"... stuck with toys of 6yo...

[@Twitch_Moderator]

And filling the world with low quality LEDs. 😑

[@ashocatanouu9718]

@@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.

[@Ignisan_66]

This feels like chat gpt comment.

[@piotrcurious1131]

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.

[@Gersberms]

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.

[@Noobochok]

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).

[@Gersberms]

@@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.

[@Noobochok]

@@Gersberms most modern SMD somponents are good up to 260~ish for a minute, because the the lead-free paste used literally requires it for proper good joints. Still nothing to do with "longevity testing".

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??

[@Ledestar]

This is a tensile strength test.

[@starlite528]

To add to what @Ledestar said, it's for quality control. It's a destructive testing procedure performed on a random sample. Not all of them.

[@them0leisback]

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.

[@andychow5509]

@@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).

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.

In another KZbin 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.
