Critics argue that reliance on mass production machines in LED chip manufacturing may compromise quality and lead to inconsistencies in performance.

Central Asia: where the future looks bleak and the present isn't much better.

You can't really see the brand, and it's not hidden because it's a secret, it's hidden because they don't want to advertise the brand for free

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.

**((secret information they dont want yuo to know))**

Heard Central Asia's education system is a joke - they're still teaching lessons from the last century.

@@cleitonfelipe2092 I can quite clearly read XYMD on the ovens. It's just funny how they blur it and then forget later on.

And filling the world with low quality LEDs. 😑

@@asmongoldsmouth9839 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.

This feels like chat gpt comment.

machines make machines... humans are not needed anymore

They pay huge amounts of money to genius people. Can be in Engineering, Biomechanics, etc. Then those people do computations and tests.

Yup. Makes huge difference.

Proponents highlight the scalability afforded by mass production machines, allowing for high-volume output to meet growing global demand for LED technology.

The resin also contains a fluorescent powder that converts blue light into a regular combination of white light.

Concerns arise over the environmental impact of mass production machines used in LED chip manufacturing, particularly regarding energy consumption and waste generation.

The use of mass production machines in LED chip manufacturing underscores the need for rigorous quality control measures to ensure product reliability and longevity.

It looked so strange to me as well. If something, the hands are a real source of contamination...

food industry machines

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

Maybe having uninhibited manual dexterity is more important to a stable production line🤷🏼‍♂️

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.

@@starlite528 Are they expanded? and do they stay expanded?

This is a tensile strength test.

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.

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.

They don't have sunlight and only grow under the illumination of LEDs

台湾有什么品牌的led？我都没听说过。

Yes, this doesn’t look like a production line but more like an assembly line.

Advocates emphasize the role of mass production machines in accelerating technological innovation and advancing the capabilities of LED chips.

Not true!

It's a very good working space in Chinese manufacturing already. Manufacturing gets less and less viable in the US and Europe for a reason.

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.

@@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".

food industry machines

Step into Central Asia and prepare to be amazed by their lack of progress - or lack thereof.

i think its phosphors to convert ultraviolet and bleu radiation to white .

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.

Central Asia: where the air is thick with pollution and the land is scarred by neglect.

Luminophore gel

No need to wear gloves to produce LED. They are not producing advance Semiconductor Chips which requires to wear gloves.

Critics caution against overreliance on mass production machines, warning of potential job displacement and socioeconomic implications for workers in the LED manufacturing sector.

It’s not impossible as long as it’s being worked on

It's a test of adhesion strength, which is only possible by destroying it.
