How Chinese factories mass-produce LED lamp beads, interesting production process

[@GQ1494D]

I remember back in the early 2000's, a single 5mm blue LED cost over US$1.50 if bought in packs of 50 from electronics retailers, over US$2 each if bought individually. A 5mm or 3mm 7-color changing LED was about US$2.50 a pop, while 5mm white LEDs were US$2 each in packs of 50. UV LEDs were about the same price as the blue ones. Today, you can get any color LED you want for just a few cents a piece, and you don't even have to get them in bulk anymore.

[@miltonlai4850]

It's super cheap nowadays, it's literally 0.01~0.03 RMB(0.0015 ~ 0.004 USD) each in China.

[@BrilliantDesignOnline]

Fantastic! LED's are one of the most amazing, inspirational technologies developed, but even more amazing how long they last and how inexpensive they are. Thank you for this video and to the people who work making LED's.

Amazing video, this is why nobody can compete with the Chinese in manufacturing, everything is so efficient and quick, I loved seeing the led chiplets being spread apart on the blue tape when it was stretched so the machine can pick them individually, so simple yet very effective, more of these videos please.

中国有一个词，叫做”人口红利”，就是把人当作产业利益的一部份，底层人加班加点工作是普遍现象，不然就会面临失业的风险，这才是中国各行各业生产成本很低的原因，如果让欧美国家的人这样做，也许罢工抗议是必不可少的，然而中国人抗议的渠道都不被允许

@@BianChengKaiFa China's demographic dividend is no longer significant, and labor costs in Asia are relatively high. The advantage lies in China's strong education system and the complete ecosystem of the industrial chain, which contrasts with India. Despite having a larger population than China, India has not been able to develop these industries as effectively.

Well I’m gonna tell you the truth China did not invent that machinery that machinery comes from the United States of America and the company name is Alan Bradley they are the leaders in manufacturing processes. If you look at the machinery carefully it’s all written in English and then translate it into Mandarin I guess it’s the Chinese language so to be quite honest this would not be possible if it wasn’t for an American company making these machines so other countries can do it for a very very very very cheap labor that’s why it’s being made in China but it originally came from the United States of America and that’s the truth. To all my brothers and sisters to our Lord and Savior I ask you Jesus Christ of Nazareth is coming back and he’s going to be passing judgment we are living in the end times of the world so repent and ask forgiveness for your sins because our Lord and Savior Jesus Christ of Nazareth is coming back soon amen.✝️✝️✝️🙏🏻🇺🇸

[@sundog486]

Привет The mixing of the chemicals was for the phosphor that is coated on the LED chip for white LEDs. The LED chip emits blue light which excites the phosphor to emit broad spectrum light. A little blue light sometimes passes through to help balance the spectrum. The video showed a mix of different processes for coloured and for white LEDs.

[@tookitogo]

FYI, native English speakers never, _ever_ call them “beads” - that is strictly something Chinese translations use. We simply call them “LEDs”.

[@ytfanlingeric]

Your English vocabulary lesson in this video which focuses on the process and technology in manufacturing the "round shaped LED beads" (as opposed to the SMT type flat LEDs tabs/pieces?) is very impressive and much appreciated. Chinese translations should follow the US (western) rule-based nomenclature, despite the manufacturing process is the key of this video. And BTW, though not quite related to your lesson, if these LEDs are also to be sold outside of China, then by US nomenclature rule it is not "capacity to export" but "overcapacity".

[@tookitogo]

@@ytfanlingeric I understand the rationale, but in English, round-vs-flat isn’t the first level of the hierarchy by which LEDs are classified. First is THT/SMT. After that, THT gets classified by overall shape as it is viewed (round, square, etc). Then by the profile as seen from the side (dome (standard), flat, etc). Of course, anyone could figure this out by looking at how native English datasheets and catalogs describe them. Note that I did not say “US”, I said “native English speakers”, because this is not specific to USA, it’s how it’s used in ALL English speaking countries.

[@tookitogo]

@@ytfanlingeric As for overcapacity: ummm… no? Overcapacity means simply “when you can’t sell as much as you can make”. It says NOTHING about where you sell your product. Not that it made any sense for you to bring up this unrelated topic.

[@ytfanlingeric]

@@tookitogo Your understanding of "overcapacity" is what I understand, but the US Secretary of Treasury says otherwise and is accusing China of that for exporting EV cars, and Europe follows suit to hinder the otherwise good selling due to the great demand. That is, the US (western) has their rules of nomenclature for "overcapacity" among some other terms, and they are asking others to follow. I did specifically note that it was not related to your lesson. What came to mind was that some westerners think it is wrong for China to not follow their rules/terminology.

[@ytfanlingeric]

@@tookitogo As for round and flat shaped LEDs, the point I wanted to make was LEDs have different shapes, and did not intend to touch on LED technology. This is simply a video about the process of making LEDs, not one about language. Of course, you have your right and freedom to comment on others' English in non-language related videos. The point is whether it is necessary, and whether different expressions are tolerated. Having said that, this will depend on people so I am not going to debate on that. There were also Chinese viewers who picked on westerners' inaccurate pronunciation of "Chang'e" which is a Chinese lunar lander. I also pointed out to them that the video was about the "lunar landing", and not about pronunciation of the lander, so it is unnecessary to pick on westerners' pronunciation of a Chinese word, as so doing in that context was unnecessary.

[@Jace-yt2zm]

Enjoy your videos! One suggestion: It would be very helpful to include, all in the same caption box on the screen, the complete text for the explanation of each step in the process. It is difficult to follow when part of the previous explanation carries over later into the explanation caption of the next step. And also, to leave the caption on the screen long enough for it to be read by us slower readers.

Very interesting video. I'm surprised by how much manual handling there is. Keep in mind that 5mm LEDs are old tech. They have to be inserted manually into holes on the PCB, which is great for hobby projects but not so for industrial products. For those, you need surface-mounted (SMD) LEDs, which can be handled robotically at the circuit board factory.

I was surprised at how unclean the LED manufacturing process is. In the semiconductor manufacturing process, the process of attaching a case to the chip is called the post-process, but it needs to be done more cleanly. Products made in unclean factories like the one in this video often break down after a relatively short time.

[@PropellerSteve]

The LED is a fairly large and robust device, unlike a semiconductor chip which is super tiny and extremely delicate. These LEDs will last a long time if is used properly.

[@_DSch]

@@PropellerSteve Fake ws2812 leds tell otherwise. IIrc there was moisture/delamination which caused the whole LED to fail over a short time. The entire batch to be specific.

[@gabotron94]

@@_DSch Moisture can be absorbed into the epoxy, and during soldering, it can expand, cracking the epoxy and the wires along with it. I know this because I bought a spool of 1000 and lost nearly 50 to that... the solution is to first dry them slowly. This is actually true for most semiconductors.
