Since I was a child, I always wanted to see the manufacturing of LEDs, as an adult I can see it and it is incredible and comforting.

[@-PORK-CHOP-]

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.

[@BianChengKaiFa]

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

[@hassai100]

@@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.

[@TheStevenWhiting]

You mean "They use cheap labour, that's why no one can compete"

Astounding to think that only a generation or two ago China was still mostly poor and agricultural. Look at them now! 👍

Fantastic video, great to see the entire process! Still quite a few skilled hands needed during production.

[@ArnaudMEURET]

Not skilled at all. Those last few manual operations are so brainless it’s depressing. To think that the humans are there just because investing in a machine for this last gesture is even more costly than the labor…

Thanks for sharing knowledge! The process to manufacture our much-loved LEDs, which we use so much in our electronics projects, is truly incredible. Some of the process is manual, but a large percentage of the action is purely robotic.

[@thomastempe3301]

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.

[@MDV-YT-Samara]

Amazing China 🇨🇳 ❤❤

[@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.

Ein tolles Video !! Ich habe einige mal das Video gestoppt, um es mit Microschritten anzuschauen. So konnte ich einige meiner Kenntnisse verifizieren. Ich bin begeistert über die schnellen, feinmechanischen Abläufe, die wohlkoordiniert den nächsten Produktionsschritt mit einbeziehen. Verwundert beobachtete ich die drei Farben der LEDs, welche aber nur zwei Anschlüsse haben. Wie geht das ? Ich kenne durchaus RGB- LED, die hatten aber bisher vier Anschlüsse, für die drei Farben und Masse.

[@weitblick1206]

@@longlong686 Vielen Dank für die Antwort. Diese LED kann die Farbe nicht frei anzeigen. Eine Elektronik bestimmt die Farbe. Im Test bei der Produktion, haben alle 30 LED in die gleiche Farbe gewechselt, weil die Elektronikschalter ebenso gleich sind. Für eine Dekoration ist das bestimmt ein schöner Effekt. Ich verstehe, vielen Dank.

[@gabotron94]

You can file the sides off of a 5mm round led... it's all epoxy anyways, as long as you don't expose metal, you're fine. Did this actually once for a replacement I couldn't obtain.

[@ralanham76]

That intro is great

[@DogAndbeef]

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.

[@_DSch]

​@@gabotron94 yes i know, the issue was that they were failing like that after soldering them properly.

[@colormaker5070]

What the video did not show you is the quality and there 10-15% failure rate. Made in china you get what you pay for.

[@ytfanlingeric]

@@colormaker5070 The video shows you each of the LEDs are tested machine-electrically and examined machine-optically.

[@E_y_a_l]

@@ytfanlingeric Quality control and failure rate doesn't end by testing an LED one time, LED's suppose to last a minimum amount of use hours in some range of voltages and currents and that the machine doesn't test and we don't see quality control doing such tests for durability, I don't say they don't do them, just that we don't see them in the video so you can't use the machine lighting up the LEDs one time as a proof for a low failure rate, not saying anything about that specific factory, but generally speaking, China got their reputation for a reason.

[@ytfanlingeric]

@@E_y_a_l Have you actually used China LEDs and found 10-15% failure rate? I have yet to find a faulty one, or any one that ceased to work after long use. Do note that appropriate current limiting resistors are required in the LED circuit to prevent over-current. I do see some people's reputation for bad-mouthing, though.

[@E_y_a_l]

@@ytfanlingeric I use Chinese LEDs a lot, (with resistors...) and I don't remember too many faulty ones if at all from the type shown in the video, but that wasn't my point, my only point was that you can't say they have a good quality control procedure just from that single lighting test we see in the video since the demand from these LEDs is not only to be light up once, and again, I'm not saying anything about the failure rate of the specific company in the video since I have no data to suggest they have a high failure rate, what we're talking about here is the Chinese reputation of mass production in general, but also, specifically about the company in the video, the ovens and resin containers look extremely worn-out and dirty, and that's when they knew they were going to be filmed, so maybe the LEDs will work, but I won't be surprised if the clear container might have some dirt in some of the LEDs.
