Watching this video in the morning, What an amazing meditation!

[@movax20h]

Really cool. A lot of older machines and techniques, but still looks very organized and efficient.

[@Crazydance506]

thank you.

[@acme.videos]

Excellent factory workers!!😊👏👍

[@RalphRacc00N]

yea but the guy @ 10:06 over torqueing and destroying the threads of that fastener.

[@valerius39]

Old SMT machines from the 90' but still gets the job done.

[@hugoromeyn4582]

Evidence that China is able to produce very high quality products!

[@wardfiction5693]

Its amazing how much work goes into making something like this, it may not look much from the outside, but take off the cover, and a world of wonders is inside. But the hard work people, (No matter what country is was made in) have to do to make something like this... . I originally thought the PCB boards were compleatly done by computers and machines, even assembly...The way these things are made is simply amazing.. But no..Then at the end of its use, it gets discarded or thrown in landfill.

[@Andrew-rc3vh]

Amps like that have a lot of large components which are wire-ended. If you did a low power circuit like a computer board you could possibly manage nearly all SMD. I understand most of the work then is setting the machine up for a production run.

[@manusudha4269]

As an amplifier designer , I can understand you so well.

[@markianclark9645]

wardfiction..."Then at the end of its use, it gets discarded or thrown in landfill" OR it ends up like on eBay and people like me collectors and hoarders bid and buy the retro tech and fill up our storage with these seperates...i even swap and change them out to let other Amplifiers and Cassette decks have a turn

[@Ed5on]

Vida longa a China por nos proporcionar tecnologias a preço justo, aqui no Brasil só temos lixo, mas graças ao Paraguai conseguimos esses amplificadores, hoje meu som é todo com amplificadores Chineses, e o governo aqui do Brasil que chore por que não dou um centavo a produtos Brasileiros muito menos imposto de 100%

Непривычно смотреть что все сотрудники без униформы, у всех произвольная одежда. А это показывает культуру пооизводства

[@XYZ736-hdr]

надо учесть, что ещё 30-40 лет назад весь Китай занимался только выращиванием риса и чая, а теперь они снабжают весь мир своей продукцией, качество продукции - разное, но уровень некоторых технологий достаточно высокий. Особенно интересно сочетание нескольких технологических эпох на одном предприятии.

[@chaddentandt9868]

The stuffing machine and it's speed, accuracy, and scanning of parts is absolutely awesome.

[@tookitogo]

And it’s not particularly fast. Those are, according to other commenters, 30 year old pick and place (SMD) machines. Newer machines, especially used with smaller components, are way, way faster. As for the through-hole components, that speed had already been achieved by the 1970s at the latest.

[@StealthGT40]

@@tookitogo yeah but the old smt machines are for older components ie the Fat capacitors the newer one are designed for miniature components

[@tookitogo]

@@StealthGT40 Every SMD pick and place machine will be slower with large components than with small ones. Nonetheless, modern PNP machines are FAR faster than the ones shown here, for any given component. The fact that we often use smaller components now only adds to the final placing speed.

[@Andrew-rc3vh]

@@tookitogo There is a serious g-force with a fast machine. I think you need to bolt the thing down, like far worse than poorly loaded washing machine!

[@tookitogo]

@@Andrew-rc3vh That‘s an interesting question! Bolting or weighing down is one way, but another would be some kind of counterweight system. As long as the forces cancel each other out, it‘ll theoretically be stable. (Industrial washers, and a handful of very high end domestic models, do active load balancing by pumping water in and out of chambers built into the wash basket to exactly balance the laundry itself. The domestic models have only had this for maybe a decade, but in the industrial models it’s been around since at least the 1980s, possibly much longer.)

[@Sixta16]

Likely a design copy from a LAB GRUPPEN, which is a well known western brand. This Chinese brand appears to have even partly stolen the name: LAB GREEN. Watch closely in the video, you can spot it on multiple occasions. If you look for LAB GRUPPEN FP10000Q, you can easily spot they've even copied the internal design to a high degree.

you start making analog amps by hand, with toroidal psu, no smd components inside, you just need to find very good schematic and it will probably work longer than you will be alive.

[@galaxieman1000]

Great video but to complete the story would be a video on the machines they used being manufactured.

[@valerius39]

They have a semiautomatic printer using stencils with squeegee rolling paste into the apertures , than next process is SMD components placed by old SMT machines Fuji model CP, than they go trough reflow machine to liquefy the solder paste and than turn it into solid cositor joint uniting pcb pad with component, than I see use a old Panasonic PTH machine to introduce into PCB the trough hole components than place manually into a wave soldering machine that has molten cositor touching underside of pcb, the terminal of the components to fuse it with the pcb , after that they have a inspection machine or AOI that has predefined program that checks presence of components , misalign and check for other manufacturing defects probably, than they test the finish product :)

[@JohnDoe-es5xh]

They forgot to populate 4 big electronlytic capacitors. 😞

[@abc-ni9uw]

I noticed that too 😊

[@mxslick50]

Depends on the amp's output power ratings,. this is probably one size down from the largest amps they make. QSC "Powerlite" designs all use the same mainboard, but it is populated with only the necessary caps for the power rating. Saves a LOT of money in manufacturing, requiring only ONE (or a few) PC boards to cover a whole range of amps.

[@InTimeTraveller]

Why isn't anyone in this company wearing ESD protective equipment and/or gloves?? I've worked in a PCB factory like this as a test engineer, if I went in the factory floor without ESD shoes, jacket and gloves, they would have my head! You cannot ensure quality without ESD protection that prevents damage to the device and without workers who handle hundreds of boards per day wearing gloves because you might leave fingerprints on the product (for certain ultra sensitive applications the fingerprints might actually affect performance, but it's mostly to ensure general cleanliness).

[@arbjful]

Those are passive components. Also these plants have ESD and dust filtration at the entrances

[@KuntalGhosh]

first of all these are dirt cheap amps , they are made be loud not be high fidelity and there is no components used in a class d amp that is esd sensitive . all of the parts can take kv's of esd without failure.

[@marcocevat672]

That is why production in China is so cheap. Safety of people doesn't matter, so why spend the money on it. I have seen videos of a chemical plant that had similar working conditions, so this one isn't even that bad.

What do you like about this power supply and how do you know that "they are working very good and priciesly.", if you ask how to get one of them it means you doesnt have this amp for at least few years, so you know nothing about it.

[@RasanSamarasinghe]

What is that vibration test done in the process?

[@Kelvinbrook_101]

I guess... It's necessary bcs incase of any particle or tiny object/residue in the chassis assembly might be a thread to the system doing so to avoid short circuit making sure everything is tied in place.💯
