Yamaha makes an outstanding solder printer. Displaying pressure in (force/squeegee length) is unique but correct. Having an adjustable squeegee angle can be very useful with certain solder pastes. I haven't used their P&P but am told they are also outstanding.
BTU ovens are best in class, but that software looks significantly different than my North American Pyramax. They may have different SW development in different regions.
Your reflow oven and process explanations are a bit rudimentary, but I assume that's partly Chinese to English and partly skilled worker to tour group translations.
If you ever want a fully technical explanation, I would be happy to do a video call and go through the whole thing in full detail (metallurgy, solder paste as a material, the reflow process, various defects that can occur). I can't offer a tour of my job because it isn't as exciting as high volume/low mix and is high security.

Honestly I'm always a bit surprised to see standard PCs being used for component burn-in, it seems very labor intensive to me. Especially with something like DRAM where you don't need a complicated driver stack (like for GPU testing) - I'm surprised they don't have dedicated burn-in systems built using FPGAs. Maybe low-end COTS PCs are just so cheap it wouldn't pay off and it's cheaper to just have a roomful of PCs instead. Plus perhaps the marketing advantage (though I've never seen it) of burned in on an actual COTS PC - worked for us (tm) .

15:25 it almost looked like you started loosing voice or may be cought up cold , if it was that long to record for this video, hope you are doing good just somethign i notices it was different at the end, anyway i am digressing, what a journey, not because of a factory tour but the way / vision you put into the script/narration/story telling. Both the case manuf video and this one are just very differently tuned from other videos but actually resebmbles more like the HWNews type of feeling. Very excited for next ones... good luck!!!

Wait a minute.... i didnt know that yamaha is make a machine for electronic assembly line. Holy F !
Also, do peoples in this assembly factory used an ESD strap ? Or they didnt really worry about ESD since TW has a high humidity/almost all process is automated ?
I always thought that V-colour is a 2nd grade brand, I'm so fcking wrong x.x
Guess now i have to think that none of the brand is a 2nd class brand.... Its just the Costumer services that differentiate them.

Thank you for real for this amazing tech journalism you do. It's realy important for a lot of people to be able to see how things are realy made at the source, and there is less and less places we can actualy see it. it's very important that some real journalism is still being made for the tech scene. You do a great value for the community and you should be proud of it. Thank you again.

I wasn't expecting their burn-in tests to just be done on a rack of test benches made from off-the-shelf components, that was really interesting to see. I imagined they'd have a bespoke, purpose-built machine to test their memory. It makes more sense to use normal mobos and CPUs, though, since that's where they're going to ultimately end up and you'd want to test for real-world usage.

I mentioned this last week, but the post-production is absolutely top notch. Did GN hire a composer for the music, or was it all royalty-free music? Because if it's royalty-free music, I have no earthly idea how your editor is able to sync the b-roll of the machines to the beat of the song, so I can only imagine that he would have to be some kind of wizard or warlock.

I'm kinda confused about the thumbnail saying you binned your own ram and seeing your logo on those 2? Sticks. Is that something they surprised you with?
Either way what a cool video and series. I always look forward to them and a big thanks to all the companies that allow this to happen. And of course major props to the GN team for well done videos!

Those are expensive as stingrays if they be freshwater polka........ like thousands to tens of thousand with some selling around 100k usd at the very top. 0:44. There was a multiple stingrays, congrats on that level of success XD they also may be Thousand Island Black Diamond Stingrays which are 600-700 a 6 inch stingray

Nice to see other SMT lines at work. At my workplace we have 2 SMT lines, I'm in charge to mount reels on feeders for the SMT tables, checking for any errors on the setup and sometimes supervising the lines. It's real fun when you receive parts in tubes instead of reels... Placing them by hand is a real pleasure x)

I work with SMD pick&place machines - and everything before and after those... Indeed, they are very cool and will beep at you mercilessly. Shame you didn't get to film the AIO part, would've been cool to see that.
Also, whoever said Windows XP is dead... Glad to see others struggling with it too still lol.

this is very cool! ive always thought if actually making my own computer as soldering maybe a kb of ram on pcb and on a bread board and such and maybe something like an intel 4004(or some processor of the sought) i just dont have the knowledge. definitely something to think about though!

At work we were buying some cheap v-color sticks to keep ddr4 in stock a few years ago. They all worked great. DDR4 prices came down though and I'm getting them from my refurbisher and ebay now. Hey, I want a special RAM riser to diagnose ram with, that would be SWEET

Extremely interesting, thanks Steve and team!
A legal factory in a mixed use building with residential? VERY interesting... Well, it doesn't sound like a jet engine or use dangerous chemicals or anything so it doesn't sound TOO Middle of the industrial revolution ...

Interesting video and great production!
Perhaps my expectations were just off, but I kept waiting for more technical detail on what each stage was doing, e.g. what sort of tests were the binning robots running, what were the pass/fail criteria, etc.

Every time I use the soldering/project matt I am impressed with how nice it is. From replacing a friend's laptop battery (which involved pretty much taking it completely apart) to some fiddley plumbing stuff I did recently, it's just soo good.

03:19 : is that windows XP , why do industries always get the best to use and consumers get windows 11 and shit like that i mean after windows 7 i cannot see myself convinced at any point that increment in number is better OS , just jealous now

8:50 to be super pedantic, the solder mask you're referring to is actually the solder stencil. Solder mask usually refers to the non conductive coating on the PCB itself (the stuff that's usually green, or in this case, black).

Ok but i still am not sure how ram gets from the factory to the internet and then into my computer?
i told gary from nepal that i already gave him the apple gift card codes but he hasn t gotten back to me yet on my 256mb of ram
