it justs tiks my off

[enliteneer]

Does the solder-wave machine use heat? For example, if the PCB has surface parts on the bottom side as well, wouldn't the wave affect those components' solder?

Also, in the first tour, since the pick and place machine does not include any solder, do the parts ever shift or move slightly as it's moved to the reflow oven? How is the temperature profile determined?

Good tour but looks like

5:43 20 hours a day work for 10 Yen a week.

8:02 The girl, she looks about 10 Yeras old.

@Films4You that what happens if you're a student in China, if you make a single mistake, you will go to a sweat shop (eg. Nike, PCB assembly,& plastic poduct facotries)

[williefleete]

[averagemale2000]

I said it once, I'll say it again,,,,, freaking cool tour!!! Thanks Dave.

Hey Dave, one question. At 7:44 where there's an "automatic bed nail", what's it's correct name?

I think I misunderstood the name.

And also, what's its job?

[jjjperrin]

@migsantiago this was a long time ago, but if you are still curious it's called a "bed of nails" because it has tons of test pins that check all the traces and connections.

[TypeTuber]

I'm surprised they let you film openly in there, any factory I've toured it was only approved pictures.

Enjoying all your videos!

[lundyoutu]

Awesome video. I loved it.

Please keep the videos coming!

You need to work on your delivery and mannerisms. Listening to you speak was extremely annoying.

I apologize for saying this.

[pytey]

lundyoutu: That is really quite rude. This chap isn't a TV presenter, he is a passionate, Australian engineer, with the mannerisms and accent to match.

If you haven't got something nice to say, don't say it at all, if you don't like it, don't watch.

[liquidvideotube]

hahah your killing me.. yeah it is annoying but I dont care.. The dude is great and his blogs have really made me excited about my degree.. Although if Screech from "Saved by the bell" grew up this is him LOL... Any I love the dude he is rockn doing a great job

[shodanxx]

@lundyoutu

that is constructive criticism if I ever heard it

I suspect that you are not a native english speaker and that his accent makes it hard to understand (I assume that on your slightly contradictory wording of "extremely annoying" and then appologizing, because you probably meant "difficult to understand" which is less emm, inflamatory)

btw I am not a native english speaker so I understand what you say although it doesn't affect me anymore and I now think this is part of why this blog

[shodanxx]

@lundyoutu (continued) is so great

and @pytey

"If you haven't got something nice to say, don't say it at all"

this is extremely bad advice to give and bad for you to say

first it discourage negative constructive comments

this is called shooting the messenger

and second by saying that you are preventing potentially valuable information from reaching you, it's a double whammy of bad management and it is an extremely common mistake that even I do sometimes

it's never pleasant to hear that but

[Anothercoilgun]

Good video and channel.

[kchididdy]

very cool!! thanks for sharing. those pick and place machines are fast. i bet there are others out there that are even faster. mind-boggling.

[Twistx77]

I always wanted to see that! Thank You so much!!
