      Wrong. It is currently cheaper in the short to medium term to continue to use humans instead of investing in research to create a machine to do the job.

      A better example than motherboards is clothing. Take T-shirts for example. The textiles industry was historically the first to become industrialized, yet here we are 250+ years later, and there are still people in sweatshops making the simplest items of clothing. Why? Because it's technically too difficult to automate clothing manufacture? Whatever.

      The reality is that no motherboard, clothing, or any other company is willing to actually spend money and innovate. Find ways of making basic items by the millions, quickly, reliably, cheaply. And the reason they're not willing to do it is because they can still find cheaper and cheaper sources of labour. On China, they're current strategy when wages on the east coast get too expensive, is just to move 100km inland, rinse and repeat.

      There is lack of innovation in the manufacturing sector. It's caused an oversupply of cheap labour. Simply put, there is no pressure on factory owners to continue the industrial revolution, and human progress. Instead there's an incentive to use quasi, and what the hell, full blown slave labour.

      I harp on China, but it's happening all over. It's happening a lot closer to home than you think. Our society is back-peddling, and it's down to the fact that rabid (no so)free market capitalism has become the dominant ethos of our politics and media, where it is assumed that no matter what the issue problem or injustice is, the omnipresent "market" will find a solution to all our ills.

      I'm not some fanatical anti-globalisation, anti-capitalism protester. I just think that too much power, not money, power, is being concentrated into the hands of private companies.

      Bleeding-heart westerners often this ridiculous notion that workers should be treated well everywhere in the world. This is an idealism that does more harm than good. It is far preferable to have 100 workers working for a barely livable wage than to have 20 workers working for a fair wage. The simple fact is that the cost of progress is high, but the cost of allowing progress to pass you by is even higher. Consider the textile industry in a place like Bangladesh (where my parents are from). Most westerners would look at the working conditions in these places and be appalled. Yet, most Bengalis will tell you that the textile industry has been on the whole good for the country. It has employed women who would otherwise be toiling away in rural areas for no pay at all. It brings them into urbanized areas, which as filthy as they are, are still preferable to the rural backwaters which they left behind. It brings them closer to clinics and schools, however poor they are, wheras before they would've had no access to these services at all.

      Westerners remember with horror the days when their own cities were like this, and feel that allowing such conditions to exist in the modern world is not acceptable. But the world is not modern for everybody. While it's 2007 for people in the US and Europe, it's 1920 for people in places like Bangladesh. There is no alternative for these societies but to deal with the price of progress, in the hopes that one day they can enter the modern world. If they are successful in this endeavor, then decades from now they too can have the luxury of being able to turn down work just because the conditions are below standard.

      First, it's not a bad thing to provide employment for people. You might recall the auto unions terrified that robots would replace workers. So using people to assemble things is not a bad thing.

      It's actually pretty difficult to make an automated machine that can assemble parts. Some of the ones we have cost nearly $1 million. At that price, we can only afford to use them where the product doesn't change, and/or there are serious hazards to having a human do the job.

      Since motherboards change a lot, using automated equipment would add delays, increase capital expense, and require a highly skilled team to keep them running. If you put 20 robots in a continuous line, a failure of one shuts down the line. If you only get 3 failures per year per robot, your line is down 60 times per year. You can retrain humans quickly, and they adapt quickly to design changes. Humans are a good thing...

    When he says "The adhesive needs to be hardened, so the components won't fall off" he means the solder paste is melted then allowed to cool with the components in it, thereby attaching the components to the PCB electrically and mechanically.

    When he says "BIOS Taping Area, I'm not quite sure what went on here" I would guess they are writing the BIOS code into the flash memory.

    As he doesn't really explain, the reason people are putting connectors on the board manually even after the automated component placement stage is because the plastic connectors would melt in the heat of the oven, before the solder melted. So there are two processes: first the small, high tech chips are put on and soldered in the oven, then people manually insert the funny-shaped easy to melt parts, and they are soldered separately.

      Lets see if I can shed some light on this process. First off I'm an ex process Eng. that worked in a contract SMT manufacturing facility here in the US before every thing moved offshore. Actually started at Compaq the Motorola then did a stint with a little contract house then moved on to one of the big contractors. So what all this means is I know what I'm talking about.

      1) The above poster is correct in that the first pic we have is a Screen printer. It's function is to apply solder paste to the PCB. The machine next to it in the same pic is a laser and vision solder inspection station. It's job is to make sure the screen print is good. It checks both the hight, registration and coverage of the past. Approximately 90% of all defects in a good SMT manufacturing process are cause at this point due to clogged solder stencils so in high volume shops you put a solder past inspection system in place to catch those errors while it is very easy to recover from them. You just wash the PCB and run it again plus clean the stencil before you have to many bad boards.

      2) The next machine he takes a picture of is a Pick and Place machine which means he missed one. The actual next step after solder inspection is the chipshooter and as the name implies its job is to place the passive components on the board. When I left the business about 5 years ago the current state of the art was able to place about 10 components per second. This machine is basically a big gattling(sp) gun type of design. In that the placement heads rotate around a turret and the board moves (That is why you can only place small devices with it). After the chips are placed we normally also placed the smaller IC's with the chipshooter as well. You just have to slow it down to do that part or the IC's will slide off the board as it moves (it moves very fast normally about 12 inches per second and from dead stop to full velocity in under .01 sec's).

      3) Now comes the pick and place machine that he did take a picture of. It's purpose is to place the larger components on the board. In this machine the placement head moves not the board. All components are both vision tested(leg bend left right test) and laser (for leg flatness or bend up down tested) before the component is placed on the board. Depending on the part and the number of heads on the machine the pick and place can place parts on the board at about the 4 per second range. Larger parts take longer mostly due to there size and or weight. Basically if you move the head to fast the part will fall off or become missaligned.

      4) The next machine he takes a pic of he got right it what it does. It visually checks to make sure all of the parts are on the board. It will also check alignment and if the part has some distinctive feature it will make sure it is the right part as well.

      5) The next picture is the reflow oven. It is basically a big convection oven the better ones are forced air ovens. The problem with his description is that he states that it heats the board up to 200c which is not correct it gets a little hotter than that. How hot you have to heat the board and components depends on the solder past and the components you are using. Now that most SMT manufacturing has moved to lead free paste it is mostlikly getting closer to 250c.

      6) Visual inspection. Yes this is still done by humans. There are many issues with doing this by machine at this point that are not easy to solve. You can machine check components but we already did that before we put the board in the oven so why do that again. What the girls are looking at are the solder joints mostly. If the oven has lost a zone or the air flow is not right for some reason then the solder joints will change in color and how it looks. Again this is a very hard problem to solve with a machine because it is hard to see fillets and hills (the solder wick up the side of a component) with a camera no matter how high of a resolution you have because to see it you have to have light and the light will cause brigh

The problem seems to be that when someone mentions manual labor done in Asia people automatically assume people are being exploited. I agree it's a serious issue in China. However, this hasn't been the case in Taiwan for decades now. There are numerous laws in Taiwan protecting workers and they are enforced.

    And in my experience they are very industrious workers. I've heard surveys quotes that Americans are among the most productive works in the World. They work hard, but honestly, I don't believe it. Either other nations don't bother doing adequate surveys or American companies inflate productivity. I did also hear another survey that said American workers were complainers, the French and British are worse. I believe that too. Taiwanese are much like the Japanese. There's a job to be done, they get in there and do it. And they do it quickly. They have an excellent work ethic, and take any job they do seriously. It's why you can walk into a Starbucks or McDonalds in Taiwan and the place is spotless and service excellent.

Unlike American companies where we get stuck with business and marketing idiots making important decisions. I can't count the times I've had to deal with guys here who don't know what they're talking about and end up making fools of themselves in meetings. Even worse, they don't care to learn because they think it's all beneath them. So they end up managing based on emotion, almost like children.

    Not that there aren't problems there. I think Taiwanese in general are underpaid. And there's this ideal there too many people have that once you're in management you basically get to screw around all day. Some managers, especially in office environments, can get verbally abusive with employees. It's the sort of thing that no way in hell would ever fly in the US.

    Anyway, I had the opportunity while working there to visit a few companies, and I got to see some cool stuff. Like I said, it's mostly manual labor. I was disappointed when I first saw that; I was hoping to see these giant robotic arms swinging around, going about their business. But it's not the case. It would just be too expensive to purchase and then set up this equipment. And then having to retool for other products would be another hassle.

    I also did some work for a company that sold and installed semi-conductor manufacturing equipment. That was one business where companies didn't want employees directly handling the product. So business was good for this company.

    Taiwan has two of the largest contract semi-conductor foundries in the world. Now that was impressive. The company I visited a few years ago had just recently completed this new facility in southern Taiwan. This was when companies were first starting to move over to 300mm wafers. So they installed this transport in the ceiling to transport these wafers around from machine to machine. The wafers are carried in this case which is something like 1.5ft all around. It has handles so it could be carried. And people did used to carry them around. But given that a case full of at least 10 wafers can be worth hundreds of thousands if not millions of dollars they decided they didn't want to risk having people drop these. Hence the transport system. In fact, the facility had relatively few people there, most were responsible for ensuring everything was running properly or setting up new equipment. All in all, it was impressive.
