Very interesting and complete. The only thing they missed was the fluxing of the boards before the wave-soldering process. BTW, my friend in the taximeter shop has a mini assembly setup. Just loading thru-hole parts on premade boards and flow-soldering, but nonetheless similar in principle. We're thinking of setting up an SMD line if we get enough volume to justify it. You can get pick and place machines for ~$20K on eBay, and a reflow oven for about $5K. Smaller than in Gigabyte's factory of course, but enough to make what we need.
