You clearly have absolutely no clue how automated SMD soldering or pick'n'place tech works and how fast it can do things. It's the exact same machine assembling both Chinese and "western" products. At best it will take ~30 seconds per PCB, depending on size and capacity of the placing machine. Which is absolutely insane considering amount of components and complexity of modern smartphones.

I'm not bashing the tech, I'm bashing the journalist reporting on it.
