    Xiaomi said assembling a smartphone from circuit board to finished product takes about six seconds, and, at full capacity, the factory could produce more than 10 million devices annually

    There are ~30 million seconds in a year. So this factory is only producing 2 phones at a time? Assuming the article is accurate, I’m very curious to hear why this was chosen as a design

      Especially since it says 11 production lines…

      11 lines = 57.8 million

      57.8/~10 means their lines are down 38.5% of the time?!?!?

      Edit: Maybe the nearly 40% downtime is retooling for different models?

        The rule of thumb is to plan for machines having 80% uptime. Mind you, new lines, and especially new technologies are often a clusterfuck until they mature and you really understand the quirks of trying to do what you’re trying to do with them. But yeah 20% retooling would make sense if they have a lot of models and a really complicated retooling process, but if that’s the case, well listen, I believe it, but I’d be asking questions about how to cut the tool change time down.
