Besides, the cost of production can be decreased. The author says this micro-miniaturization can lead itself to greater safety in another way. How do you think of it? Of course, it's true. In duplicate systems, for example, if one electronic device fails, a relay would automatically switch on a duplicate. But at the same time, the possibility of a failure is also decreased. But how? These micro-miniaturized devices have no bit of wire soldered here and there. There is no broken joints. But what if a fault does occur? How do you repair it? Using test equipment, of course. You locate the faulty circuit, then simply withdraw it, throw it away and plug in a new one. It's really wonderful.
