Supplement: The company mainly produces pins and various connecting devices. There are thousands of people there, most of them make this kind of thing, and some of them are machined, but they are all equipped with pins. Single chip microcomputer technology is almost useless there. The company pays well, and ordinary workers can get 2000. However, this is achieved through overtime and extended working hours. According to what you have learned, it is estimated that it will not last long, because it is not quite right. For people with goals, they won't go into that stupid company to do the work done by robots at all. Besides, I don't know whether you studied protel99se or protel DXP2004. thank you
