Since the beginning of electronic design, circuit board manufacturers have produced multi-layer PCB circuit boards with various functions—all the way through. Every time the front is printed with silk screen, if there is a piece on the back; benefit:
1. When making PCB circuit board light board, because two layers are made less (if there is a piece on the back), the cost can be reduced.
2. Make the bare board surface of the PCB circuit board clean and tidy, avoiding the silk screen from affecting the welding quality.
3. To reduce the workload of hardware engineers, at least you don't need putpartname, and you don't need to make upper and lower silkscreen Gerber files.
Of course, if there is some information on the silk screen layer that must be expressed: such as the direction of the socket, the warning of high voltage danger, the label pasting box, etc. At this time, it is necessary to make the corresponding silk screen layer.
