PCB circuit boards use insulating boards as the base material to replace the chassis of the previous electronic components. With the rapid development of the electronics industry, PCB circuit boards are now developing better in the electronic field.
The basic rules of PCB circuit board layout
1. The position of the clock PCB circuit should arrange reasonably.
2. Since the distribution parameters of circuit components under high-frequency working conditions must be controlled within a specific range, all components should be neatly and evenly distributed on the double-sided circuit board to reduce the lead length between components as much as possible.
3. A certain distance should be kept between the digital and analog circuits, mainly to avoid the interference of the digital signal on the analog signal.
Before the advent of PCB circuit boards, the interconnection between electronic components was almost a circuit formed by the direct connection of wires. Nowadays, circuit breadboards are only used as an experimental tool, and PCB circuit boards have already occupied a place in the electronic field.
The parts and wires are distributed on one side of the primary PCB. Because the cables appear on one side, it is called a single-sided board. Because the single-sided board has stringent restrictions in circuit design, the early circuits use PCB board.
