Pcb general component layout
According to the functional unit of the circuit, when laying out all the components of the pcb, the following principles must be met:
1. Arrange the position of each functional pcb unit according to the flow of the circuit, so that the layout facilitates signal circulation and keeps the signal as consistent as possible.
2. Center around the core components of each functional pcb and arrange it around it. Components should be evenly, neatly and compactly arranged on the PCB to minimize and shorten leads and connections between components.
3. PCB operating at high frequencies, taking into account the distribution parameters between components. Generally, the circuit should be arranged in parallel as much as possible, so that it is not only beautiful, but also easy to load and weld, and easy to mass-produce.
4 The pcb components located at the edge of the board are generally not less than 2mm from the edge of the board. The optimal shape of the board is a rectangle. The aspect ratio is 3:2 or 4:3. When the board surface size is larger than 200mm × 150mm, the mechanical strength of the pcb board should be considered.
