What principles should PCB special component layout follow?
Due to the design requirements of PCB, it is often necessary to arrange some special components on the pcb board, such as large components, heavy components, heating components, transformers, ICs, etc. Once the layout is not good, the PCB will have serious quality problems, leading to the scrapping of the whole PCB. So, what principles should PCB special component layout follow?
PCB special components
1. For some components or wires with high potential difference, the distance between them shall be increased to avoid accidental short circuit caused by component discharge. High voltage components should be kept out of reach.
2. The connection between high-frequency components shall be shortened as much as possible, and their distribution parameters and mutual electromagnetic interference shall be reduced. Components susceptible to interference shall be kept as far away as possible.

3. Components weighing more than 15G can be fixed with brackets and then welded. The heavy and hot components should not be placed on the board, but on the bottom plate of the main box, and the heat dissipation should be fully considered. Thermal components shall be kept away from heating components as far as possible.
4. For the layout of adjustable components such as potentiometer, adjustable inductance coil, variable capacitor and microswitch, the structural requirements of the whole board shall be considered; The frequently used switch components should be placed in the place where the hands can easily touch if the structure allows.
In a word, components should be arranged in a balanced manner, and should not be top heavy. The success of a product should focus on its internal quality. Second, we should give consideration to the overall beauty. The perfect boards of both are the successful PCB products.
