The purifier circuit board is based on the circuit schematic diagram to realize the functions required by the circuit designer. The design of the printed circuit board mainly refers to the layout design, and the layout of external connections needs to be considered. Optimized layout of internal electronic components. Layout all components of the circuit according to the functional unit. What are the principles of purifier circuit board design layout? The location of special components should generally follow the following principles when laying out:

　　1. The purifier circuit board should shorten the connection between high-frequency components as much as possible, and try to reduce their distribution parameters and electromagnetic interference with each other.

　　2. Some components or wires may have a high potential difference, and their distance should be increased to avoid accidental short circuit caused by discharge.

　　3. Components weighing more than 15G can be fixed with brackets and then welded. Those heavy and hot components should not be placed on the purifier circuit board, but should be placed on the bottom plate of the main chassis, and consider heat dissipation.

　　4. For the layout of adjustable components such as potentiometers, adjustable inductance coils, variable capacitors, and micro switches, the structural requirements of the entire board should be considered. Some frequently used switches should be used when the structure permits. Keep it within easy reach of your hands.

　　The purifier circuit board believes that the success of a product is to focus on the internal quality. The second is to take into account the overall beauty, both of which are relatively perfect boards, in order to become successful products.
