PCB Layout Design Introduction:
Layout design, in PCB, special components refer to the key components of the high-frequency part, the core components in the circuit, the components susceptible to interference, the high-voltage components, the high-heating components, and some heterosexual components. The location of these special components needs to be carefully Analysis, the layout of the belt should meet the requirements of circuit function and production needs. Improper placement of them can cause circuit compatibility issues, signal integrity issues, and lead to PCB design failures.
PCB size is the primary consideration when designing how to place special components. Kuaishou pointed out that when the size of the pcb is too large, the printed line will become longer, the impedance will increase, the anti-drying ability will decrease, and the cost will also increase; if it is too small, the heat dissipation is not good, and it is easy to interfere with adjacent circuits. After the PCB size is determined, the placement of special components is determined. Finally, according to the functional unit, all components of the circuit are laid out.
