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.
