Layout of circuit board components(2)

According to the principle of circuit functional unit layout of the umbrella components of the circuit:

(1) Each functional circuit should determine the corresponding position according to the flow direction of the signals between them, so as to make the wiring convenient;

(2) Each functional circuit should first determine the position of the core element, and place other elements around the core element, so as to shorten the connection between the components as far as possible;

(3) For high frequency circuits, the distribution parameters between components should be considered;

(4) The components placed on the edge of the circuit board should be not less than 2mm from the edge of the circuit board;

DC / DC converters, switches and rectifiers should be placed as close as possible to the transformer to reduce external radiation. Voltage regulating elements and filter capacitors should be placed close to the rectifier diode.
