the power plane should be inside the PCB, and the upper and lower layers adjacent to him are 0V planes, and the distance between the two 0V flat faces should be at least 20 times the distance between them and the power plane.
Starting from the most basic PCB board, this paper discusses the function and design skills of PCB stacking in controlling EMI radiation.
Only under certain conditions can the 20H principle have obvious effects. 1. The power plane shall be located inside the PCB, and the upper and lower layers adjacent to it shall be 0V planes, and the distance between the two 0V planes shall be at least 20
When using power rails, high voltage components, and other heat sensitive parts of the board, the PCB line width in relation to the ammeter can be used to determine the line width to use in the layout.
In electronic product design, PCB layout and routing is an important step. The quality of PCB layout and routing will directly affect the performance of the circuit.
Multilayer PCBs are especially useful in the aerospace industry because of their small footprint and low weight.
Multilayer PCBs are circuit boards with three or more layers of copper foil. Compared to single-sided or double-sided PCBs, multi-layer PCBs are smaller and have higher assembly density. They are also lighter in weight because of the need for wiring harne
