Multilayer PCB design method (M)

The above is the general principles of the PCB layout and wiring, but in practice, the layout of the components and wiring is still a very flexible work, the layout and the connections of the components is not the only way, the result of the layout to a large extent depends on the designer's experience and thoughts. In a manner of speaking, there is no a standard to judge the layout and wiring scheme of right and wrong, and can only compare relatively better. So the above layout and wiring principle as a design reference only, the practice is the only standard of judgment.
11.2.3 The special requirements of multilayer PCB layout and wiring
Compared with the simple single plate and double board, multilayer PCB layout and wiring has its unique requirements. For multilayer PCB layout, sum up is to arrange the different power supply and the layout of the types of components. Its purpose is to bring electricity in the back of the segmentation is convenient, but also can effectively improve the anti-interference ability of between components.
The so-called reasonable arrangement of the power supply and to the layout of the type of components, is to use the same power level and the same type of components together as far as possible. For example, when a + on circuit principle diagram, + 5 V, 3.3 V? 5 v, + 15 v,? 15 v, voltage grade, the designer should use the same voltage grade of components placed centrally in the circuit board of a certain area.
