PCB layout process, the system layout is completed, to review the PCB diagram, system layout is reasonable, whether it can achieve optimal effect. Usually can be investigated from the following aspects:

1 whether the system PCB layout is reasonable or not, whether it can guarantee the reliability of the wiring, whether it can guarantee the reliability of the PCB circuit. In the layout of the need for the direction of the signal as well as power and ground networks have a whole understanding and planning.

2 printed circuit board size is consistent with the size of the processing drawings, can meet the requirements of PCB manufacturing process, there is no behavioral markers. This requires special attention, a lot of circuit layout PCB board and wiring are beautifully designed, reasonable, but neglect the precise positioning of the connectors,

3 frequently changing PCB components can be easily replaced, whether the device is convenient. The convenient and reliable replacement and replacement of PCB components should be ensured.

4 adjust the adjustable PCB component is convenient.

5 whether there is a proper distance between the heat sensitive element and the heating element.

6 in the need to heat the place is equipped with a radiator or fan, air flow is unobstructed. Attention should be paid to the cooling of PCBA components and circuit boards.

7 signal direction is smooth and the shortest interconnection.

8 plugs, sockets and mechanical design is contradictory.

9 whether the interference of the line has been considered.

10 the mechanical strength and performance of the circuit board is considered.

11 circuit board layout of artistic and aesthetic.
