so as not to cause reflection interference. If necessary, the ground wire should be added for isolation.
The wiring of two adjacent layers should be perpendicular to each other.
Parallel simply creates parasitic coupling.<\/li>\n<\/ol>\n\n\n\n\n
Widen the width of power supply and ground wire as far as possible,
Most preferably, the ground wire is wider than the power wire,
Their relationship is: ground wire>power wire>signal wire,
Usually the signal line width is: 0.2~0.3mm, the most thinner width can reach 0.05~0.07mm,
The power line is 1.2~2.5mm\n\n

The frequency of the digital circuit is high, and the sensitivity of the analog circuit is strong.
For the signal line, the high-frequency signal line should be kept away from sensitive analog circuit equipment as much as possible.
For the ground wire, the entire PCB only needs one node to the outside world.
Therefore, the problem of digital and analog common ground must be dealt with inside the PCB.
However, the digital ground and the analog ground are actually separated inside the board, and they are not connected to each other.
It is only at the interface where the PCB is connected to the outside world (such as a plug, etc.).
The digital ground and the analog ground are slightly shorted,
Note that there is only one articulation point.
There are also different grounds on the PCB, which is determined by the system design.

Try to reduce their distribution parameters and mutual electromagnetic interference.
Susceptible components cannot be placed too close to each other,
Input and output components should be kept as far away as possible.
There may be a higher potential difference between certain components or wires,
The distance between them should be increased,
In order to avoid accidental short circuit caused by discharge.
Components with high voltage should be placed in places that are not easily accessible by hand during debugging.<\/li>\n<\/ol>\n\n\n\n\n
To consider the distribution parameters between components.
In general circuits, components should be placed in parallel as much as possible.
In this way, it is not only beautiful, but also simple to install and weld, and easy to mass produce.<\/li>\n<\/ol>\n\n\n\n
