When we are making PCB board, we often need to use wiring design. The PCB wiring setting specifications are as follows:
1. Place power, ground and signal wires
After placing the components, it is time to route your power, ground, and signal traces to ensure that your signal has a clean, trouble-free transmission path. Here are some guidelines to remember this stage of your layout process.

2. Directional power and ground plane
It is always recommended that your power and ground planes are inside to your board while still being symmetrical and centered. This will help prevent your board from bending, which will also affect whether your components are positioned correctly. In order to power the IC, it is recommended to use a common rail for each power supply, make sure you have a solid and wide trace, and also avoid part-to-part daisy chain power lines.

3. Connect the signal line
Connect your signal tracking to comply with your guidelines. It is recommended to always place traces between components as short and directly as possible. If your component placement forces the horizontal trace to be routed on one side of the board, always place the trace vertically on the opposite side.

4. Define the clear width
Your design may require different networks that will carry a wide range of current, which will dictate the required network width. Considering this basic requirement, it is recommended to provide a width of 0.010 for low-current analog and digital signals. When your trajectory carries more than 0.3 amps, it should be wider. Here is a free track width calculator to make this process easy.

5. Things separate
You may have experienced how high voltage and current spikes in power circuits can interfere with your low voltage and current control circuits. In order to reduce this interference problem, follow the following guidelines:
a. Separation: Ensure that each power level maintains power grounding and control grounding. If you must tie them to your PCBs, make sure it is towards the end of your supply path.
b. Placement: If you have placed the ground plane on the middle layer, make sure to set a small impedance path to reduce the risk of any power Flexible PCB circuit interference and help protect the control signal. Follow the same guidelines to maintain the Y axis.
