What is 4 Layer PCB?
It means that the circuit printed board is made of 4 layers of glass fiber, which can reduce the cost of the PCB but has poor performance.

4 Layer PCB Drawing Process
1. Draw circuit schematics and generate netlists.
The process of drawing a schematic diagram involves the drawing of components and the drawing of the package. It is basically no problem to master these two kinds of drawing schematic diagrams.
2. Planning the circuit board.
How many layers to paint?
Are the components arranged on one side or on both sides?
What is the size of the circuit board?
These are things to consider, customizing ahead of time.
3. Set various parameters
Arrangement parameters, slab parameters, are based on the system default, only need to set a small number of parameters.
4. Load netlist and component package
The netlist is the interface between the circuit schematic editing software and the printed circuit board PCB design software. Only after the netlist is loaded, the circuit board can be automatically routed.
5. Layout of components
In most cases manual layout, or a combination of automatic and manual.
Components are evenly spaced for easy installation, plug-in, and soldering operations. The text is arranged in the current character layer, the position is reasonable, pay attention to the orientation, avoid being blocked, and facilitate production.
6. Wiring
For automatic wiring or manual wiring, the layout should be planned before wiring to match the internal electrical layer, and the internal electrical layer should be hidden for wiring.
The internal electrical layer is usually a whole piece of copper film. When the pad with the same network name as the copper film passes through the internal electrical layer, the system will automatically connect it to the copper film, and the pad/via is connected to the internal electrical layer. The form as well as the copper foil and other pads and clearances that are not part of the net can be set in the rules.
