PCB layout knowledge

In design, layout is an important part. The quality of the layout results will directly affect the effect of the wiring, so it can be considered that a reasonable layout is the first step in the success of PCB design.

There are two ways to layout, one is interactive layout and the other is automatic layout. Typically, it is adjusted through an interactive layout based on automatic layout. In the layout, the gate circuit can be re-wired according to the condition of the wiring. When assigned, the two doors are swapped, making it the optimal layout for easy routing. After the layout is completed, the design files and related information can be returned and marked on the schematic, so that the relevant information on the PCB is consistent with the schematic, so that the design synchronization can be created and modified in the future, and simulation can be performed at the same time. Updated information to achieve board level verification of electrical performance and functionality of the circuit.

 - Consider the overall beauty

The success of a product, one must focus on the internal quality, and the second is to consider the overall aesthetics, both of which are perfect considering the product to be successful.

On the PCB, the layout of the components must be balanced and orderly, rather than top-heavy or sinking.

 - Layout check

Does the printed circuit board size match the size of the machined drawing? Can it meet PCB manufacturing process requirements? Is there a positioning tag?

Is there a conflict between components in 2D and 3D space?

Are the component layouts dense and orderly, neatly arranged? Is this all done?

Is it easy to replace parts that need to be replaced frequently? Is it convenient to plug the board into the device?

Is there a proper distance between the heating element and the heating element?

Is it convenient to adjust the adjustable components?

Is there a radiator that needs to be heated? Is the airflow smooth?

Is the signal flow smooth and the shortest interconnect?

Are plugs, sockets, etc. contradicting mechanical design?

Have you considered the interference problem of the line?
