There are two ways to layout, one is interactive layout, the other is automatic layout. Generally, it is adjusted by interactive layout based on automatic layout. In the layout, the gate circuit can be re-routed according to the condition of the wiring. Allocation, the two gates are swapped, making it an optimal layout for easy routing. After the layout is completed, the design file and related information can be returned and marked on the schematic diagram, so that the relevant information in the PCB board is consistent with the schematic diagram, so that the future creation and modification of the design can be synchronized, and at the same time, the simulation is performed. The information is updated to enable board-level verification of the electrical performance and functionality of the circuit.
1. Consider the overall beauty
The success of a product, one must pay attention to the internal quality, and the second is to take into account the overall aesthetics, both of which are perfect to consider the product to be successful.
On a PCB board, the layout of components must be balanced, orderly, and not top-heavy or sinking.
2. Layout check
Does the printed board size match the size of the machined drawing? Can it meet the PCB manufacturing process requirements? Is there a positioning marker?
Are there any conflicts between components in 2D and 3D space?
Are the component layouts dense and orderly, neatly arranged? Is it all finished?
Can components that need to be replaced frequently be replaced easily? Is it convenient to insert the board into the device?
Is there a proper distance between the thermal element and the heating element?
Is it convenient to adjust the adjustable components?
Where is the heat sink installed where heat is needed? Is the air flow smooth?
Is the signal flow smooth and the shortest interconnected?
Is the plug, socket, etc. contradicting the mechanical design?
Is the interference problem of the line considered?
