1. The basic structure of Wd Power PCB Assembly
The component library of Power PCB is its core component, which contains the packaging information of various electronic components. These component libraries are usually divided into four sub-libraries: Part Type component type library, Part Decal component packaging library, CAE logic packaging library and Line line library. These sub-libraries store electrical information, physical packaging information, logical packaging information and circuit information of components respectively.

2. The design cycle of Wd Power PCB Assembly
The design process of Power PCB is usually divided into three stages: pre-preparation stage, design stage and post-design check and data output stage. The main task of the preliminary preparation stage is to make components and save them in the component library. The design stage includes drawing schematic diagram, making package, importing netlist, setting rules, layout, wiring and other steps. In the later stage of design check and data output, the design is checked and the CAM file for manufacturing is output.

3.the key steps of Wd Power PCB Assembly

Component package manufacturing

Component packaging is the foundation of Power PCB Assembly. Packaging reflects the size and shape of components, including the size and distribution of pins. When designing PCB, it is necessary to make corresponding packages according to the actual size and shape of components and save them in the component library.

overall arrangement

Layout is the process of placing components on PCB according to predetermined positions. Reasonable layout can improve the performance and reliability of the circuit, while reducing the complexity and interference of wiring. In Power PCB, layout is usually done by combining automatic layout with manual layout.

wiring

Wiring is the process of realizing the electrical connection between components through wires or copper foils. In Power PCB, wiring needs to follow certain rules and principles, such as signal lines should be as short as possible and uniform in thickness, and power lines should be as wide as possible to reduce loop resistance.

Check and output

After the layout and wiring are completed, the design needs to be verified to ensure that it meets the predetermined requirements and standards. After verification, CAM files can be output for manufacturing.

4.Precautions

Selection of component packaging

In Power PCB Assembly, it is necessary to choose the package of components correctly. The choice of package should be based on the actual size and shape of the component to ensure its correct placement and connection on the PCB.

Optimization of layout and wiring

Layout and wiring are the key links in Power PCB Assembly. Reasonable layout and wiring can improve the performance and reliability of the circuit, while reducing interference and wiring complexity. Therefore, in the layout and wiring, it is necessary to fully consider the function and performance requirements of the circuit and follow certain rules and principles.

Rigidity of verification and testing

After the Power PCB Assembly is completed, the design needs to be strictly checked and tested. The purpose of verification and testing is to ensure that the design meets the predetermined requirements and standards, and at the same time, to find and solve possible problems and defects.
