At the beginning of the design, a comprehensive analysis of the project requirements is first required. This includes determining the functions and components required for each cavity and how they are connected to each other. At the same time, factors such as overall size, performance indicators, and power consumption also need to be considered.

Schematic design is often done before actual layout begins. In the schematic diagram, connect all electronic components according to their functions and ensure the logical correctness of the circuit. This stage is the basis of the design process and directly affects subsequent layout and wiring.

Layout design is the process of placing the components in the schematic onto the PCB board. For multi-cavity PCBs, components in different cavities need to be arranged in appropriate locations to save space to the greatest extent and ensure the stability and reliability of the circuit. Additionally, layout rules between components need to be considered to reduce interference and cross-coupling.

Connection design is the determination of wiring paths between components, usually through wiring. In multi-cavity PCB design, special attention needs to be paid to signal transmission and power distribution between different cavities to ensure that the connections between each cavity meet design requirements and to minimize signal interference and power loss.

Multi-cavity PCBs usually adopt a multi-layer board design to accommodate more electronic components and improve signal transmission efficiency. In a stacked design, it is necessary to determine the function and layout of each layer and ensure that the connections between the layers are smooth and reliable.

Thermal management is a critical issue for high-performance multi-cavity PCB designs. During the design process, it is necessary to consider the heat conduction paths between each cavity, as well as the placement of radiators and cooling fans to ensure that the system does not overheat during long-term operation.

After the design is completed, performance simulation is usually performed to verify the correctness and stability of the design. Through simulation analysis, potential problems can be discovered and adjustments can be made in a timely manner to ensure that the final product can meet performance indicators and quality requirements.

In summary, designing a multi-cavity PCB is a complex and delicate process involving multiple key steps and technical considerations. Only through careful analysis and design can we ensure that the final product meets the expected function and performance requirements.
