How to design a mixed media PCB?

The design process of mixed-media PCBs involves multiple key steps, which require comprehensive consideration of the characteristics of different materials and the performance requirements of the circuit board. The design process of mixed media PCB will be introduced in detail below:

Before starting the design, you first need to clarify factors such as the function, performance requirements, and environment of the circuit board. This includes determining the number of plies, board thickness, electrical characteristics, thermal management needs, etc.

Select the appropriate material combination based on design needs and performance requirements. Common mixed media PCB materials include FR4, Rogers, Isola, etc. They have different dielectric properties, thermal conductivity and mechanical strength, and designers need to make reasonable matches based on specific requirements.

After the materials are determined, a layer-by-layer design is performed to determine the function and layout of each layer. According to the complexity of the circuit and signal transmission requirements, determine the signal layer, ground layer, power layer, etc. The stack-up design of mixed-media PCBs requires special attention to matching and impedance control between different materials.

When laying out circuits, factors such as signal integrity, electromagnetic compatibility, and thermal management need to be considered. Proper circuit layout can minimize signal crosstalk and electromagnetic interference and improve circuit reliability and performance.

Conduct route planning based on circuit layout to ensure optimization of signal transmission paths. For high-speed signals and microwave frequency circuits, special attention needs to be paid to issues such as matching impedance and signal transmission delay.

When placing devices, factors such as spacing between devices, ease of heat dissipation, and wiring need to be considered. Reasonable device layout can reduce circuit noise and temperature and improve system stability and reliability.

During the design process, attention should be paid to energy conservation and environmental protection. By optimizing circuit layout and material selection, power consumption and heat loss are reduced to achieve energy saving and environmental protection goals.

After the design is completed, simulation verification is performed to ensure the performance and stability of the circuit. Through electromagnetic simulation, thermal simulation and other means, the electrical characteristics and thermal management effect of the design are evaluated, and potential problems are discovered and solved in a timely manner.

Based on simulation results and actual test feedback, the design is optimized and improved. Continuous optimization of design can continuously improve the performance and reliability of circuits to meet changing needs.

Finally, design documents and manufacturing files are generated and communicated with manufacturers. Design documents should include information such as detailed circuit diagrams, stack-up diagrams, device lists, and manufacturing requirements to ensure a smooth manufacturing process.

Through the above design process, designers can realize the optimized design of mixed media PCB to meet the needs of different application scenarios and maximize its performance advantages.

What is the manufacturing process of mixed media PCB?

The manufacturing process of mixed-media PCBs is a precise and complex process that requires precise control and coordination of multiple steps. The manufacturing process of mixed media PCB will be introduced in detail below:

First, mixed media PCB manufacturing starts with material preparation. According to the design requirements and performance requirements, appropriate FR4, Rogers, Isola and other materials are selected, and they are accurately cut and processed to ensure that the size and surface quality of the panels meet the requirements.

Next is the production of the printed circuit layer. According to the PCB design file, the circuit pattern is printed onto the board surface using printing technology. This step requires high-precision equipment and precise operations to ensure the clarity and accuracy of the circuit pattern.

This is followed by chemical etching and cleaning. The printed circuit board is placed in a chemical solution and the unprotected metal parts are removed through an etching process, leaving the desired circuit structure. Subsequently, the panels are thoroughly cleaned to remove residual chemicals and dirt to ensure a clean and smooth surface.

Drilling and plating are the next critical steps. Use a high-speed drill press to drill holes into the circuit board for mounting components and making electrical connections. Subsequently, a layer of metal is plated on the hole wall through an electroplating process to enhance the electrical conductivity of the hole wall for subsequent welding and connection.

Next comes the lamination and lamination of the circuit boards. The single-layer circuit board that has been drilled and plated is combined with other laminated materials (such as copper foil, dielectric layers, etc.) to form a multi-layer structure. The various layers of boards are tightly pressed together using a heat press to form a complete circuit board structure.

Finally comes surface treatment and inspection. The surface of the circuit board is coated and gold-plated to enhance its corrosion resistance and conductivity. Rigorous inspection and testing are then conducted to ensure that the quality and performance of the circuit boards meet design requirements and comply with industry standards and specifications.

Through the above carefully designed and strictly controlled manufacturing process, mixed media PCB can achieve high-quality, high-performance production, providing reliable support and guarantee for the application of electronic products.
