Micro Cavity PCB is a special type that creates tiny cavities on or within the PCB, often used to house sensitive electronics, sensors, or other components. The basic principle of designing Micro Cavity PCB is to rationally plan the circuit layout and chamber structure to ensure the performance and stability of the circuit and provide accurate guidance for the manufacturing of the chamber.

Determine needs and specifications: First, clarify the purpose of the design and the required specifications. This includes circuit layout, chamber size and shape, and the type and number of electronic components.

Choose the right CAD software: Choose a CAD software suitable for PCB design, such as Altium Designer, Eagle or KiCad, etc. Ensure that the software supports the design and simulation of microstructures.

Draw a circuit diagram: Use CAD software to draw a circuit diagram, including the location, connections, and routing of electronic components. Consider the location and shape of the chamber in the design, and arrange it appropriately to ensure the stability and performance of the circuit.

Add a chamber structure: Add a chamber structure to the PCB according to design requirements. The 3D module of the CAD software can be used to simulate and design the microchamber, ensuring that it matches the circuit layout and provides enough space to accommodate the target components.

Optimized Layout: Circuit layout and chamber structure are optimized to minimize interference and cross-talk. Ensure adequate spacing between electronic components and chamber to avoid heat build-up and signal interference.

Simulate and test: Simulate and test in CAD software to verify the performance and stability of your design. Conduct circuit simulation and thermal analysis through simulation software to evaluate the working status of the circuit and the heat dissipation effect of the chamber.

Adjustments and modifications: Make adjustments and modifications to the design based on simulation and test results. Circuitry may need to be rearranged or the size and shape of the chamber adjusted to meet design needs and performance requirements.

Generate manufacturing files: Finally, generate the Gerber files and BOM tables required for PCB manufacturing, and communicate with the PCB manufacturer to ensure design accuracy and manufacturability.

What is the manufacturing process of Micro Cavity PCB?

The manufacturing process for Micro Cavity PCBs is a complex and precise process consisting of multiple critical steps that ensure the quality and performance of the final product. Let’s walk through the process together.

The manufacturing process of Micro Cavity PCB begins with the preparation of materials. The commonly used substrate is fiberglass reinforced resin board (FR-4), the surface of which is coated with a layer of copper foil. First, the original sheets are cut into substrates of appropriate size according to the design requirements for subsequent processing and handling.

Next is the production of the printed circuit layer. In this step, a layer of photosensitive material is coated on the surface of the substrate through chemical processing or mechanical engraving. Then, using the design pattern generated by CAD software, the pattern is transferred to the photosensitive layer through exposure.

After exposure, the photosensitive layer in the unexposed area is removed by chemical etching to expose the copper foil. After etching, the plate needs to be thoroughly cleaned to remove residual photosensitive substances and etchants to ensure that the surface of the plate is clean and free of contamination.

Drilling is an integral step in the manufacturing of Micro Cavity PCBs. According to the design requirements, use a drill press to drill holes in the board to provide channels for the connection and assembly of the circuits. After drilling is completed, electroplating is performed to strengthen the circuit connection, improve conductivity, and protect the circuit from oxidation and corrosion by electroplating a layer of metal on the copper foil.

Finally, the circuit board is assembled and tested. Install various electronic components on the PCB according to design requirements and solder them. The PCB is then functionally tested and performance verified using automated or manual test equipment to ensure it meets design specifications and quality standards.

Overall, the Micro Cavity PCB manufacturing process includes key steps such as material preparation, printed circuit layering, chemical etching and cleaning, drilling and plating, and final assembly and testing. Every step is critical and has a direct impact on the quality and performance of the final product.

High-performance materials tend to be more expensive but may offer better performance and reliability.

Secondly, PCB design complexity also directly affects cost. If the PCB needs to contain complex circuits, multi-layer designs, or special requirements such as micro-apertures, manufacturing costs will increase accordingly. In addition, special process requirements or customized requirements may also increase costs.

Manufacturing scale is another important factor. Large-scale production often reduces unit costs because fixed costs can be spread over more products. In contrast, the costs of small-scale production may be higher because fixed costs are allocated at a lower rate.

Finally, supply chain management also has an impact on costs.
