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.
