Next is the PCB design stage. When designing a PCB, it is necessary to lay out the electronic components on the PCB board and design appropriate circuit connections to achieve the functional requirements of the device. At the same time, parameters such as the number of PCB layers, line width, and line spacing also need to be considered to meet the performance and stability requirements of the circuit.

Once the PCB design is completed, the PCB manufacturing stage is entered. This includes preparation of the substrate, coating, exposure, etching, drilling, plating, and many other steps. In the substrate preparation stage, a suitable substrate material needs to be selected, cut and cleaned. Then coating is performed, the photosensitive adhesive is coated on the surface of the substrate, and the PCB pattern is transferred to the photosensitive adhesive through exposure. This is followed by etching, where the unwanted parts are etched away, leaving the desired circuit pattern. Drilling and plating are done to form connection holes and metal layers for subsequent component installation and connection.

During the manufacturing process, special attention needs to be paid to several key points.
