Graphics Conversion: PCB design files are converted into production graphics that can be used for manufacturing. This includes converting design data into Gerber files to facilitate subsequent graphics imaging and processing.

Image processing: Gerber files undergo graphic imaging processing, and the circuit pattern is transferred to a substrate covered with photosensitive material through photolithography or laser irradiation.

Chemical Etching: The uncovered portions of the PCB will be removed by chemical etching to form the pattern of the circuit board. This process requires strict control of time and chemical concentration to ensure accuracy and consistency.

Drilling: Drilling holes in a circuit board for mounting electronic components and connecting circuits. The drilling process requires high-precision drilling machines and drill bits to ensure accuracy of hole diameter and location.

Surface treatment: The PCB surface may require surface treatment, such as metal spraying, tin spraying, or lead spraying, to improve soldering performance and corrosion protection.

Component mounting: The surface-treated PCB will be transferred to the automated component mounting line. Here, electronic components will be mounted precisely to their designated locations and secured to the PCB via soldering or other connection techniques.

Quality Control and Testing: Once manufactured, each multi-cavity PCB goes through strict quality control and testing procedures. This includes steps such as visual inspection, soldering quality inspection, electrical connectivity testing and functional testing to ensure each PCB meets specifications and achieves expected performance levels.
