The design phase also includes selecting appropriate materials and processes to ensure the performance and reliability of the final product.

Graphicalization: After the design is completed, the engineer converts the PCB design drawing into a graphical file, usually in Gerber file format. These files include information about each layer of the PCB (such as copper layer, drilling layer, printing layer, etc.) for subsequent manufacturing processes.

Printing: Next is the printing stage of the PCB. At this stage, engineers transfer the design drawings to a substrate material, which is typically FR-4 fiberglass reinforced epoxy resin. Through the printing process, the copper foil layer is combined with the substrate material to form the basic structure of the PCB.

Gold plating: PCB surface treatment is a very critical step. Commonly used surface treatment processes include HASL (Hot Air Solder Leveling) and ENIG (Electroless Nickel Immersion Gold). These processes can improve the soldering performance and oxidation resistance of PCB.

Layer arrangement: Layer arrangement refers to arranging and assembling the various layers of the PCB according to the design requirements. This includes stacking the inner copper foil layer, electrolytic layer, etc. according to the design requirements, and curing them through a lamination or hot pressing process.

Plug-in assembly: The last stage is plug-in assembly, which is to install electronic components, connectors and other components onto the PCB. This process is often performed using automated equipment to increase efficiency and accuracy.
