What is the PCB manufacturing process?

The PCB manufacturing process is a precise and complex process involving multiple key steps, each step is crucial and directly affects the quality and performance of the final product. Let’s walk through the process together.

The first step in PCB manufacturing is to verify the design. Before sending design files to the production line, engineers must ensure the accuracy and consistency of the design. This includes checking circuit layout, component location and trace connections, as well as performing verification steps such as Design Rule Check (DRC) and Electrical Rule Check (ERC). Through these verifications, you can ensure that the design complies with specifications and reduce errors and problems that may arise during subsequent manufacturing processes.

Before starting to manufacture the PCB, you need to prepare the required materials. This includes the substrate material (usually FR-4 or similar material), copper foil (used to form the conductive layer), and other auxiliary materials such as copper clad foil and solder resist ink. These materials must undergo strict quality controls to ensure they meet design requirements and have the required performance characteristics.

The next step in manufacturing a PCB is to convert the design files into an actual circuit board. This process is often called “panning.” First, the substrate material needs to be cut to the required size and surface treated to facilitate subsequent material adhesion. Then, the surface of the substrate is covered with a thin layer of copper foil to form a conductive layer. This step is critical because it determines how the subsequent circuit is formed and connected.

On the conductive layer, the pattern in the design file is transferred to the surface of the copper foil through photolithography technology. This process involves applying photoresist, exposing the photoresist, and etching or chemically etching the portions not protected by the photoresist. This forms the circuit pattern on the circuit board, including wires, holes and pads.

After patterning is complete, the circuit board needs to be metallized, which involves covering the wires and pads with a protective metal layer, usually gold or tin plating. This step helps improve the reliability and corrosion resistance of the weld. Next, the surface of the circuit board is coated, including copper foil and solder mask ink, to protect the circuit pattern and improve the durability of the circuit board.

After completing the above steps, the board requires final inspection and testing. This includes visual inspection, X-ray inspection and electrical testing to ensure the board meets design specifications and has the required performance characteristics. Any defects or issues discovered will be documented and corrected to ensure the quality and reliability of the final product.

Through the above steps, the PCB manufacturing process ensures that every link from design to final product can be realized accurately and reliably, thus providing a reliable foundation for the development and application of modern electronic equipment.
