Typically, these films include high-performance materials such as special polyimide (PI) or polytetrafluoroethylene (PTFE). The film stacking process requires a high degree of precision and stability to ensure the thickness and placement of each layer is accurate.

Circuit Patterning

Once the film stacking is complete, the next step is circuit patterning. This step involves patterning circuit traces on the film, typically using techniques such as photolithography or laser cutting. These lines will become the channels connecting various devices and components, so their accuracy and quality are critical to the performance of the entire substrate.

Metallization

After completing the circuit pattern, the next step is metallization. This step involves coating the surface of the substrate with a layer of metal, usually a conductive metal such as copper or silver. The purpose of metallization is to form a conductive path for a circuit and to provide the electrical connections required by the circuit. This requires the use of advanced processes such as chemical deposition and vacuum coating to ensure the uniformity and adhesion of the metal layer.

Throughout the manufacturing process, precision manufacturing processes are key to ensuring substrate quality and performance. Each step requires strict control and monitoring to ensure that the size, thickness, circuit accuracy and other parameters of the substrate meet the design requirements. Deviations in any link may lead to a decrease in substrate performance or an increase in defective products, so quality control during the manufacturing process is crucial.
