The temperature and pressure need to be strictly controlled during the lamination process to ensure that the copper foil is firmly bonded to the substrate.

Once the copper foil layer is successfully bonded to the substrate, the next step is to form the circuit pattern through an etching process. Etching is the use of chemical solutions or mechanical methods to remove unnecessary copper foil, leaving only the parts required to form circuit paths. This step requires precise control of etching time and solution concentration to avoid excessive etching or residue of circuit paths.

After completing the circuit patterning, drilling and via coating are next. These holes are used to mount electronic components and connect signal transmission between circuit layers. Via-hole coating is a metal layer coated on the hole wall to improve connection reliability and conductive performance.

To enhance the board’s durability and performance, metal plating and protective coatings are applied next. Metal plating is often used to enhance electrical conductivity and corrosion resistance, while protective coatings are used to protect circuits from external environmental effects, such as moisture, chemicals, and mechanical wear.

The final step is final testing and quality control. Ensure metal substrates meet design specifications and customer requirements through electrical testing, optical inspection and mechanical performance evaluation. These tests include checking circuit connectivity, thermal conductivity and environmental resistance to ensure each metal substrate will perform well in real-world applications.

Through the above precise manufacturing process, metal substrates can meet the needs of various high-demand electronic applications, from consumer electronics to industrial equipment, providing a solid foundation and reliable support for modern technological innovation.
