Control of the impregnation process is very important to ensure that the resulting material has consistent properties.

Lamination: Impregnated fiberglass cloth is stacked into multiple layers and placed in a laminator along with a preheated press plate. Under the conditions of high temperature and pressure, the resin will harden, firmly bonding the layers of fiber cloth together to form a strong board.

Hardening: After the lamination process is complete, the pressed substrate needs to be hardened to ensure the resin is fully cured. This usually requires placing the substrate in a furnace and heating it at a specific temperature and time. Precise control of the hardening process is crucial to ensure the panels have the required properties.

Cutting: The hardened plate needs to be cut according to the customer’s requirements to get the required size and shape. This step is usually done with a CNC cutting machine, ensuring precision and consistency in cutting.

Processing: Finally, the cut sheets may require surface treatment, aperture drilling, copper foil covering, etc. to meet specific application requirements. These processing steps can be completed by CNC machine tools or other special equipment.
