1. Preparation of Base Materials: The process typically starts with preparing the base materials, which include woven glass fiber cloth and bismaleimide triazine (Bt) resin. These materials need to be clean and free from contaminants to ensure proper adhesion and performance.
2. Prepreg Preparation: Prepreg is a composite material made by impregnating reinforcement fibers with resin. In the case of Bt laminate substrates, the prepreg is prepared by impregnating the glass fiber cloth with Bt resin. This is often done using a combination of heat and pressure to ensure thorough impregnation and uniform distribution of the resin.
3. Layer Stacking: Multiple layers of prepreg are stacked together with conductive copper foil layers in between to form a multilayer structure. The copper foil serves as the conductive pathway for electrical signals on the PCB.
4. Lamination: The stacked layers are then pressed together under heat and pressure in a lamination process. This step bonds the layers together, forming a solid composite material with the desired thickness.
5. Curing: After lamination, the composite material undergoes a curing process. This involves subjecting the material to elevated temperatures for a specific period to fully cure the resin and achieve the desired mechanical and thermal properties.
6. Drilling and Plating: Holes are drilled into the substrate where electrical connections are needed. These holes are then plated with copper to provide conductivity between the different layers of the PCB.
7. Etching: Excess copper is removed from the surface of the substrate through an etching process, leaving behind the desired circuit pattern.
8. Surface Finishing: The final step involves applying a surface finish to the PCB to protect the copper traces from oxidation and ensure good solderability.

Overall, the fabrication process of a Bt laminate substrate requires precision and careful control of various parameters to ensure the quality and performance of the final product.
