First, the process of manufacturing BT laminate substrates begins with the preparation stage of raw materials. These raw materials usually include BT resin, glass fiber or cloth. BT resin is a high-performance resin with excellent thermal stability and mechanical strength, while glass fiber or cloth is used to enhance the structural strength of the substrate.

Next, the raw materials are pre-processed and formulated to ensure they meet specific manufacturing requirements. This may include the formulation of the resin and pre-treatment of the fiberglass to improve its adhesion and bond strength to the resin.

Subsequently, through a coating and pressing process, the resin and reinforcement materials are evenly coated together to form a prepreg. This step is critical as it determines the quality and performance of the final substrate. During this process, it is crucial to ensure an even distribution of resin and reinforcement to avoid unevenness during subsequent processing.

The prepreg is then placed in an environment of high temperature and pressure for curing and pressing. This process, called thermal curing, causes the resin to solidify at high temperatures into a strong structure that tightly bonds to the reinforcement. At the same time, high pressure ensures the density and thickness consistency of the substrate.

After heat curing is completed, the substrate is cut to the required size and surface treated to ensure that its flatness and surface roughness meet the requirements. This may include processes such as mechanical polishing or chemical treatments.

Finally, strict quality control and inspection are carried out to ensure that the manufactured BT laminated substrates meet customer specifications and standards. These include tests on dimensional accuracy, surface flatness, mechanical properties and electrical properties.

To sum up, the manufacturing process of BT laminated substrates goes through multiple precise process steps. The manufacturing of raw materials to final molded boards requires strict quality control and technical support to ensure that the final product has excellent performance and reliability.
