1.Typical preparation methods

The manufacturing of EPGC202/FR-4 Epoxy-Phenolic Glass Fabric Laminate involves several careful steps to ensure its high mechanical, electrical, and thermal properties. Initially, alkali-free E-glass fabric is woven to yield a uniform and smooth fabric. This fabric is then impregnated with a specially formulated brominated epoxy resin system containing epoxy resins, hardeners, and flame-retardant additives. The impregnation process is meticulously controlled to achieve a consistent resin distribution and ensure uniform quality of the laminate. Following impregnation, the resin-coated fabric undergoes a B-stage curing process, where it is partially cured under controlled temperature and pressure to form a sticky, partially cured material known as prepreg. These prepreg layers are then stacked in the desired orientation and thickness according to specific application requirements. The stacked layers are subjected to high-pressure hot pressing, where heat and pressure are applied to fully cure the resin, solidifying the laminate and achieving the required thickness and mechanical properties. After curing, the laminate is cooled, trimmed to the proper size, and subjected to rigorous quality control tests to ensure it meets the required standards for mechanical strength, dielectric performance, moisture resistance, and flame retardancy. The result of this thorough manufacturing process is a durable, high-performance laminate suitable for a variety of applications, including printed circuit boards, electrical insulation components, and structural parts across various industries.
