1.       Common Preparation Methods

The preparation of EPGC204/FR-5 epoxy-phenolic glass fabric laminate involves a meticulous process that begins with selecting high-quality, alkali-free glass fiber cloth. This cloth is then impregnated with a specially formulated epoxy-phenolic resin mixture, ensuring thorough saturation to achieve optimal mechanical and electrical properties. The impregnated fabric layers are subsequently stacked and subjected to a hot pressing process under controlled temperature and pressure conditions. This step facilitates the curing of the resin, resulting in a rigid, durable laminate with enhanced thermal stability and flame retardancy. The final product undergoes cooling and precision cutting to meet specified dimensions and tolerances, ensuring consistency and reliability for its intended applications. This comprehensive manufacturing process ensures that EPGC204/FR-5 laminate exhibits superior mechanical strength, excellent electrical insulation, and resistance to high temperatures and moisture, making it suitable for demanding electrical and mechanical applications.
