FR-4 Epoxy Sheet Product Introduction: This material is made from electronic-grade fiberglass cloth and epoxy resin through high-temperature and high-pressure processing. It features high voltage resistance, excellent insulation properties, and fire resistance (flammability rating 94V-0). It is primarily used in products such as electronic transformers, inductors, and power insulation. Our company provides full-process services, including pressing, stamping, drilling/routing machining, PIN insertion (dummy pins), and other processing steps. We can deliver samples within one hour, produce molds in two days, and commence mass production in three days, achieving a relatively fast pace in the industry.
