Solution Info
Introduction:
FR4 is a fire rated electrical-grade, dielectric fiberglass laminate epoxy resin program merged with a glass material substrate.The abbreviation “FR4” signifies: F (for flame) and R (for retardant).
FR4 grades substance provide superb chemical resistance, flame scores (UL94-VO) and electrical houses underneath dry and humid situations. FR4 also characteristics high flexural, affect, superior mechanical toughness and bond toughness at temperatures up to 130°C.
G10 content is a composite content produced of glass cloth and epoxy resin. It was developed as an aircraft content when it was invented, it can stand up to fantastic toughness. G-10 is not permeable with water and liquid, and it has the traits of insulation, anti-acid and alkali, and the excess weight is gentle.
A continuous woven glass material laminated with an epoxy resin. This grade is really substantial in mechanical power, has reduced water absorption and dissipation aspects and has outstanding electrical attributes, which are exhibited in excess of a wide assortment of temperatures and humidities.
