Read about fr4 tg130 circuit board.TG represents glass transition, which is the temperature at which PCB substrate changes from rigid structure to viscous structure. Tg130 is measured in centigrade, which only means that 130 ℃ is the temperature range, which will lead to the transition of FR-4 TG 130 to its softening state. After cooling, it will return to its original properties. Tg130 Copper Based PCB with copper clad laminate and PCB universal PCB parts.Due to the characteristics of the FR-4 and the manufacturer’s experience, FR-4 is usually used for materials in PCB prototypes. It provides good insulation and arc resistance, i.e. the time taken for the insulation surface to become conductive under high voltage / low current arc. FR-4 (or flame retardant 4) is not a specific material, but a material grade, consisting of a composite of glass fiber woven cloth and flame retardant epoxy resin adhesive.
