1. Heat resistance class: F
2.Producing procedure: G10,G11 Epoxy plate is made from electricity fiberglass cloth immeresed with epoxy resin through hot pressing.
3. Characteristics: G10 laminate epoxy plate is with  high temperature resistance,high mechanical properties and dielectric properties,good heat resistance. In addition, FR4 sheet has anti-fire property.
4. Usage: It is widely used for electrical insulation as the components in the structure of electrical equipment,including the design of the switch, computer, printer circuit board, drilling pad with governance, such as PCB test shelf,can be used in humid conditions and transformer oil situation.
