Introduction
Our company has been supplying water-green FR-4 epoxy glass fiber cloth laminate for a long time. Thicknesses are: 0.1mm to 120.mm, sheet specifications: 1020mm * 1220mm, 1220mm * 2440m. Colors are white (aqua green), yellow, black, and colored.
The glass fiber board and epoxy board are different according to the use. The industry generally refers to: FR-4 Epoxy Glass Cloth insulation board, epoxy board, epoxy board, brominated epoxy board, FR-4, glass fiber board, ring Oxygen glass cloth board, epoxy glass cloth laminated board, glass fiber board, FR-4 reinforced board, flexible circuit board reinforced board, FR-4 epoxy board, flame-retardant insulation board, FR-4 laminated board , FR-4 light board, circuit board drilling pad.
Our water-green FR-4 epoxy glass fiber cloth laminate is used in products with high performance electrical insulation requirements, such as FPC reinforcement board, PCB drilling pad, glass fiber meson, potentiometer carbon film printed glass fiber board, precision testing Boards, electrical (electrical) equipment, insulation struts, insulation pads, high-voltage insulation boards, motor insulation, electronic switch insulation, fixture testing, PCB testing, and can be used in transformers in humid environments, It can also be used for precision planetary gears (grinding gears) for polishing of touch film frequency chips.
