lasikuituepoksilevy
Lasikuituepoksilevy, often referred to as FR-4, is a widely used composite material made from woven fiberglass cloth with an epoxy resin binder. This combination results in a rigid, strong, and electrically insulating material that is highly valued in the electronics industry. The fiberglass provides mechanical strength and dimensional stability, while the epoxy resin offers excellent electrical insulation properties and resistance to heat and moisture.
FR-4 is most commonly recognized as the substrate material for printed circuit boards (PCBs). Its properties
Beyond PCBs, lasikuituepoksilevy finds applications in various electrical and mechanical components where a combination of strength,
