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 make it ideal for supporting and connecting electronic components. The material can be easily machined, drilled, and cut, allowing for complex designs. It also exhibits good flame retardant characteristics, which is a critical safety feature in electronic devices. The manufacturing process typically involves impregnating fiberglass cloth with epoxy resin, layering these sheets, and then curing them under heat and pressure.

Beyond PCBs, lasikuituepoksilevy finds applications in various electrical and mechanical components where a combination of strength, insulation, and cost-effectiveness is required. This includes enclosures, structural parts in electrical equipment, and insulating barriers. Its versatility, good performance, and relatively low cost have cemented its position as a staple material in modern manufacturing.
