Product Description
Product Description
Product Composition:Composite materials laminated by epoxy resin and glass fiber cloth are widely used in electronics, electrical, communications and other fields due to their excellent electrical properties, mechanical strength and heat resistance. The "FR" in FR4 stands for "Flame Retardant", indicating that it has good flame retardant properties.
Performance Characteristics
Electrical insulation: high insulation resistance, low dielectric constant, suitable for high-frequency circuits.
Mechanical strength: high bending strength and impact resistance.
Heat resistance: can remain stable at higher temperatures, usually 130°C to 140°C.
Flame retardancy: meets UL94 V-0 flame retardant standards and has good fire resistance.
Chemical resistance: good resistance to most chemicals.
Dimensional stability: can remain dimensional stable under changes in temperature and humidity.
High performance: excellent electrical and mechanical properties, suitable for demanding applications.
Flame retardancy: meets strict flame retardant standards and is highly safe.
Versatility: suitable for a variety of electronic and electrical applications.
Processability: easy to cut, drill and surface treat.
Environmental protection: some products comply with environmental protection standards such as RoHS.
Application Fields
PCB manufacturing: FR4 is the main material for manufacturing printed circuit boards (PCBs) and is widely used in electronic devices.
Electrical insulation: used for insulating components of electrical equipment such as transformers, relays, switches, etc.
Communication equipment: used for high-frequency communication equipment such as antennas and filters.
Industrial control: used for circuit boards and insulating components in industrial control systems.
Automotive electronics: used for automotive electronic control units (ECUs) and sensors, etc.
Aerospace: used for high-performance circuit boards in aerospace electronic equipment.
