FR-4 glass epoxy is a popular and versatile high-pressure thermoset plastic laminate grade with good strength to weight ratios. With near zero water absorption, FR-4 is most commonly used as an electrical insulator possessing considerable mechanical strength.

Aug 23, 2022 · FR-4 is a dielectric glass-reinforced epoxy laminate material used as a base material for insulation in printed circuit boards. This PCB substrate is a low-cost, most commonly used material with good electrical and environmental properties.

FR4 is the backbone material upon which most rigid circuit boards are built. However, many are unaware of what FR4 is, let alone why it is the most popular PCB base. Read on to learn more about FR4 printed circuit boards, such as what they are, why they are so popular and how FR4 PCB specifications compare to other options within the industry.

FR-4 glass epoxy is a popular and versatile high-pressure thermoset plastic laminate with good strength to weight ratio. With near zero water absorption, FR-4 is most commonly used as an electrical insulator possessing considerable mechanical strength.

Atlas Fibre offers FR-4, a glass epoxy laminate that is similar to G-10 with the addition of being flame retardant. FR-4 is known for having good characteristics for fabrication, mechanical strength, and insulation resistance.

Jul 27, 2021 · FR stands for flame retardant, and the number ‘4′ indicates woven glass-reinforced epoxy resin. The characteristics of FR4 vary significantly depending on the manufacturer, although it is commonly known for its mechanical strength and water resistance.

FR4 glass epoxy is the most common base material used in the fabrication of printed circuit boards (PCB) today. Over 90% of rigid PCBs manufactured use some grade of FR4 dielectric. But what exactly does the FR acronym mean? And why …

Jul 2, 2024 · FR4, often known as glass-reinforced epoxy, is made up of two major components: woven fiberglass cloth and epoxy resin. A typical FR4 PCB comprises a FR4 PCB material sandwiched between two copper sheets. Fiberglass cloth offers rigidity and strength.

FR-4 is, at its most basic level, a standard for materials used in electrical applications. See the article to the right (or below) that explains why FR-4 is a distinct designation from it’s non flame retardant cousin G-10. The NEMA Standard provides generic category recognition of grades based on their construction, reinforcement, and resin.

Feb 7, 2025 · High Heat Resistance: FR-4 can handle temperatures ranging from 130°C to 180°C, suitable for high-temperature environments. Excellent Electrical Insulation: Provides superior dielectric properties, making it ideal for high-frequency and high-voltage applications.
