What Is FR4 PCB Material?
FR-4 is a high-strength, high-resistant, glass-reinforced epoxy laminate material used to fabricate printed circuit boards (PCBs). The National Electrical Manufacturers Association (NEMA) defines it as a standard for glass-reinforced epoxy laminates.
The FR stands for flame retardant, and the number 4 differentiates this type of laminate from other similar materials. This particular laminate has woven glass-reinforced epoxy resin.
FR-4 PCB refers to the board manufactured with adjacent laminate material. This material is incorporated in double-sided, single-sided, and multi-layered boards.
Standard FR-4 Material Properties
- High Glass Transition Temperature (Tg) (150Tg or 170Tg)
- High Decomposition Temperature (Td) (> 345º C)
- Low Coefficient of Thermal Expansion (CTE) (2.5%-3.8%)
- Dielectric Constant (@1 GHz): 4.25-4.55
- Dissipation Factor (@ 1 GHz): 0.016
- UL rated (94V-0, CTI = 3 minimum)
- Compatible with standard and lead-free assembly
FR4 PCBs are known for their excellent thermal stability, high mechanical strength, and resistance to moisture and chemicals. These properties make them suitable for a wide range of applications, including consumer electronics, telecommunications, automotive, industrial equipment, and more.
