FR4 PCB Characteristics
FR4 PCBs offer excellent thermal stability, high mechanical strength, and resistance to moisture and chemicals. The material consists of copper foil laminated onto a woven fiberglass substrate impregnated with epoxy resin, providing:
- Good dimensional stability across temperature ranges
- Low electrical conductivity to prevent short circuits
- Flame retardant properties for fire safety
- Wide application in consumer electronics, telecommunications, automotive, and industrial equipment
FR4 Material Types
- Standard FR4: Most common type with heat resistance of 140-150℃
- High Tg FR4: Withstands temperatures above 150℃
- High CTI FR4: Improved thermal conductivity (CTI > 600V)
- Non-copper FR4: For insulating boards and supports
- FR4 G10: Solid core with excellent mechanical and dielectric properties
High Frequency PCB Material Requirements
- Stable dielectric constant (Dk)
- Low dielectric loss (Df) for minimal signal loss
- Thermal expansion coefficient matching copper foil
- Low water absorption
- Excellent heat and chemical resistance
FR4 PCB Applications
FR-4 is widely used for printed circuit boards with copper clad laminates. Additional applications include:
- Relays and switches
- Busbars and washers
- Arc shields and transformers
- Screw terminal strips
Thermal Stability Properties
FR4 PCBs maintain performance across temperature ranges with:
- Glass Transition Temperature (Tg) of 130-180°C
- Low Coefficient of Thermal Expansion (CTE) of 12-18 ppm/°C
- Compatibility with standard soldering and reflow processes
- Adequate heat dissipation for most electronic applications
