Thermal Stability Characteristics
FR4 PCBs demonstrate excellent thermal stability, maintaining performance across a wide temperature range without warping, delamination, or failure.
Key Thermal Properties: Glass Transition Temperature (Tg) of 130-180°C, Coefficient of Thermal Expansion (CTE) of 12-18 ppm/°C, and thermal conductivity suitable for most electronic applications.
These boards withstand standard soldering and reflow processes while maintaining dimensional stability. Additional thermal management features like thermal vias can be incorporated for enhanced performance.
Material Advantages
FR4 PCBs combine woven fiberglass and epoxy resin for superior mechanical strength, moisture resistance, and flame retardancy. The copper-clad substrate provides reliable electrical connections with excellent dimensional stability.
Ideal for demanding applications in consumer electronics, telecommunications, automotive systems, and industrial equipment where reliability and safety are critical.
