FR-4 substrate, as an epoxy resin glass fiber composite material, is well-known for its excellent electrical insulation and thermal stability. In multi-layer PCB circuit boards, FR-4 substrate is the basis for supporting circuits and plays a vital role in signal transmission.
Considering the demand for high-frequency signals in modern electronic products, the FR-4 substrate ensures the stability of signals during high-speed transmission with its low-loss characteristics, so that designers do not need to worry about signal interference when pursuing speed and accuracy.
In high-power applications, thermal management becomes an important design consideration. FR-4 substrate not only provides good heat dissipation performance, but also effectively reduces the failure rate of circuit boards caused by high temperature, ensuring reliability and stability.
FR-4 substrates are widely used in computers, communication equipment, industrial control and other fields. Whether in the control module of smart homes or in automotive electronic systems, FR-4 is everywhere, bringing convenience and high-tech experience to our lives.
Understanding the characteristics of FR-4 substrate can not only help you improve the efficiency of circuit board design and manufacturing, but also give your products an advantage in the competition. Let's explore the mystery of this amazing material together!
