FR4 PCB is a very common and important basic material in the electronics industry. Its full name is glass fiber reinforced epoxy resin copper clad laminate.
FR4 material has excellent electrical insulation properties, effectively isolating different parts of the circuit and preventing short circuits. At the same time, it also has good mechanical strength, able to withstand certain external impacts and vibrations, ensuring the stability and reliability of the circuit board. Furthermore, FR4 PCB has excellent heat resistance, maintaining stable performance in high-temperature environments and is not easily deformed or damaged.
