The Advantages of Using FR4 Material for PCB Production

FR4, a type of composite material based on glass fiber and epoxy resin, is commonly used as the main substrate material in PCB manufacturing. Its main advantages include:

1. High mechanical strength: FR4 has excellent mechanical strength and hardness, and can withstand certain forces such as tension, compression, and bending.

2. Good insulation performance: Due to the high insulation performance of epoxy resin, the insulation performance of FR4 substrate is also very good, effectively preventing short circuits between circuit boards.

3. Good temperature resistance: FR4 can withstand high temperatures, generally up to 150℃ or more.

4. Good processability: FR4 has good processability and can be drilled, cut, and perforated.

Due to its superior performance, FR4 material is widely used in various fields, including communications, computers, medical equipment, transportation, aerospace, and military equipment.
