As technology improving, people can put more and more copper layers on the same board. Our 94V0 4 Layer Fr4 PCB Board refers to printed circuit board has four copper layers.
The FR4 option on the PCB order page is the grade designation for the epoxy fiberglass that often form the PCB core and prepreg layers. It is the properties of this base that gives the PCB the electrical isolation and mechanical strength required to endure increasingly demanding applications.
By this structure, engineer can put trace on different layers for different purpose, such as layers for power, for signal transferring, for EMI shielding, for components assembly, and so on
-The fr-4 class provides excellent chemical resistance, flame retardant rating (ul94-v0) and electrical properties under dry and wet conditions.
- FR4 also has high bending resistance, impact resistance, excellent mechanical strength and bonding strength at temperatures up to 145 g10-fr4, which is suitable for structural, electronic, printed circuit board and electronic applications.
-Fr-4 is smart material due to a variety of mechanical and electrical properties; It is less reactive at high frequencies, which can absorb less moisture and has greater strength and stiffness.
Our 94V0 4 Layer Fr4 PCB Board can be widely used for Telecommunications, Sound and Vision Broadcasting, Opto-Electronics, Tank Electronics, Solar Photovoltaic Systems, Embedded Software, Industrial Automation and Control, Instrumentation, Medical, Telecom, UPS, DVD Player,Automotive, Access Media and Infomobility.
