4350B PCB is a high performance printed circuit board material known for its excellent electrical and thermal properties. Below are some key properties and application areas regarding 4350B PCB:

Dielectric Constant: 

Rogers 4350B has a dielectric constant of 3.48, which is lower than FR4 materials commonly used in the PCB industry. This means that it has a lower electromagnetic wave propagation velocity, which helps to reduce signal transmission delays and increase the speed and efficiency of signal transmission.

Dielectric Constant Tolerance: 

4350B has a lower dielectric constant tolerance, which means that the dielectric constant has a smaller range of variation. This helps the material to have a better microstructure with fewer internal defects and impurities, thus providing stable dielectric properties.

Coefficient of Thermal Expansion: 

RO4350B has a very low coefficient of thermal expansion of 32 ppm/°C in the Z-axis direction. This helps to maintain the stability of the PCB structure during temperature changes, reducing thermal stress and preventing stress buildup and damage inside the PCB due to temperature changes.

CAF Impedance: 

CAF (conductive anode electrochemical migration) impedance is an excellent feature of the Rogers RO4350B that prevents current leakage and short circuits, reducing equipment damage and repair costs due to electrical failures.

Adaptability to Mass Production: 

The 4350B HF sheet can be adapted to conventional PCB manufacturing techniques without the need for special pre-treatment processes such as plasma treatment of PTFE sheets or any other additional processes.

Application Areas: 

Due to its excellent dielectric constant, coefficient of thermal expansion, and CAF impedance, 4350B is very popular in the HF telecom field and is used in a wide range of applications such as cellular base station antennas, power amplifiers, microwave point-to-point connectivity, automotive radar and sensors, RFID tags, and HF headers for direct broadcast satellites.

Manufacturer Information:
