1. Optical modules are crucial components in optical fiber communications, and they transmit high-frequency signals such as 1G, 10G, and 100G.
2. In optical fiber communication applications, optical modules are small in size but generate large amounts of heat.
3. Therefore, the PCB material for optical modules must meet high-speed requirements and have excellent electrical and mechanical properties.RO4350B is a glass fiber reinforced hydrocarbon/ceramic laminate sheet with a dielectric constant of 3.48 and a loss factor of 0.0031, ensuring the transmission of high-frequency signals and reducing signal attenuation. It has one of the lowest dielectric constants with temperature fluctuation among similar materials, at only 50ppmC.
With a coefficient of thermal expansion (CTE) similar to that of copper, RO4350B provides excellent dimensional stability, crucial for multilayer circuit board design. Even in severe thermal shock applications, the low Z-axis thermal expansion coefficient of RO4350B (only 32ppm/C) ensures the quality of through holes in the board.
