High Frequency PCB Rogers 60mil 1.524mm RO4350B Double Sided RF Circuit Board Patch Antenna PCB
RO4350B material possesses the properties needed by designers of RF microwave circuits and matching networks and controlled impedance transmission lines. Low dielectric loss allows RO4350B material to be used in many applications where higher operating frequencies limit the use of conventional circuit board materials.
The temperature coefficient of dielectric constant is among the lowest of any circuit board material, and the dielectric constant is stable over a broad frequency range.
RO4350B material's thermal coefficient of expansion(CTE) provides several key benefits to the PCB designers. The expansion coefficient of RO4350B is similar to that of copper which allows the material to exhibit excellent dimensional stability, a property needed for mixed dielectric multi-layer boards constructions.
The low Z-axis CTE of RO4350B provides reliable plated through-hole quality, even in severe thermal shock applications. RO4350B material has a Tg of >280C so its expansion characteristics remain stable over the entire range of PCB processing temperatures.
