Ro4350B+FR4 hybrid Board with quick ship time

What is Rogers 4003c?

Roger 4003 printed board the materials used are proprietary woven glass reinforced hydrocarbon/ceramics with the electrical performance of PTFE/woven glass and the manufacturability of epoxy/ glass. ... Unlike PTFE based microwave materials, no special through-hole treatments or handling procedures are required.

Roger 4350 printed board has a low coefficient of thermal expansion: The coefficient of thermal expansion (CTE) of RO4000 series materials also brings many benefits to PCB  circuit designers. Since its thermal expansion coefficient is similar to that of copper, it can provide excellent dimensional stability. This is particularly important for multilayer circuit design. Even in severe thermal shock applications, the low Z-axis CTE expansion coefficient of RO4000 series materials ensures the quality of the through holes in the board.
Rogers RO4000 high-frequency board has a wide range of applications: it can be used for satellite TV LNB, microstrip lines, cellular base station antennas and power amplifiers,and Etcspectrum communication systems, RFID tags, etc.
