how to impedance control pcb build
Dear all,
Could anyone teach me that how do you do the impedance control (RF trace width) on the mass PCB production? It is because I have not much experience on the RF trace impedance control on the mass PCB production.
As I am doing in research, I just calcuated the width on the RF trace (50ohms trace) and then make it on the PCB directly. However, how could I do the impedance control on the mas PCB in order to make sure that the board variation is not so large? Morevoer, what is the acceptable error percentage? +/-10% or less?
Thanks
