Hi,
I am designing a PCB substrate (FR4 with 1mm thickness) to place 4 pads chip on top, and then it has a thru hole connect to the bottom layer of the PCB, and the PCB will be mounted on a flex circuit.
What is the best way in controlling the impedance of the PCB substrate since it do not have traces (only pads with via holes) while ensuring its signal integrity on high speed?
Thank you and hope that someone can help in this matter.
