초록

In this paper, we show an optimal structure of impedance control in high density layouts ina high multilayers PCB. The impedance control in a high multilayers FR-4 PCB is very portant isue because a dielectric layer's thickness is very thin. Especially, odd mode impedance control is more difficult than characteristic impedance control in high multilayers PCB. So, we show an optimal structure of odd mode impedance control in that dielectric thickness is about 0.1mm with limited state and discuss multilayers PCB's for swich circuti pack and backplane in developing algorith scale ATM witching system in next time.
