High-speed Connector is a critical component in high-speed serial system,whose skew directly affects the system's performance. A Method to obtain skew based on Impulse response of Insertion Loss and Return Loss is introduced. Combined with a simple mathematical subtraction,the accurate measurement data of high-speed Connector's skew can be extracted by totally removing fixture's influence. Meanwhile, a new mix lamination is adopted to lower PCB trace's skew.With which the fixture's skew is reduced to guarantee the accuracy of measurement S parameter of connector.


With this method,we can totally remove the skew of fixtures, Also a new stackup is adopted to reduce skew of PCB trace .without any specific limitation.
