3 Layer HDI Impedance Control PCB

For the impedance Control PCB,We may change trace width/space or stackup ,but please do not worry, if any changes,we will send you to approve before proceeding. Generally,the tolerance is 10%,and more accurate is 8% .All impedance boards ,we will test here and report.This design is 3 layer HDI impedance control PCB and HDI PCB.
