Impedance constraint multilayer PCB including normal TG( 130~140) impedance control multilayer PCB, middle TG(150) impedance control PCB, high TG(170 or above) impedance controlled PCB.
When producing impedance controlled printed circuit boards(PCB), PCB designer shall indicate which line will be impedance controlled and how much of impedance. PCB producer will check and examine if the impedance controled lines and layers stack can meet the targets.If layer stack can not meet the lines impedance, PCB producer will ask customers' oppinion to change the layer structure to meet the impedance requirments.
Usally impedance controlled/constraint PCB are used to communication applications or other applications with signal requirement.
