The Importance of Impedance Control in PCB design (and how to avoid Signal Integrity problems)

What is Impedance Control and Signal Matching Impedance control is matching PCB trace dimensions and locations with the properties of the substrate material to make sure that the strength of a signal traveling along a trace is within a required range. The continual increase in device switching speeds is confronting engineers with signal integrity(SI) problems and eventually, most devices are going to have to deal with SI issues. So, Printed Circuit Board(PCB) traces can no longer be treated as a simple point-to-point connection. Traces need to be considered as transmission lines and impedance matching becomes necessary to lessen or eliminate the impact on SI. By following good design practices and approaches, many potential signal integrity issues can be averted or mitigated. So, here we’ll talk […]
