The right way of impedance controlled method

HTD PCB manufacturer expert told you the right way of impedance controlled method.


In our TV/satellite cable example the antenna is the source, the TV the load and the coaxial cable the conductor.  The cable has conductors and insulators and the dimensions of these along with their electrical characteristics are measured to carefully control the electrical impedance of the cable. If we want the signals in our PCB to

transfer along the path from a signal source to a load via a conductor or track efficiently, we need to control impedance. So what can I do to control impedance?

For the signal to get from the source to the load the impedance’s along the line must match. Therefore, the output impedance of the source, the impedance of the track and the input impedance of the load must match.
