Why are meander route used
Why are meander route used on PCB ?
Often on circuits that work with high frequency, such as computer motherboards or cell phones, meander paths are seen on the PCB.
These paths are often seen in three ways:
1) The first mode is accordion
2) The second mode in the form of trombone
3) The third mode is in the form of a saw tooth
These paths are used for impedance and delay matching, of course, at frequencies above 10 GHz. In circuits where signals are moving at a high frequency, around gigahertz, if we cannot deliver the signals to the destination simultaneously, the wrong value will be received at the destination and will cause an error in the circuit. These routes are used for this purpose. Of course, noise sensitivity is one of the other reasons.
In this video, we will examine this issue and I will show you an example at the end of the video.
Of course, my signal generator cannot produce gigahertz frequency, that's why this test is only for the amplitude reduction , not the delay
Sorry, I don't have the right tools for this test
