Resistance of pcb trace

    • 1. Introduction - Grainger College of Engineering | U of I

      The magnitude of the input resistance of these terminals is typically 109 to 1013 . Signal coupling problems occur when a trace that has a high impedance termination is next to a trace that has fast changing voltages, such as a digital or clock signal. In this situation, charge is capacitively coupled between the traces per the formula:

      In this case, trace impedance of 70 to 75 ( with a large enough trace spacing to keep crosstalk (especially reverse crosstalk) between PCB traces to a minimum is ideal. Place the termination resistors near the connector and select PCB trace impedance and termination resistance to sum to the cable impedance or slightly less.

      The trace and space widths are shown for standard manufacturing processes in copper conductor flex PCB. It is desired to keep the trace resistance below 4 ohms to preserve signal amplitude. The sensor output and clock trace pair impedance should be approximately 100 ohms but 63 ohms has been shown to work satisfactorily in a similar data path ...

By going back to PCB Express and taking a second look at the transmitter board design layout it was evident that the ground pins from the power supply were not traced to ground. We were able to fix this problem easily using alligator clips and ...

      The trace, when implemented into the PCB, should be made as short as possible. As seen above, the trace of choice was a coplanar waveguide. The coplanar waveguide utilizes the extra capacitance from the side conductors to increase the total capacitance, lowering the required width of the trace.
