Hello
I have a PCB that a part of one of the high speed lines is not placed over the ground plane. the length is 1300 mils 
actually it’s LSB line of a high speed DAC (200MHz, 3.3V logic, the input capacitance of the DAC is 5pF). 
is there any solution to repair it?

as usual we have a 22 OHM resistor at the input of the line. can I replace 22 ohm with a 75 or 100 OHM resistor at the input of this line to reduce any ringing or overshoot? or can I scratch a part of this line and solder a 0402 resistor, for example here:

Thanks
