You may wish to break the target section apart from the main capture board. This can easily be accomplished by following these instructions:

  1. Using a sharp knife (such as Xacto knife or retractable safety knife), cut the traces on the bottom side of the board along the cut line. Pass the knife back and forth several times. Scoring the board deeply will make the breaking process easier and less stressful on the PCB:


  2. Score the board on the top side:
