Harry is talking about the primary connections for power to the lanes.
Conductive adhesive is important for repairs to the tape. Or if you run out of tape on a lane before you finish the loop. In these situations, you have to restart the taping from where you left off, and to do that, you need to start the new roll from underneath the end of the old roll, which makes conductive adhesive the only way to avoid making the connection by poking dozens of tiny holes in the overlap with a very sharp point. As always, nothing is as important as burnishing the tape again and again when you are installing it to insure long life.
