Re: PD Board Legality Question

Mathew,
Teams who have damaged the PD in this same fashion have found that a careful drill and tap of the post will give them back the use of the PD. I believe a 1/4-20 would be appropriate, although a 1/4-28 might be a better hold. It is not possible to replace the terminal post. It is force fit into the PD circuit board and is held in place by the 25 pins on the back of the post. (the wave solder is only secondary to the connection) When drilling you must be careful not to drill so deep that you break the contact with these pins. You must use a bottom tap to get threads all the way to the bottom of drilled hole. Be careful that chips from the drill and tap operation do not get into the electrical parts on the PD. I would also recommend that this PD be used only on practice bots in the future and that a replacement be obtained when you can.
