Dear Jim:

IPC-A-610D Does not allow for class three for jumper wires to be inserted into a PTH which contains an existing lead. This is due to the potential CTE differences between the solder, jumper wire, lead and the barrel wall. Lots of different metals will likely cause a lot of stress in a Class 3 operating environment.
