A device may include a current source for connecting to a printed circuit board. The device may also include a first FET switch pack and a second FET switch pack for connecting to the surface mount connector of the printed circuit board. Additionally, the device may include a FET controller connected to the first FET switch pack and the second FET switch pack. The FET controller may be utilized for connecting a first FET and a second FET to the first region of the surface mount connector. The FET controller may be configured for supplying the current to the first region of the surface mount connector to produce at least one continuous heat signature characteristic of an improperly connected ground pin. A thermal monitoring module may be used to identify the improper physical connection.
