Abstract:
1. A device, comprising: a current source for connecting to a printed circuit board and providing electrical power to the printed circuit board; a first Field Effect Transistor (FET) switch pack connected to a first terminal of the current source for connecting to a surface mount connector of the printed circuit board, the first FET switch pack comprising a first plurality of FETs; a second FET switch pack connected to a second terminal of the current source for connecting to the surface mount connector of the printed circuit board, the second FET switch pack comprising a second plurality of FETs; and a FET controller connected to the first FET switch pack and the second FET switch pack for connecting a first FET of the first plurality of FETs to a first region of the surface mount connector and connecting a second FET of the second plurality of FETs to the first region of the surface mount connector to supply current to the first region of the surface mount connector, wherein the FET controller is configured for supplying the current to the first region of the surface mount connector to produce at least one continuous heat signature characteristic of a property connected component.
