An apparatus and method for controlling movement of packaged devices. Specifically, embodiments of the present invention discloses an apparatus a method of providing a controlling mechanism for effecting physical control over a device that is disposed on a structure. An exothermically reactive structure is disposed on the controlling mechanism, such that, when activated, an exothermic alloying reaction between alloys in the exothermically reactive structure operates the controlling mechanism. The controlling mechanism is adapted to release the device, position the device, or tune the device.
