Abstract
A circuit that senses changes in the electrical characteristics of one or more solder joints, and generates one or more signals based, at least in part, on the electrical characteristics that are sensed, is incorporated into an integrated circuit. In a further aspect of the present invention, the one or more signals generated by the circuit are indicative of the reliability of the solder joints. Embodiments of the present invention provide a warning in advance of system failure, permitting repair or replacement of a failing unit/joint before a failure becomes catastrophic. Embodiments of the present invention include structures and circuitry that can determine whether solder joint failure has occurred, and that can communicate the occurrence of solder joint failure to other components or systems.
