Abstract: Strain sensing may be provided. First, a strain threshold for a circuit board may be determined. Then a strain capacitor may be selected that will fail when the circuit board is subjected to the strain threshold while the strain capacitor is mounted on the circuit board. The strain capacitor may be ceramic and may be in a commercially available size. The strain capacitor may then be mounted to the circuit board and monitored for failure.

Abstract: An apparatus may be provided. The apparatus may comprise a substrate and a circuit board. A ball grid array structure may be disposed between the substrate and the circuit board. In addition, a stand-off structure may be disposed between the substrate and the circuit board. The stand-off structure may be adjacent to the ball grid array structure.
