Claim:
1. A method for evaluating the bond between an inertial sensor and a substrate, comprising the steps of: fixing a first electrically conductive bonding pad to said inertial sensor; fixing a second electrically conductive bonding pad to said substrate; splitting one of said first electrically conductive bonding pad and said second electrically conductive bonding pad into at least first part and second part so as to have electrical discontinuity between said first part and said second part; forming an electrically conductive bond between said first electrically conductive bonding pad and said second electrically conductive bonding pad such that electrical continuity is established from said first part of said one of said first electrically conductive bonding pad and said second electrically conductive bonding pad, through the other said first electrically conductive bonding pad and said second electrically conductive bonding pad, and through said second part of said one of said first electrically conductive bonding pad and said second electrically conductive bonding pad; and testing electrical continuity between said at least two parts so as to thereby evaluate the integrity of the electrically conductive bond; and forming multiple pins around the edges of a leadless chip carrier for electrical connection to other components on said substrate, and connecting a microprocessor device to said inertial sensor pins, wherein the inertial sensor is packaged in said leadless chip carrier, and wherein said step of fixing said first electrically conductive bonding pad to said inertial sensor comprises the step of fixing said first electrically conductive bonding pad to said inertial sensor such that said pad is at least partially located on the bottom surface of said leadless chip carrier between said edges.
