    Abstract: An instrument cluster for communicating a vehicle's operating status to a vehicle occupant is disclosed. The instrument cluster includes a housing for supporting the instrument cluster. The housing is mountable to a vehicle instrument panel. A circuit board is secured to the housing. A motor having a motor shaft is rotatably coupled to the motor and the motor is secured to the circuit board. A gauge pointer is mounted on the motor shaft and rotatable therewith for indicating the vehicle's operating status. At least one diode is provided for illuminating the gauge pointer and at least one diode “footprint” is disposed on the circuit board proximate the motor shaft for electrically interconnecting the at least one diode to the circuit board. The at least one diode “footprint” has a cathode solder pad and an anode solder pad. The anode solder pad is substantially rectangular and the cathode solder pad is substantially L-shaped.

    Abstract: A method and apparatus is provided that pertains to resisting crack initiation and propagation in electrical interconnections between components and substrates in ball grid array microelectronic packages. A hybrid of dielectric defined and non-dielectric defined electrical interconnects reduces the potential for electrical interconnection failure without having to control the dielectric defined interconnect ratio of substrates. In addition selective orientation of the dielectric defined edge portion of the electrical interconnect away from the point where cracks initiate resists crack propagation and component failure.
