1. A submount for a light emitting device package, comprising:

  • a generally rectangular substrate having a first surface and a second surface opposite the first surface, a first end and a second end opposite the first end;

    a first bond pad on the first surface of the substrate, wherein the first bond pad includes a die attach region offset toward the first end of the substrate and configured to receive a light emitting diode thereon;

    a second bond pad on the first surface of the substrate, wherein the second bond pad includes a bonding region that is between the first bond pad and the second end of the substrate and a second bond pad extension that extends from the bonding region along a side of the substrate toward a corner of the substrate at the first end of the substrate; and

    first and second solder pads on the second surface of the substrate, wherein the first solder pad is adjacent the first end of the substrate and the second solder pad is adjacent the second end of the substrate, and wherein the second bond pad is in conductive electrical contact with the first solder pad by means of a first electrical trace on the substrate extending from the second bond pad extension to first solder pad and the first bond pad is in conductive electrical contact with the second solder pad by means of a second electrical trace on the substrate extending from the first bond pad to the second solder pad.
