Patent ID: 8115106

Claim:
A surface mount electronic device comprising: a circuit board including at least one conductor pattern located adjacent an insulating board, the conductor pattern including both a die bonding pad and at least one wire bonding pad that extend to respective electrodes for receiving power supply, the die bonding pad having both a center and a circumference, and the die bonding pad including a plurality of cutout sections that expose the insulating board and extend towards the center of the circumference; and an electronic component having both a bottom surface and a center of the bottom surface and being mounted on the die bonding pad with an adhesive material, and further including electrodes that are electrically connected to each respective electrode of the conductor pattern through at least one of the die bonding pad via the adhesive material and the at least one wire bonding pad via at least one bonding wire, wherein the plurality of cutout sections is not formed underneath the bottom surface of the electronic component, and the adhesive material contacts a portion of the insulating board exposed in the plurality of cutout sections located out of range of the bottom surface of the electronic component mounted on the die bonding pad.
