Patent ID: 6933443

Claim:
An electronic device, comprising: a base comprising a pair of elongate flanges and a channel portion therebetween, the channel portion having a substantially planar first surface, wherein the pair of flanges extend generally perpendicularly from the first surface, and wherein the pair of flanges are separated by a predetermined channel width; a ceramic circuit board comprising a substantially planar second surface, wherein the second surface is substantially parallel to the first surface and operable to mate with the first surface within the channel width; and an adhesive layer generally residing between the first surface and the second surface, wherein the adhesive layer fixedly couples the first surface of the base to the second surface of the circuit board, wherein the pair of flanges are operable to substantially maintain the planarity of the first surface and the second surface during a thermal expansion or contraction of one or more of the base and the circuit board, wherein the base is associated with a first coefficient of thermal expansion and the circuit board is associated with a second coefficient of thermal expansion, and wherein the first coefficient of thermal expansion and the second coefficient of thermal expansion are dissimilar.
