ABSTRACT:
There is provided an electronic package assembly having a leadframe and buffer bonded to a metallic base. To reduce the stress generated by the coefficient of thermal expansion mismatch, the buffer is mounted on a pedestal. The cross sectional area of the pedestal is less than that of the buffer, such that the at least a portion of the buffer overhangs the pedestal.
