Power carrier with selective thermal performance

摘要

A microelectronic package comprising a circuit carrier having a power chip, an integrated circuit means, and thermal conduction means for carrying heat from the microelectronic package is provided. The thermal conduction means includes a first heat dissipation back plate means associated with the power chip and a second heat dissipation back plate means associated with the integrated circuit means. The heat dissipation back plate means are electrically isolated from each other and have different heat dissipation capacity.
