Abstract

The invention discloses a ceramic bonding pad array shell and belongs to the technical field of ceramic shells of integrated circuits. The ceramic bonding pad array shell comprises a ceramic substrateand a T-shaped heat sink, wherein a cavity with steps is formed in the middle of the ceramic substrate; the upper surface of the heat sink is used for mounting chips; the heat sink is in matched overlap connection with the cavity; and the lower surface of the heat sink is co-planar to the lower surface of a bonding pad arranged on the lower surface of the ceramic substrate. According to the ceramic bonding pad array shell disclosed by the invention, the technical problems existing in the prior art that alignment of ball placement or column placement molds is influenced by the ceramic bondingpad array shell, air convection is influenced and heat dissipation is bad can be solved. The technical effects that alignment of ball placement or column placement molds is not influenced, ball placement or column placement can be performed on the surface of the heat sink and the heat dissipation ability is improved can be achieved.

Description

technical field [0001] The invention belongs to the technical field of integrated circuit ceramic shells, and more specifically relates to a ceramic pad array shell. Background technique [0002] The ceramic shell is developed on the basis of multilayer ceramic technology and ceramic-metal sealing technology, and is an important support for integrated circuits. Its basic functions include: 1) realize the mechanical support for the chip; 2) realize the isolation between the chip and the external environment; 3) realize the electrical signal connection between the chip and the external circuit; 4) realize the heat dissipation path of the chip. [0003] The electronic component housing refers to the package of the component, and its main function is to provide electrical (optical) signal interconnection, mechanical protection, environmental protection, and heat dissipation. In the field of high reliability and high performance applications, the ceramic shell based on alumina c...
