    Abstract: In the present invention there is disclosed an electronic package assembly (10) wherein an electronic device (18) (for example a chip) on a circuitized substrate of the package assembly (10) is thermally coupled to a heatsink (22) in a separable manner using a plurality of compressible, thermally conductive members (26) (for example solder balls). These members (26) are compressed and permanently deformed as part of the thermal coupling. Disclosed is also a process for producing such electronic package assembly, which process comprises manufacture of a substrate with conductors placed thereon, placing an electronic device on such circuitized substrate and connecting thereof to the conductors, thermal coupling of a heatsink to the electronic device in a separable manner, placing compressible, thermally conductive members between the electronic device and the heatsink and exerting compressible force on this package assembly.

    Abstract: An electronic package and method of making same in which a circuitized substrate having a first stiffness includes a plurality of electrically conductive circuit members on a first portion of the circuitized substrate and is adapted for having solder connections thereon and for being electrically connected to a semiconductor chip. A stiffener layer having a second stiffness is positioned on a second portion of the circuitized substrate relative to the first portion, the second stiffness of the stiffener layer distributing a portion of the first stiffness of said circuitized substrate so as to substantially prevent failure of the solder connections between the electrically conductive circuit members and the semiconductor chip during operation of the electronic package.
