First Claim
Patent Images
1. A method comprising:
- identifying a failure profile of solder joints formed between a first component and a level of interconnects and between the level of interconnects and a second component; and
disposing a reliability cover over one or more surfaces of at least one of the first component and the second component based upon the failure profile,wherein the reliability cover comprises a package level reliability cover that is disposed on at least a portion of an integrated circuit package, and wherein a second reliability cover comprises a die level reliability cover that is disposed on at least a portion of a die.

Abstract
A reliability cover that is disposed over at least one of an integrated circuit package and a Si die of the integrated circuit package is disclosed. The integrated circuit package is mountable to a printed circuit board via a plurality of solder balls. The reliability cover is configured to reduce a difference in a coefficient of thermal expansion between the integrated circuit package and the printed circuit board, and between the Si die and a substrate of the integrated circuit package by a threshold value.
