Abstract
An electronic packaging structure and method of forming thereof wherein the structure is constituted of a modular arrangement which reduces stresses generated in a chip, underfill, and ball grid array connection with a flexible substrate in the form of an organic material, which stresses may result in potential delamination due to thermally-induced warpage between the components of the modular arrangement.
