Abstract:
1. An electronic package comprising: a circuitized substrate including a first surface with a first and second portion thereon, said substrate having a first stiffness; a plurality of electrically conductive circuit members positioned on said first portion of said first surface of said circuitized substrate, each of said plurality of electrically conductive circuit members adapted for having solder connections thereon and for being electrically connected to a semiconductor chip; and a stiffener layer having a second stiffness positioned on said second portion of said first surface relative to said first portion, said second stiffness of said stiffener layer distributing a portion of said first stiffness of said circuitized substrate so as to substantially prevent failure of said solder connections between said electrically conductive circuit members and said semiconductor chip during operation of said electronic package, wherein said circuitized substrate includes a layer of adhesive positioned on at least a portion of said second portion of said first surface of said circuitized substrate to adhere said stiffener layer to said first surface.
