Abstract
An information handling system circuit board has an opening formed through it proximate a coupling point of an integrated circuit to the circuit board. The opening manages stress at the coupling point of the integrated circuit to the circuit board to reduce the risk of damage to the coupling point during deformation of the circuit board, such as when the circuit board is coupled to a chassis or when a component is pressed into the circuit board. In one embodiment, rectangular openings are formed at diagonally opposed corners of a BSA integrated circuit. In alternative embodiments, openings of varying shape, such as slots or curved slots, are formed at selected corners of the integrated circuit.
