An electronic module includes a substrate including at least one structure that reduces stress flow through the substrate, wherein the structure includes at least one trench in a surface of the substrate, and a plurality of capacitor legs disposed on an upper surface of the substrate.

Electronic components on trenched substrates and method of forming same

An electronic module including a substrate having at least one structure that reduces stress flow through the substrate, wherein the structure comprises at least one trench in a surface of the substrate.

A method of mounting an electronic component on a substrate includes forming at least one trench in a surface of the substrate. The trenches formed in the substrate reduce a stiffness of the substrate, which provides less resistance to shear. Accordingly, the trenches reduce the amount of strain on the joints, which mount the electronic component to the substrate, which enhances the life of the joints.
