Abstract
The sensor geometry for improved package stress isolation is disclosed. A counterbore on the backing plate improves stress isolation properties of the sensor. The counterbore thins the wall of the backing plate maintaining the contact area with the package. The depth and diameter of the counterbore can be adjusted to find geometry for allowing the backing plate to absorb more package stresses. Thinning the wall of the backing plate make it less rigid and allows the backing plate to absorb more of the stresses produced at the interface with the package. The counterbore also keeps a large surface area at the bottom of the backing plate creating a strong bond with the package.
