Abstract
A flanged stiffener ring for device packages/electronic devices includes flanges protruding from the sides of the stiffener ring body. The flanged stiffener ring is of minimal material to keep weight low, but maintain rigidity and, thus provide stiffening forces to a substrate of the device package to inhibit substrate warpage.
