Abstract
Representative implementations of devices and techniques provide reinforcement for a carrier or a package. A reinforcement layer is added to a surface of the carrier, often a bottom surface of the carrier that is generally under-utilized except for placement of terminal connections. The reinforcement layer adds structural support to the carrier or package, which can be very thin otherwise. In various embodiments, the addition of the reinforcement layer to the carrier or package reduces warpage of the carrier or package.
