In an embodiment, a device includes: an integrated circuit die; a redistribution structure over a front-side surface of the integrated circuit die; a socket over the redistribution structure; a mechanical brace over the socket, the mechanical brace having an opening exposing the socket, edge regions of the socket overlapping edge regions of the mechanical brace at the opening; a first standoff screw disposed in the edge regions of the mechanical brace, the first standoff screw physically contacting the socket, the first standoff screw extending a first distance between the socket and the mechanical brace; and a bolt extending through the mechanical brace and the redistribution structure.
