摘要

A flexible substrate having a first side and a second side may be provided. A device may be electrically connected to the first side of the flexible substrate through one or more electrical connections. A warpage control device may be attached to the second side of the flexible substrate. The warpage control device may include an adhesive layer and a rigid layer. The warpage control device may be formed in an area on the second side of the flexible substrate that may face the electrical connections on the first side of the flexible substrate.
