发明名称 Package warpage control
摘要 A method of packaging includes placing a restrainer on a package during processing. The method includes clipping the restrainer in place and then exposing the package to high temperatures. After processing the restrainer is removed. An alternative process attaches a component die to a substrate having a cavity in a first surface. The process may then include dispensing and curing an underfill material in the cavity, and attaching a lid to the first surface of the substrate.
