Abstract
An electronic device package includes a portion that functions as a membrane to allow small molecules, such as gas molecules, to relatively freely traverse the housing boundary, while simultaneously substantially preventing large molecules, such as liquid molecules, from entering the confines of the housing. As a result, the package can be readily used in reflow processing without risking damage to the boundary integrity between the housing and the support surface that supports both the electronic device and the housing.
