Abstract: An apparatus for drying the air inside of hermetically sealed electronic devices. The apparatus includes a desiccant part and an activation piece that is attached to the desiccant part. The desiccant part and activation piece are attached together and then covered, except for the portions where the two pieces are attached, with a polymer that has a low moisture vapor transmission rate, such as parylene. The apparatus may be added into an electronic device during assembly. The desiccant, or drying agent, is not activated, by removal of the activation piece, until prior to closure of the hermetically sealed electronic device.
