Memory card e.g. secure digital memory card, cap structure, has flash memory wafer whose lower part is electrically connected with connection part of base, and detention layer provided between base and frame of housing

摘要

The structure has a flash memory wafer (2), and contacts electrically connected with contacts of a connection part of a base (1), where a lower part of the wafer is electrically connected with the connection part. A housing has a frame, and a metal plate lies in the center of the frame, so that the housing has a hollow space for a wafer controller that includes a passive module and the wafer. A detention layer is provided between the base and frame, where both sides of the layer are respectively bonded to an edge of the base and a surface of the frame.
