Electronic Packaging Technology for Personal Computer Memory Card
International Association Disk Files

      Several electronic packaging technology for Personal Computer
Memory Card International Association (PCMCIA) Type 2 disk files are
disclosed to provide a means for packaging the disk file electronics
in a height of about 1.0 mm.

      A multilayer flexible carrier is utilized as a board instead of
a conventional hard board.

      The Arm Electronic (AE) cable and the motor cables are
integrated into the multilayer flexible carrier by those cables being
an extension of one of the layers of the multilayer carrier.

      The multilayer flexible carrier is further attached to the disk
file cover.  The cover provides a rigid platform for wirebond and/or
Direct Chip Attach (DCA) mounting of the electronic components to the
multilayer flexible carrier.

      The disk file cover also serves as a heat sink for electronic
components on the multilayer carrier.

      To further reduce the height, electronic components are mounted
in recessed holes in the multilayer carrier.

      The carrier, being flexible, can be bent to mate with the
PCMCIA connector.

      The above packaging technique provides a disk file with fully
integrated cables that require no additional connectors other than
the PCMCIA connector.
