Assembly Method for Direct Access Storage Device VLSI

       This article is based on the concept of integrating the
HDA (head disk assembly) electronic components in the board, in
particular the mother board, and to fix them by means of SMT (surface
mounted technology).

      Currently, hard magnetic storage devices are designed such that
the mechanical and electronic components (controller including power
supply) are built from single parts and integrated in a common
enclosure.

      The invention described in this article provides for the
mechanical components of the hard file to be separated from the
electronic ones; the electronic components (amplifier, controller,
power supply, servo means, etc.) are integrated in the board or
plug-in cards.

      The mechanical components are connected to the board by SMT
(see Figs. 1 and 2).  The electrical connectors for motor and
read/write element are arranged on the board, with connection being
established through solder paths.  The invention may be used to
advantage for hard drivers of 2.5, 1.8" and under, and to integrate
several such drivers as arrays and bulk storages.

      Fig. 2 is a sectional view of the mechanical components of a
hard file along with the board.  The mechanical components of the
hard file are connected to the board by solder points or pins.
