Abstract

A program is described which controls the packaging of decoupling capacitors (DCAPs) into a linear device bank (LDB) or to a reel-to-reel tape depending on customer need. The program is used in a special-purpose tool controlled by an IBM AT* personal computer. The tool includes optical sensors which perform mapping functions and a pick head which transfers DCAPs from incoming carriers to the LDB or tape.

Decoupling Capacitor Linear Data Bank/Tape Load Program

       A program is described which controls the packaging of
decoupling capacitors (DCAPs) into a linear device bank (LDB) or to a
reel-to-reel tape depending on customer need. The program is used in
a special-purpose tool controlled by an IBM AT* personal computer.
The tool includes optical sensors which perform mapping functions and
a pick head which transfers DCAPs from incoming carriers to the LDB
or tape.

      The program first commands the optical sensors to  map the
incoming carrier which holds the DCAPs.  Based on the data gathered,
it then tells the pick head, which has four positions, to pick only
the positions with the devices and to skip blanks.  Thus, there will
be no blanks in the LDB or the tape.  During the pick process, the
next product carrier is being mapped by the optical sensors.

      When loading devices to the LDB, the pickhead and the LDB are
indexed by an index table driven by DC motors to position the device
in the appropriate cavity.  The devices must be placed individually
as the spacing between the cavities in the LDB does not align with
the pickhead spacing.

      When loading devices to the tape, the pick head preferably
places four devices simultaneously.  This can be accomplished since
the spacing between cavities on the tape is exactly the same as the
spacing on the pick head.  In other embodiments of the tool, the
spacing of the pick head may be identical...
