Abstract

Disclosed is a system that automatically handles, programs, labels, tests and sorts programmable devices called ROMKEYS. ROMKEYS are comprised of an eight leaded chip that is mechanically staked to a plastic carrier. The configuration of the system has been made as robust as possible to allow for adaptability to the many programmable devices that exist. Please refer to the Figure. The parts can be fed into the machine in bulk through a vibratory bowl feeder or through carriers, i.e., plastic tubes. As each part is fed along a handling track, the part is tested for mechanical defects, i.e., bent chip leads, plastic molding flashing, etc. The ROMKEY is then oriented and programmed through small probes. The parts are then retested for programming defects.

Automated System for Programmable Devices

      Disclosed is a system that automatically handles, programs,
labels, tests and sorts programmable devices called ROMKEYS.  ROMKEYS
are comprised of an eight leaded chip that is mechanically staked to
a plastic carrier.  The configuration of the system has been made as
robust as possible to allow for adaptability to the many programmable
devices that exist.  Please refer to the Figure.  The parts can be
fed into the machine in bulk through a vibratory bowl feeder or
through carriers, i.e., plastic tubes.  As each part is fed along a
handling track, the part is tested for mechanical defects, i.e., bent
chip leads, plastic molding flashing, etc.  The ROMKEY is then
oriented and programmed through small probes.  The parts are then
retested for programming defects.

      The system automatically sorts out parts that are either
mechanically defective or have programming errors and discards them.
Acceptable parts are then labelled through several approaches.
Labels may be applied by transfer printing methods, laser printing,
or ink jet technology.  The detail required by the label and the
through-put of the system have strong influences over the labeling
approach that is chosen.  The labels of the parts are inspected and
sorted before the ROMKEYS are finally loaded into carriers to leave
the machine.  The programming, testing printing, and inspection of
the parts are all easily changed through the machine's software...
