Card Level Programming of Eproms Requiring Ultra-Violet Light

      A technique for programming EPROMs at the card level through
the utilization of a special card connector is disclosed.

      To facilitate device personalization, current card fabrication
methods utilize a socket for EPROMs which may be removed for
programming purposes. Through the use of an additional set of card
tabs or other connection means which can be utilized to personalize a
EPROM, direct chip attachment is facilitated, eliminating the need
for personalization at the component level.  This allows EPROMs
containing micro-code for any application to be attached to a carrier
or card and be personalized at the next level of assembly. Also, a
savings in socket inventory, card area required for EPROMs, and
additional assembly steps required in manufacturing is realized.

      The card level EPROM programming approach works well in a wire
bond assembly and can be extended to solder ball chip mounting
techniques through the addition of a quartz window over the active
chip area.
