Abstract

Personal Computer Memory Card International Association (PCMCIA) cards are rapidly emerging as a standard for light-weight, portable electronic packages. The attractiveness of these cards, approximately the size of an ordinary credit card, lies in their small size, light weight and adherence to a standard which allows PCMCIA cards from one manufacturer to be plugged into connectors from another. PCMCIA cards are predicted to displace other designs in many applications using flash memory, DRAM, SRAM, ASIC's, magnetic media, etc., including portable computers, laptops and personal communication devices.

      Personal Computer Memory Card International Association
(PCMCIA) cards are rapidly emerging as a standard for light-weight,
portable electronic packages.  The attractiveness of these cards,
approximately the size of an ordinary credit card, lies in their
small size, light weight and adherence to a standard which allows
PCMCIA cards from one manufacturer to be plugged into connectors from
another.  PCMCIA cards are predicted to displace other designs in
many applications using flash memory, DRAM, SRAM, ASIC's, magnetic
media, etc., including portable computers, laptops and personal
communication devices.

      Pluggable I/O and memory expansion cards such as these,
however, are not designed and constructed to withstand the rigors of
operation in extremes of temperature, mechanical shock, vibration and
corrosive atmospheres such as might be experienced in a rugged
commercial, military or space application.  Such exposure typically
results in damage, and ultimately failure of critical semiconductor
components housed within the body of the card.

      These conditions reflect limitations of the current PCMCIA card
packaging.  For example, their sustained use in commercial or
military ground vehicles, ships and aircraft operating in hot or cold
climates would be precluded.  High humidity or chemically aggressive
atmosphere such as one would find at sea or in coastal regions would
also be unacceptable.  Under such conditions, an added level of
package integrity is required to meet the reliability objectives of
the system manufacturer, the card supplier, the user and PCMCIA.

      A solution to these limitations is a design for a ruggedized,
hermetically sealed version of the PCMCIA card.  It has application
to military, space and avionic electronic designs, but is not limited
