`
`1. A method {
`
`for operating
`
`system comprising component storages including
`
`a
`
`dry box for
`
`an electronic component mounting
`
`an electronic component from being exposed to moisture,
`
`
`preventing
`
`the method
`
`comprising:
`
`maintaining
`
`
`
`a material management table including
`
` ts information field for indicating whether
` t is stored in the dry box,
`an electronic component
`target indicator field for indicating whether an
`
`component is a moisture management target component,
`
`awhereabou
`
`
`
`
`
`a
`
`
`
`
`
`electronic
`
`and
`
`
`an exposure
`
`
`time field for indicating
`
`an exposure time
`
`during the moisture management target component has been in an
`
`atmospheric exposure state;
`
`pausing counting the exposure time when
`
`
`
`the moisture
`
`Management target component is stored in the dry box;
`
`identi
`
`
`fying amoisture management target component of which
`
`the exposure time has met or exceeded an exposure limit time based
`
`on the whereabouts ini
`
` Formation table; and
`
`notii
`
`Fying
`
`the
`
`
`
`identified moisture management
`
`target
`
`component
`
`to an appara
`
`
`
` CUS.
`
`
`2. The method of
`
`claim 1,
`
`comparing the exposure time with the exposure limit time
`
`
`set for the moisture management target component; and
`
`31
`
`
`
`placing
`
`a reel unit of
`
`
`the moisture management
`
`target
`
`component in one of the keeping rack,
`
`
`the dry box,
`
`or the dryer
`
`based on the comparison result.
`
`3. The method of claim 1,
`
`
`
`wherein the identifying and the notifying
`
`
`checking-in of the electronic component into a
`
`
`are executed at
`
`component keeping
`
`area.
`
`4. The method of claim 1,
`
`
`
`wherein the identifying and the notifying
`
`setting of a reel of
`
`
`
`the electronic component
`
`
`
`are executed at
`
`to a feeder.
`
`
`
`5. Amethod for operating
`
`an electronic component mounting
`
`system comprising component
`
`storages
`
`including
`
`a
`
`dryer
`
`
`for
`
`dehumidifying moisture from an electronic component,
`
`
`
`the method
`
`comprising:
`
`maintaining
`
`a material management table including
`
`
`
`
`
`awhereabouts information field for indicating whether
`
`
`an electronic component is stored in the dryer,
`
`target indicator field for indicating whether an
`
`
`
`electronic component is a moisture management target component,
`
`a
`
`and
`
`
`an exposure time field for indicating
`
`
`
`an exposure time
`
`during the moisture management target component has been in an
`
`atmospheric exposure state;
`
`32
`
`
`
`decreasing the exposure time when the moisture management
`
`target component is stored in the dryer;
`
`
`
`identifying amoisture management target component of which
`
`the exposure time has met or exceeded an exposure limit time based
`
`on the whereabouts information table; and
`
`
`notifying the
`
`
`identified moisture management
`
`target
`
`component
`
`to an
`
`
`
`apparatus.
`
`6. The method of claim 5,
`
`
`
`wherein the identifying and the notifying
`
`
`checking-in of the electronic component into a
`
`
`are executed at
`
`component keeping
`
`area.
`
`7. The method of claim 5,
`
`
`
`wherein the identifying and the notifying
`
`setting of a reel of
`
`
`
`the electronic component
`
`
`
`are executed at
`
`to a feeder.
