`ABSTRACT
`
`Provided is a method for operating
`
`an electronic component
`
`mounting system including component storages including
`
`a
`
`drybox.
`
`The method includes maintaining
`
`a material management table
`
`including
`
`
`a whereabouts information field for indicating whether
`
`
`
`
`
`an electronic component is storedinthe drybox, atarget indicator
`
`
`field for indicating whether an electronic component is amoisture
`
`
`
`
`
`Management target component, and an exposure time field for
`
`
`
`
`
`indicating
`
`an exposure time during the moisture management target
`
`component has been in an
`
`atmospheric exposure state. The method
`
`also includes pausing counting the exposure time when the moisture
`
`
`
`
`Management target component is stored in the dry box, identifying
`
`a moisture 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.
