`
`it is extremely important
`
`
`to properly manage such a
`component
`
`
`
`
`inventory in reducing production costs. Because of this, efforts
`
`to systematize inventory management by individually identifying
`

`
`
` An embodiment of the invention will hereinasFrer be described

`
`
`
`1 of an embodiment of the invention.
`
`
`
`The electronic component
`
`mounting system 1 mounts an electronic component ina substrate
`
`and produces
`
`a
`
`mounting substrate.
`
`As
`
`shown in Fig.
`
`1,
`
`the
`
`electronic component mounting system 1
`
`includes a component
`
` mounting line la,
`a member management part 4 and a
`
`system 3,
`
`a communication network 2,
`
`a line management
`
`
`
`storage part 5.
`
`The
`
`
`component mounting line la is configured to couple
`
`a substrate
`
`supply apparatus M1,
`
`a substrate delivery apparatus M2,
`
`a solder
`
`printing apparatus M3,
`
`a first electronic component mounting
`
`
`apparatus M4,
`
`a second electronic component mounting apparatus
`
`M5, a reflow apparatus Mo and a substrate recovery apparatus M7
`
`
`in series.
`
`[0012]
`
` In component mounting work by the component mounting line
`
`la,
`
`a substrate supplied by the substrate supply apparatus M1 is
`
`carried into the solder printing apparatus M3 through the substrate
`
`deliveryapparatusM2. Thesolderprinting apparatus M3 does screen
`
`
`
`printing of solder for component bonding
`
`on the substrate.
`
`The
`
`substrate after the screen
`
`
`
`
`printing is sequentially delivered to
`
`
`
`
`the first electronic component mounting apparatus M4 and the second
`
`electronic component mounting apparatus M5.
`
`The first electronic
`
`component mounting apparatus M4 andthe secondelectronic component
`
`mounting apparatus M5
`
`install an electronic component
`
`on the
`
`
`
`
`
`substrate after the solder printing. The substrate on which the
`
`
`
`component is installed is carried into the reflow apparatus M6.
`
`The
`
`
`reflow apparatus M6 heats the substrate according to a
`
`
`
`
`
`
`
`predetermined heating profile.
`
`
`The solder for component bonding
`
`
`is melted and solidified by the heating. Finally,
`
`
`
`the mounting
`
`substrate in which the electronic component
`
`is mounted in the
`
`substrate is recovered by the substrate recovery apparatus M7.
`
`
`
`[0013]
`
`
`
` Before the work by the component mounting line la described
`
`above,
`
`an electronic component to be mounted is dispatched from
`
`
`a
`
`component keeping
`
`area 6 and predetermined setup work for use
`
`in the component mounting line la is done in an external setup
`
`area 7andthen the electronic component is suppliedto the component
`
`mounting line la.
`
`
`
` In the present embodiment,
`
`the electronic
`
`
`
`component in a state housed by being held in a carrier tape and
`
`wound on a reel 8 (see Fig. 2) is targeted. After the reel 8 taken
`
`
`area 6 is set ina tape feeder 9 (see
`
`
`
`out of the component keeping
`
`Fig. 2) constructing
`
`a
`
`component supply unit in the external setup
`
`
`
`area 7,
`
`
`the reel 8 is supplied to the first electronic component
`
`
`mounting apparatus M4 or the second electronic component mounting
`
`
`apparatus M5 of
`the component mounting line la.
`
`
`
`
`
`components left after executionof predetermined component mounting
`
`
`again detached from the tape feeder 9 and are returned
`
`
`Unconsumed
`
`
`
`work are
`
`tothe component keepingareasé. Thatis, inthepresent embodiment,
`
`
`
`
`the first electronic component mounting apparatus M4 and the second
`
`
`electronic component mounting apparatus M5 are
`
`configuredto supply
`
`the electronic component
`
`through the component
`
`supply unit
`
`constructed so as to set the reel
`
`8
`
`
`in the tape feeder 9.
`
`[0014]
`
`
`
`
`
`Each apparatus included in the component mounting line la
`
`1s
`
`connected to the line management
`
`system 3
`
`through the
`
`communication network 2.
`
`The linemanagement system3 is connected
`
`to the storage part 5 and the member management part 4 of a system
`
`
`
`
`
`management computer for
`performing centralized control of
`
`the
`
`electronic component mounting systeml.
`
`Themember management part
`
`4 pert
`forms processing necessary
`
`for member management including
`
`
`
`component keeping
`
`area 6.
`
`
`
`
`each work of acceptance, dispatch and return of the reel 8 to the
`
`The storage part 5 stores information
`
`
`for each processing by the member management part 4.

`
`
`
`In the electronic component mounting system 1,
`
`
`the reel

`t
`
`
`information
`
`8 used in the component mounting work includes
`
`
`
`
`
`whereabouts information
`for specifying
`
`a whereabouts location.
`
`The ini
`
`
`
`Formation about the reel 8 is managed by the member management
`
`part 4 and is recorded on the storage part 5.
`
`That is, whereabouts
`
`
`information about the reel 8 in the component keeping
`
`area 6 or
`
`the external setup
`
`area 7 is transmitted to the member management
`
`part

`
`As shown in Fig. 2, themember management part 4 has a check-in

`
`an external setup processing part 13 and an
`
`exposure time management part 14 as internal processing functions,
`
`
`and further has a receiver 15.
`
`
`The receiver 15 receives data sent

`
`record processing in the case where the component keeping
`

`
`6 accepts the reel 8,

`
`
`for example, processing of warehousing of
`

`
`The data

`
`Next, an electronic component mounting method executed by

`
`
`
`In the electronic component mounting

`
`method of
`
`an electronic component is registered in awhereabouts information
`
`

`
`First,
`
`
`the details of check-in processing executed by the
`
`check-in processing part 12 in the case of warehousing of an
`
`
`
`electronic component
`
`in the component keeping
`
`area 6© will be
`
`
`described with reference to Fig. 4.
`
`An electronic component
`
`targeted
`
`for the check-in processing includes both of the case
`
`
`
`
`of accepting
`
`a new unused electronic component in the component
`
`keeping
`
`component
`
`area 6 and the case of being returned as the remaining
`
`
`after use is started in the component mounting line la.
`
`
`
`
`As shown in Fig. 4,
`
`a
`
`component
`
`
`
`ID of an electronic component
`
`
`
`
`carried in the component keeping
`
`area 6 is read by the bar code
`
`reader 11
`
`(STI
`
`).
`
`The read result is transmitted to the member
`
`management part 4throughawireless LAN, andthe check-inprocessing
`
`
`
`part 12 determines whether or not the electronic component is an
`
`20
`
`
`
`
`unregistered component by referring to the material management
`
`
`
`information storage part 17 of the member management part 4 (ST2).
`
`In the case of determining that the electronic component is the
`
`
`
`new
`
`unregistered component in step ST2,
`
`the electronic component
`
`is newly registered (ST3). That is, using the read component
`
`ID
`
`as a
`
`key,
`
`a serial No,
`
`the component
`
`
`
`name 32, the number of inputs
`
`
`
`
`
`indicating the number of components per reel and the MSD flag 35
`
`automatically read from a host system and are written into
`
`
`are
`
`the material management
`
`table 30. Accordingly,
`
`the remaining
`
`
`number 33 shown in the material management table 30 of Fig.
`
`3 is
`
`updated and the MSD flag 351s displayed andalso when the electronic
`
`
`component is the MSD,
`
`
`according to an
` MSD level stored by the moisture management level storage part
`
`the exposure limit time 36
`
