The operation information is displayed based on the storage contents of the shared files 2 and 5 of the component mounting apparatus 1 or the external computer 4.

These information management systems can control a production device such as the electronic component mounting device 1 installed at a remote place. That is, as shown in FIG. 2, the device control computers 1a, 1b, 1c, 1d, and 1e of the respective production devices installed in the remote factories are connected to each terminal via the router 9 via the LAN communication line 3. It is connected to personal computers 4a, 4b, 4c, 4d, 4e and a host computer (server) 10. in this case,
Computer 1a, 1b, 1 for device control of each production device
External storage devices c, 1d, and 1e (not shown) and the server 10
The shared storage device (not shown) has a shared file structure by providing shared files 2 and 5, respectively. Although not shown, the personal computer 4
Each of a, 4b, 4c, 4d, and 4e has a dedicated display.

Accordingly, the external storage devices of the device control computers 1a, 1b, 1c, 1d, and 1e of the respective production devices and the external storage device of the server 10 share files 2, 5,
Each personal computer 4
a, 4b, 4c, 4d, and 4e, as long as the shared files of the server 10 are accessed, desired operation information and production Information and alarm / stop information can be obtained, and operating conditions and the like can be changed. As a result, each personal computer 4a, 4b,
The access loads from 4c, 4d, and 4e are directly transmitted to the device control computers 1a, 1b, 1c, 1d,
1e, the stability of the computer 1a, 1b, 1c1d, 1e for controlling the production apparatus can be increased.

As shown in FIG. 3, the flip chip bonder, which is a production apparatus, sequentially transports substrates 13a, 13b, 13c, 13d,... The substrates 13a, 13b, 13c, 1
An adhesive is applied to predetermined portions of 3d. On the other hand, the wafer 17 stored in the wafer cassette 16 is diced into chips and is placed on the wafer table 18.

The substrates 13a, 13b, 13c, 13d,... To which the adhesive is applied at predetermined locations by the dispenser 15,
When transported to the position of the bonding head 19, the substrate 1
A predetermined chip 20 is temporarily attached by the pickup head 21 to each location where the adhesives 3a, 13b, 13c, 13d,... Are applied. This temporarily attached chip 2
The bonding head 19 descends from above and presses to mount the chip 20.

Therefore, in the case of production by a flip chip bonder, operation information such as product data, pressurization conditions, substrate feed pitch, position recognition result, wafer size, processing time, chip to be bonded, production information, alarm /
Stop information is always subject to control and management.

In addition to the information unique to the production apparatus, the operation information usually includes an operation time, an operation start time, an operation end time, an operation rate, a stop reason, etc. which are common to various production apparatuses. .

The production information covers the number of non-defective products, the yield, the number of defective products for each reason, in addition to the production time and the number of products, and the alarm / stop information includes information for each alarm in addition to the equipment stop time. The stop time, the number of alarm occurrences, the stop time for each reason, the number of stops, the trouble processing time, the number of trouble stops, and the like are covered.

The operation information, the production information, and the alarm / stop information need to be updated when the respective target information exceeds the allowable range of the predetermined value or when the set value is changed.

Accordingly, the operation information, the production information and the alarm / stop information are stored in the device control computer 1 of each production device each time the target information is updated.
a, 1b, 1c, 1d, 1e external storage device and server 1
0 shared files 2 and 5 are updated.

As a result, the personal computers 4a,
The users 4b, 4c, 4d, and 4e can always check the update status of the shared file 5 on the server 10, and when the update process occurs, the latest operation information displays the server 10 on the respective computer displays. Is done. Further, when there is urgency, a message display can be simultaneously displayed.

Each of the personal computers 4a, 4a
b, 4c, 4d, and 4e, the operation information, production information, alarm / stop information, and the like sent from the device control computers 1a, 1b, 1c, 1d, and 1e of the respective production devices are read in a day, week, month, and the like. , And can be collected and analyzed as production performance management information, quality management information, maintenance management information, process analysis information, and the like.

The production management based on them is, for example, as follows.

Progress management: Production status display by lot Production performance management: Performance management for production plan Shinaga management: Defect item analysis, yield management Production instruction: Production number instruction by lot, instruction of setup contents Production simulation: By process Grasping of production time By managing these indices, predetermined stable production can be continued.

According to the configuration described above, the LAN communication (TCP / IP protocol), which is currently becoming the industry standard, is directly adapted to the production apparatus (such as the electronic component mounting apparatus 1), so that the operation information / production information can be obtained.・ Alarm / stop information can be directly retrieved. Therefore, information can be taken out in real time, and based on this information, the computer 1a, 1b, 1c, 1d, 1c, 1c, 1d for each device can be quickly controlled via the LAN communication line.
1e can be remotely controlled.

Further, since it is not necessary to newly install additional equipment for information collection, only maintenance of the LAN is required, and the load of system management is small. Further, the host computer (server 10) uses the personal computer 4 to share information with a shared file-based sharing service.
a, 4b, 4c, 4d, and 4e can be used, and there is no need to provide a dedicated host computer 10, and processing can be performed at a low cost.

In the above embodiment, the computer 1a, 1b, 1c, 1d for controlling the production apparatus is stored in the external storage of the host computer (server) 10.
Although the shared file 5 with the computer 1e is provided, the computer 1a, 1b, 1c, 1
As long as the access load on d and 1e is reduced, for example, a shared file may be provided for at least one appropriately selected personal computer (for example, a shared file may be provided in the personal computer 4a, and Personal computer 4
b, 4c, and 4d may access the shared file of 4a from the personal computer.)

Although the present invention has exemplified the electronic component mounting apparatus as the production apparatus, the production apparatus is not limited to this, and may be applied to any apparatus controlled by a computer.

Further, since the present invention can be adapted to each other at a remote location as described above, it goes without saying that, for example, equipment in a remote factory can be managed and maintained from a central head office.
