Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention provides a comparatively large management device for the production of electronic parts having a built-in storage device, instead of centrally managing information relating to individual electronic parts. The present invention relates to a method of performing production control and quality control of electronic components by utilizing a part of a storage device incorporated in the electronic components themselves and utilizing a relatively small-scale facility having versatility.

[0002]

2. Description of the Related Art As a conventional method for controlling production and quality of electronic parts, for example, a method shown in FIG. 3 has been used. In this method, each electronic component subject to production control and quality control is given an ID (identification symbol) by, for example, a bar code or the like, and is externally controlled for production control and quality control. Set up. Production process,
A bar code reader is installed in each inspection process to read the ID of the electronic component flowing through the process, and the production and inspection information is sent to and stored in the external control device in association with this ID. As a result, all the information about each electronic component relating to production and inspection is stored in the external storage device linked with the control device. The external storage device, the bar code reader, each production process, and the inspection process are collectively controlled by the control device, and production control and quality control are performed based on the information in the external storage device. In addition, in FIG.
Reference numeral 1 is an electronic component, 2 is a storage device built in the electronic component, 3 is a bar code which is an identification symbol given to each electronic component to identify each electronic component, 4 is a bar code reader for reading a bar code, and 5 is electronic. A conveyor device such as a belt conveyor that sequentially changes the position of the electronic component to be produced in the component production process in the order of steps, 6 is a production process, 7 is an inspection process, 8 is a control device for production (management) provided outside, and 9 Is an external storage device for the control device.

[0003]

However, in the conventional method for production control and quality control of electronic parts as described above, only the ID (identification symbol or bar code) is used as information to be given to each electronic part. Yes, since all the information on production and inspection of each electronic component is stored in the external storage device, it is necessary to increase the capacity of the external storage device as the production quantity increases. Management costs a huge amount of money. Further, the larger the amount of information, the longer the processing takes, and thus a sophisticated control device is required. Since information is also exchanged indirectly through a barcode attached to an electronic component, there is a problem that information may be mistakenly referred to.

In order to solve the above-mentioned problems of the conventional method of controlling the production and quality of electronic components, the present invention utilizes a part of the storage device incorporated in the electronic components for the purpose of use. Then, in the conventional method, the information on the production control and the quality control, which are all stored in the external storage device of the control device, and the information on the related processes to be performed in the subsequent process are stored in each electronic component itself. It is an object of the present invention to establish a method that is far easier and less expensive than the conventional method for controlling the production and quality of electronic parts by making distributed storage in existing storage devices.

[0005]

In order to solve the above-mentioned problems, according to the present invention, in the production process and the inspection process of an electronic part having a built-in storage device, the electronic part itself is provided as a part of the built-in storage device. Means for reading and writing production information, inspection information, and instruction information for subsequent steps, means for managing information relating to production steps and inspection steps using this storage device as a medium, and inter-process steps by the instruction information for the subsequent steps. Means for transmitting information and setting optimum process conditions for each product. As the production information, at least one or more of a production lot, a worker name, a production date, a production time, a temperature and humidity at the time of production, an equipment name, a component name, a component lot, and a correction history are inspected. At least one or more of measurement data and inspection result is provided as information, and at least one or more of a work instruction, a process sequence instruction, an equipment program name, and an inspection standard is provided as instruction information for a post-process.

FIG. 1 is a diagram showing an embodiment of the present invention. In the figure, 1
Reference numeral 1 is an electronic component that is a production or quality control target, 12 is a storage device built in the electronic component, 13 is a production information communication device for causing the storage device 12 to read production information in a production process 16, and 14 is a storage device. An inspection information communication device for reading the inspection result and inspection data in the inspection process 17 into the storage device 12, and 15 is a conveyor device such as a belt conveyor that sequentially changes the position of the electronic component to be produced in the process of producing the electronic component in the production process of the electronic component. Is. By doing so, the storage device 12 built in the electronic component 11 stores in the storage device 12 the production environment information of the electronic component 11 itself, which is a production or quality control target, such as a worker name, a production facility number, a facility program, a production date and time. Information such as production information such as component information and lot information and inspection results, inspection data, inspection information such as inspection standards, instructions for modifying the same, instructions for changing process settings, instructions for branching lines, etc. for subsequent processes can be read and written. It Note that a non-volatile memory such as an EPROM is used as the storage device 12 so that the stored data can be reliably held even during different steps. However, when the electronic component 11 has its own power source such as a battery or a backup capacitor, it is possible to receive power from this power source and hold the stored data.

FIG. 2 is a diagram for explaining the flow of information. First, when processing or assembly is completed in the production process 16, the production information 18 and the instruction information 19 for the subsequent process are written in the storage device 12 of the electronic component 11 as described above. In the next production process 16a, first, the instruction information 19 is read, and the process is set according to the instruction. After that, when the processing and assembly are finished, the production information 18a and the instruction information 19a for the subsequent process are written. In the next inspection step 17, first, the instruction information 19
A is read, and the process is set (changed) according to the instruction. After that, when the inspection is completed, the inspection result information 20 and the instruction information 19b for the subsequent process are written.
