Abstract

<P>PROBLEM TO BE SOLVED: To shorten a production time without requiring the reading of a circuit identification code attached to each divided substrate, and to enable an original substrate configuration to be determined even after the substrate is divided into circuit units. <P>SOLUTION: When the production history of circuits on separate split substrates 11 to 14 obtained by dividing a gang printed substrate 10 is managed; a substrate identification code 20 is attached to the gang printed substrate, and a circuit identification code 22 containing the substrate identification code in its part is attached to the separate split substrate. When components are mounted, the separate circuit identification code is not read in, but only the substrate identification code is read in, and the substrate identification code, components, and mounting places are left as a history. History information when mounting components can be retrieved from the circuit identification code even after the gang printed substrate is divided into the respective separate split substrates. <P>COPYRIGHT: (C)2007,JPO&amp;INPIT

Description

本発明は、多面取り基板の生産履歴管理方法及び多面取り基板に係り、特に、電子部品実装装置に用いるのに好適な、多面取り基板を使った生産時に、個々の割基板上の回路単位の生産履歴を残すための多面取り基板の生産履歴管理方法、及び、これに用いるのに好適な多面取り基板に関する。   The present invention relates to a method for managing production history of a multi-sided board and a multi-sided board, and particularly suitable for use in an electronic component mounting apparatus, in the production using a multi-sided board, the circuit unit on each split board. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a production history management method for a multi-sided substrate for leaving a production history, and a multi-sided substrate suitable for use in this method.

部品供給装置から供給される電子部品を吸着ノズルで吸着して、搬送されてくる基板に搭載する電子部品実装装置が知られている。   2. Description of the Related Art There is known an electronic component mounting apparatus in which an electronic component supplied from a component supply device is sucked by a suction nozzle and mounted on a substrate that is conveyed.

最近では、実装基板は、基板の小型化により、大きな一枚の基板に複数回路を設けた多面取り基板となっており、この多面取り基板では、部品実装後、基板を分割して個々の基板（割基板）としている（特許文献１、２参照）。   Recently, due to the downsizing of the board, the mounting board has become a multi-sided board in which multiple circuits are provided on a large board. In this multi-sided board, after mounting components, the board is divided into individual boards. (Refer to Patent Documents 1 and 2).

このような多面取り基板の生産で、各割基板上の回路単位の生産履歴（どの部品を何処の回路の何処に搭載したか）を残すためには、それぞれの回路に識別コードを付け、これを生産前に回路毎に読み取り、部品搭載時に、読み取った識別コードと部品、搭載場所を履歴として残す必要があった（特許文献３参照）。   In order to keep the production history of each circuit on each split board (which part is mounted on which circuit where) in such multi-chip board production, an identification code is attached to each circuit. Must be read for each circuit before production, and at the time of component mounting, the read identification code, component, and mounting location must be left as a history (see Patent Document 3).

しかしながら従来の方法では、割基板毎に付いた識別コードを全て読み取る必要があるため、割基板数（回路数）が多い場合には、読み取りにかかる時間が増えてしまい、結果として生産時間が増えてしまうという問題点を有していた。   However, in the conventional method, since it is necessary to read all the identification codes attached to each divided board, when the number of divided boards (number of circuits) is large, the time required for reading increases, resulting in an increase in production time. It had the problem that it ended up.

本発明は、前記従来の問題点を解消するべくなされたもので、識別コードの読み取り時間を節約すると共に、回路単位に分離した状態でも、元の基板構成が判断できるようにすることを第１の課題とする。   The present invention has been made to solve the above-mentioned conventional problems, and it is a first object of the present invention to save the reading time of the identification code and to determine the original substrate configuration even in a state where it is separated into circuit units. It is an issue.

本発明は、又、前記の生産履歴管理に適した多面取り基板を提供することを第２の課題とする。   It is a second object of the present invention to provide a multi-sided substrate suitable for the production history management.

本発明は、多面取り基板を分割して得られる個々の割基板上の回路の生産履歴管理に際して、前記多面取り基板の割基板以外の部分に基板識別コードを付すと共に、個々の割基板に該基板識別コードを一部に含む回路識別コードを付し、部品搭載時には、個々の回路識別コードを読み取ることなく、基板識別コードのみを読み取って、該基板識別コードと回路番号、搭載位置、部品シリアル番号、基板組込機のシリアル番号又は出荷先を履歴として残し、個々の割基板に分離した後でも、前記回路識別コードに含まれる基板識別コードから、部品搭載時の履歴情報の検索を可能として、前記第１の課題を解決したものである。 In the production history management of the circuit on each divided board obtained by dividing the multi-sided board, the present invention attaches a board identification code to a part other than the divided board of the multi-sided board and A circuit identification code including part of the board identification code is attached, and when mounting components, only the board identification code is read without reading the individual circuit identification codes, and the board identification code, circuit number, mounting position, and component serial number are read. No., the serial number of the board assembly machine, or the shipping destination is kept as a history, and even after separation into individual split boards, it is possible to search history information at the time of component mounting from the board identification code included in the circuit identification code This solves the first problem.

本発明は、又、部品搭載後、個々の割基板に分割される多面取り基板であって、前記割基板以外の部分に基板識別コードが付されると共に、個々の割基板に該基板識別コードを一部に含む回路識別コードが付されたことを特徴とする多面取り基板により、前記第２の課題を解決したものである。 The present invention is also a multi-sided board that is divided into individual divided boards after component mounting, and a board identification code is attached to a portion other than the divided board, and the board identification code is attached to each divided board. The second problem is solved by a multi-sided board characterized in that a circuit identification code including a part thereof is attached.

本発明によれば、多面取り基板の割基板以外の部分に基板識別コードを付すと共に、個々の割基板に該基板識別コードを一部に含む回路識別コードを付し、部品搭載時には、個々の回路識別コードを読み取ることなく、基板識別コードのみを読み取って、該基板識別コードと回路番号、搭載位置、部品シリアル番号、基板組込機のシリアル番号又は出荷先を履歴として残すようにしたので、部品搭載時に、多面取り基板の基板識別コードを読み取るのみで、個々の割基板上の回路の部品搭載履歴の把握が可能となり、生産時間を短縮できる。又、回路識別コードが基板識別コードを一部に含むようにしたので、個々の割基板に分離した後でも、回路識別コードに含まれる基板識別コードから元の基板構成の把握が可能となり、部品搭載時の履歴情報の検索が可能となる。 According to the present invention, the subjecting the substrate identification code in a portion other than the divided board of gang substrate, and with a circuit identification code comprising a part of the substrate identification code to each divided board, at the time of component mounting, the individual without reading the circuit identification code, reads only the substrate identification code, the substrate identification code and circuit number, mounting position, part serial number, since the residual Suyo serial number or shipping destination substrate set driving tool as history At the time of component mounting, it is possible to grasp the component mounting history of the circuit on each split board only by reading the board identification code of the multi-sided board, and the production time can be shortened. In addition, since the circuit identification code partially includes the board identification code , the original board configuration can be grasped from the board identification code included in the circuit identification code even after separation into individual split boards. The history information at the time of mounting can be searched.

以下図面を参照して、本発明の実施形態を詳細に説明する。   Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

本実施形態の生産履歴管理に用いる多面取り基板の構成例を図１に示す。本実施形態の多面取り基板１０は、部品実装後に例えば４枚に分割される割基板１１〜１４がマトリックス状に配置されたマトリックス基板であり、その割基板以外の部分に基板識別コード（ＩＤ）２０が付されると共に、各割基板１１〜１４に回路識別コード（ＩＤ）２２が付されている。   An example of the configuration of a multi-sided board used for production history management of this embodiment is shown in FIG. The multi-sided substrate 10 of this embodiment is a matrix substrate in which, for example, divided substrates 11 to 14 divided into four pieces after component mounting are arranged in a matrix, and a substrate identification code (ID) is provided on a portion other than the divided substrate. 20 and a circuit identification code (ID) 22 are attached to each of the divided boards 11 to 14.

前記基板識別コード２０は、他の多面取り基板１０と重複しないユニークなものとされ、前記回路識別コード２２は、該基板識別コード２０を一部に含むものとされる。   The board identification code 20 is unique so as not to overlap with the other multi-sided board 10, and the circuit identification code 22 includes the board identification code 20 in part.

例えば、基板識別コード２０が［０００１０］とすると、各割基板１１〜１４の回路識別コード２２は、それぞれ［０００１０−００１］［０００１０−００２］［０００１０−００３］［０００１０−００４］とすることができる。   For example, if the board identification code 20 is [00010], the circuit identification codes 22 of the divided boards 11 to 14 are [00010-001] [00010-002] [00010-003] [00010-004], respectively. Can do.

以下、作用を説明する。   The operation will be described below.

まず、部品搭載時には、それぞれの回路識別コード２２の読み取りは実行せず、基板識別コード２０のみを読み取り、後出図３に例示する如く、基板識別コード（基板ＩＤ）２０と搭載場所、部品シリアル番号、出荷先を履歴として残す。ここで、前記搭載場所は、電子部品実装装置で管理している回路位置に対応する回路番号と搭載位置を含む。 First, at the time of component mounting, the reading of the respective circuit identification code 22 does not execute and read only the substrate identification code 20, as illustrated in the rear above-mentioned FIG. 3, the substrate identification code (substrate ID) 20 and tower mounting location, parts Keep serial number and shipping destination as history. Here, the mounting Place includes circuit number and the mounting position corresponding to the circuit positions managed by the electronic component mounting apparatus.

具体的には、図２に示す如く、部品実装のステップ１００において、ステップ１０２で基板搬入後、ステップ１０４で基板ＩＤを読み取って、図３に示す如くメモリの例えばＡ欄に記憶する。   Specifically, as shown in FIG. 2, in step 100 of component mounting, after board loading in step 102, the board ID is read in step 104 and stored in, for example, column A of the memory as shown in FIG.

次いでステップ１０６で、部品吸着で吸着した部品のシリアル番号を、メモリの例えばＢ欄に履歴として残す。   Next, at step 106, the serial number of the component sucked by the component pick-up is left as a history in, for example, column B of the memory.

次いでステップ１０８で、部品搭載で搭載回路に対応する回路番号、搭載位置に対応する搭載位置ＩＤ、部品シリアル番号、出荷先を図３に示す如く履歴として残す。 Then in step 108, the circuit number corresponding to the mounting circuit component mounting, mounting location ID corresponding to the mounting position, the component serial number, leaving the shipping destination as history as shown in FIG 3.

全ての搭載点に部品を搭載したとステップ１１０で判断されるまで、上記ステップ１０６及び１０８を繰り返す。ステップ１１０で全ての搭載点に搭載したと判断されたときに、ステップ１１２で基板を搬出する。   Steps 106 and 108 are repeated until it is determined in step 110 that components have been mounted on all mounting points. When it is determined in step 110 that all the mounting points have been mounted, the substrate is unloaded in step 112.

部品実装後、ステップ１２０に進み、基板１０を回路単位に分割し、基板組込機のシリアル番号又は出荷先を履歴に残す。 After mounting the components, the process proceeds to step 120, where the board 10 is divided into circuit units, and the serial number of the board built-in machine or the shipping destination is left in the history.

このようにすることで、回路単位に分離した状態でも、回路識別コード２２から該回路識別コード２２に含まれる基板識別コード２０を知って、図３に例示したような部品搭載時の履歴情報の検索が可能となる。具体的には、図４に示す如く、例えば客先で不具合が発生し（ステップ２００）、不具合解析後、部品不良が判明（ステップ２０２）した後で、ステップ２０４に進み、図３に示した履歴情報を用いて、該当回路のＩＤから、該回路ＩＤに含まれる基板ＩＤの履歴情報を検索して不良部品の部品シリアル番号を特定し、該特定した部品シリアル番号から、ステップ２０６で、図３に例示した履歴情報を検索して該不良部品を搭載した割基板を含んでいた基板の基板ＩＤを特定し、ステップ２０８で、該基板ＩＤと回路ＩＤから前記不良部品を搭載した割基板を組み込んだ機械の出荷先（基板組込機のシリアル番号）を特定することができる。このようにして、部品不良発生後、その不良部品を使用した割基板を組み込んだ機械の出荷先をトレースすることができる。 In this way, even in a state where the circuit is separated in units of circuits, the circuit identification code 22 knows the board identification code 20 included in the circuit identification code 22, and the history information at the time of component mounting as illustrated in FIG. Search is possible. Specifically, as shown in FIG. 4, for example, a defect occurs at the customer (step 200), and after analyzing the defect, a component defect is determined (step 202), and then the process proceeds to step 204, as shown in FIG. 3. Using the history information, the history information of the board ID included in the circuit ID is searched from the ID of the corresponding circuit to identify the component serial number of the defective component. From the identified component serial number , 3 is specified to identify the board ID of the board that includes the split board on which the defective part is mounted , and in step 208, the split board on which the defective part is mounted is determined from the board ID and circuit ID. It is possible to specify the shipping destination of the incorporated machine (serial number of the board built-in machine ). In this way, after the component failure, it is possible to trace the shipping destination of the machine incorporating the divided board using the defective parts.

なお、前記実施形態においては、多面取り基板が４回路のマトリックス基板とされていたが、本発明の適用対象はこれに限定されず、４回路以外の割基板にも同様に適用できる。   In the above-described embodiment, the multi-sided substrate is a four-circuit matrix substrate. However, the application target of the present invention is not limited to this, and can be similarly applied to a split substrate other than four circuits.
