JPH04363030A - Production-lot organization system of electronic-circuit package - Google Patents

Abstract

PURPOSE:To organize a production lot according to a situation of whether components are provided sufficiently or not, to be capable of shifting the production lot to a production line immediately after the components have been provided sufficiently even in the case of an insufficiently provided order and to reduce an unfinished situation at a lot acceptance port. CONSTITUTION:The title system is provided with lot organization means 102, 103 and a component-sufficiency confirmation and indication means 104. It is constited of the following: a function to control the sufficiency situation of components; and a function to organize a lot to be shifted to a production line.

Description

[Detailed description of the invention]

0001

[Industrial Application Field] The present invention relates to the production of electronic circuit packages, and in particular to electronic circuit packages for realizing an input lot organization system when producing electronic circuit packages using parts assembly machines, testing machines, etc. This relates to the production lot organization system.

0002

[Prior Art] Conventionally, this type of production lot organization system has organized input lots only for orders that can be input to the production line, for example, for which there are no missing parts or for which equipment such as parts assembly machines has been maintained. Therefore, even if an order that cannot be placed becomes possible, it has to wait until the next lot is formed, resulting in poor production efficiency.

0003

[Problems to be Solved by the Invention] In the above-mentioned conventional production lot organization system, only orders that can be input are considered, which delays the input of orders that can be input into the production line, and also causes delays in inputting orders that can be input into the production line. There was a problem with the increase in work in progress.

0004

[Means for Solving the Problems] In electronic circuit package production in which there are multiple process routes for high-mix, low-volume production, the present invention provides a process route and substrate type for each type of electronic circuit package that can be ordered to a production line without any shortages. a first lot organization means that organizes lots by grouping code, a second lot organization means that organizes lots by type of electronic circuit packages that are waiting to be placed; The system is equipped with a parts sufficiency confirmation instruction means that cancels the waiting state after confirming parts sufficiency and instructs line input, and organizes production input lots to reduce work in progress between processes and shorten process routes. be.

[0005]

[Operation] In the present invention, orders that can be introduced into the production line and orders waiting to be introduced are organized into lots separately, and the lot organization of the orders waiting to be introduced is performed for each order that can be introduced.

[0006]

[Embodiment] FIG. 1 is an explanatory diagram showing an embodiment of the present invention.
Shows the process route and parts sufficiency status of orders placed on the production line. Figure 2 is an explanatory diagram showing the production parts configuration.
Shows the component parts of the product produced for each order and the sufficiency status of each part. In FIG. 2, * marks indicate missing parts. FIG. 3 shows a flowchart of input lot organization, and in each step 101, 102, 103, 104, a predetermined process is executed.

At step 101 in FIG. 3, the state of parts sufficiency is determined, and if the parts sufficiency is OK, step 102
Then, the OK part is organized into lots. Here, this step 102 constitutes a lot organization means that organizes a lot in units of grouping codes in which process routes and board types are categorized for each type of electronic circuit package that can be ordered on a line without any shortages. Step 103 is a step for organizing a lot for NG items, and this step 103 constitutes a lot organization means for organizing each type of electronic circuit package waiting to be placed. Here, since the missing parts are filled for each component type, orders for out-of-stock parts and waiting for input are organized into lots for each electronic circuit package type. Step 104 is a step for determining whether parts sufficiency is OK or NG. This step 104 constitutes parts sufficiency confirmation instructing means for canceling the waiting state after confirming parts sufficiency in a lot that is out of stock and waiting for input, and instructing line input. There is. The system is configured to organize input lots for production in order to reduce in-process work between processes and shorten process routes.

FIG. 4 is an explanatory diagram showing an image of input lot organization. Next, a production line input lot organization system will be explained with reference to FIG. 1 using FIGS. 3 and 4. first,
Orders b, d, with fulfilled parts that can be input to the production line
Lot organization is performed for each grouping code using f and g. As shown in Figure 1, since the grouping codes of orders b and d are both B, lot b and d (LOT1
). In addition, as shown in FIG. 1, the order f,
Since the grouping codes of g are both C, they are treated as the same lot (LOT2) and put into the production line. Next, orders a, c, and e (see FIG. 1) that are out of stock are organized into lots. At that time, lot organization is performed taking into consideration how parts will be available. Here, since parts are delivered and filled for each product name, there is a high possibility that parts will be filled for each type of electronic circuit package. Therefore, out-of-stock orders are organized into lots for each type of electronic circuit package and are kept waiting to be put on the line. Orders a, c, and e in this example are organized into lots for each type of electronic circuit package (LOT3, LOT3,
OT4, LOT5).

[0009] Immediately after filling the missing parts (a), LOT3
, LOT4 to the line. Next, when the missing parts (e) are satisfied, LOT5 is introduced.

0010

[Effects of the Invention] As explained above, the production lot organization method for electronic circuit packages of the present invention makes it possible to organize orders that can be introduced into the production line and orders waiting to be introduced into separate lots, and to input the lot organization of orders that are waiting to be introduced. Since this is done for each order, it has the effect of shortening the time required to complete the process, improving the immediacy of input to the production line, and improving line operating efficiency.
