Production Quality Timeline Analysis for PCB Fault Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing management support apparatuses for production facilities cannot effectively analyze and determine measures for multiple types of faults or errors occurring in printed circuit board production, as they fail to distinguish simultaneous or sequential occurrences, concentration of errors, and state transitions.
Innovation Solution
A quality improvement support apparatus that displays production condition information in a time series, associating quality information with production members or components, allowing for chronological analysis of unit products to identify temporal tendencies and separate causes of abnormalities, including event information to contextualize faults and errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If conventional management support apparatuses display faults and errors in various manners, then the information can be visualized, but it is not possible to know whether faults occurred at the same time or on the same circuit board, or to identify temporal tendencies and state transitions
Solution Approach 1:
The patent segments the display into separate time series for each production member or component, with quality information arranged chronologically for each segment. This segmentation allows clear identification of temporal tendencies and state transitions while maintaining manageable complexity through organized separation of data streams.
Solution Approach 2:
The patent adds a temporal dimension to the display by arranging quality information in time series order for each production member. This dimensional transformation enables the identification of temporal tendencies (sudden occurrence, continuous occurrence) and state transitions that cannot be detected in conventional static displays.
2Quantity of substance
If multiple types of faults and errors are displayed without temporal context, then all error information is visible, but it becomes impossible to analyze causes efficiently or determine whether errors are concentrated in specific time or circuit boards
Solution Approach 1:
The patent performs preliminary organization of error information by arranging quality information in chronological order for each production member before analysis. This preliminary temporal structuring enables rapid identification of patterns and causes without requiring complex post-processing analysis, thereby improving cause analysis speed while maintaining complete error information visibility.
3Device complexity
If quality information is not arranged chronologically for each unit product, then the display structure is simpler, but it is impossible to recognize chronological fluctuations or separate causes affecting temporal tendencies of abnormalities
Solution Approach 1:
The patent segments the display structure into distinct time series for each production member or component, with quality information arranged chronologically within each segment. This segmentation achieves precise temporal fluctuation detection while maintaining display simplicity through organized separation, resolving the contradiction between structure simplicity and detection precision.

AI summary
A quality improvement support apparatus that supports improvement in quality of products produced by a production facility includes a display unit that displays production condition information in which quality information regarding the quality occurring or detected in a production step performed by the production facility is arranged in time series in association with a production member or a component included in the production facility, wherein, in the production condition information, the quality information of each product or a plurality of the products occurring or detected in relation to the production member or the component included in the production facility is arranged in an order in which the products are produced.
