Solder Printer Quality Control via Automated Remedial Measures
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current solder printing technologies face challenges in maintaining print quality, leading to deterioration and potential failures due to inadequate remedial measures, which are not effectively determined or executed in real-time.
Innovation Solution
A printing operation assisting device that automatically determines and issues remedial measures based on print-result information from an inspecting machine, allowing for stepwise adjustments to prevent print quality deterioration and potential failures by determining appropriate actions such as cleaning, adjusting solder cream, or changing printing conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If remedial measures are determined based on print result inspection, then print quality can be improved, but the system complexity increases due to integration of inspecting machine and measure determination functions
Solution Approach 1:
The patent combines the inspecting machine, measure determining portion, and measure issuing portion into an integrated system. The measure determining portion receives print result information from the inspecting machine and automatically determines remedial measures, merging inspection and remediation functions into a unified system that improves print quality while managing complexity through functional integration.
Solution Approach 2:
The system implements a feedback loop where the inspecting machine continuously monitors print results, and the measure determining portion uses this feedback information to automatically determine and issue appropriate remedial measures. This closed-loop feedback mechanism enables real-time quality improvement without requiring complex manual intervention systems.
2Reliability
If stepwise remedial measures are implemented, then print quality deterioration is prevented more effectively, but the response time and operational complexity increase
Solution Approach 1:
The patent implements stepwise remedial measures where the measure determining portion determines multiple remedial measures in advance based on different print quality deterioration scenarios. When deterioration is detected, the system can immediately execute the pre-determined appropriate measure, preventing further quality deterioration without requiring complex real-time analysis for each intervention.
Solution Approach 2:
The remedial measure determination process is segmented into discrete, manageable steps. The measure determining portion divides the remediation process into specific remedial measures (e.g., cleaning the screen, adjusting printing parameters) that can be executed independently and sequentially, making the complex remediation process more manageable and faster to implement.
3Productivity
If automatic remedial measure determination is implemented, then manual intervention is reduced, but the device complexity and initial setup requirements increase
Solution Approach 1:
The patent implements automatic remedial measure determination where the measure determining portion autonomously analyzes print result information and determines appropriate remedial measures without requiring continuous manual intervention. The system serves itself by automatically detecting quality issues and selecting remediation actions, significantly improving operational efficiency while the complexity is encapsulated within the automated determination module.

AI summary
A printing operation assisting device for assisting a printing operation performed by a solder printer configured to print a solder cream on a substrate surface, including: a measure determining portion configured to determine a remedial measure against a deterioration of a print quality specified on the basis of print-result information obtained from an inspecting machine configured to inspect a print result by the printer, in accordance with a kind of the print-quality deterioration; and a measure issuing portion configured to issue a command relating to the remedial measure determined by the measure determining portion to at least one of the printer and its operator, wherein the measure determining portion is configured to determine a remedial measure against a certain print-quality deterioration and to redetermine another remedial measure different from the previously determined remedial measure where the deteriorated print quality is not improved by execution of the previously determined measure.
