Soldering Apparatus Camera Image Storage for Defect Investigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current soldering apparatuses struggle to confirm abnormalities in substrates after they have been shipped out, as they lack the ability to capture and store images associated with specific soldering operations, making it difficult for manufacturers to investigate customer-reported defects and improve identification criteria.
Innovation Solution
A soldering apparatus equipped with a camera that captures and stores image data during soldering operations, associating it with the relevant substrate, location, and operation details, allowing for later analysis and confirmation of abnormalities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If image data is captured and stored during soldering operations, then the ability to confirm abnormalities post-shipping is improved, but the device complexity increases
Solution Approach 1:
The system captures and stores image data during the soldering operation before the substrate is shipped. This preliminary action ensures that visual records of the soldering quality are preserved, enabling later verification of abnormalities without requiring the substrate to be physically present or re-soldered.
Solution Approach 2:
Instead of retaining the physical substrate for inspection, the system creates and stores digital image copies of the soldering areas. These image copies serve as surrogates that can be reviewed, analyzed, and compared at any time after shipping, eliminating the need for complex physical inspection infrastructure.
2Loss of time
If image data is stored in association with soldering operations, then the time to investigate defects is reduced, but the loss of information is increased due to potential data management challenges
Solution Approach 1:
The system establishes a feedback loop where image data captured during soldering is stored and made accessible for later review. When abnormalities are reported, the stored images provide immediate visual feedback that allows rapid verification and investigation, eliminating the time delay associated with waiting for substrate return or re-inspection.
Solution Approach 2:
By capturing and organizing image data with associated metadata (substrate identifiers, soldering parameters, timestamps) during the initial soldering operation, the system prepares the information structure in advance. This preliminary organization ensures that when defects are reported, the relevant images can be quickly retrieved and correlated with specific soldering conditions without information loss.
3Measurement precision
If image data is captured during soldering, then the precision of abnormality identification is improved, but the use of energy increases due to camera and storage operations
Solution Approach 1:
The system captures image data selectively during soldering operations rather than continuously monitoring all processes. By focusing imaging resources only on critical soldering moments and areas, the system achieves sufficient precision for abnormality identification while minimizing the energy consumption associated with camera operation and data storage.
Data Source
AI summary
A soldering apparatus and method involves capturing an image of a soldering operation, and storing image data in association with that particular soldering operation. A soldering tool that is used to perform the soldering operation has a position during the soldering operation, and the image data could also be stored in association with data for that particular position. The position data could be for an operation start point and/or an operation endpoint. Associating the image data in this way could help a manufacturer investigate soldering abnormalities that might be reported after a product is shipped to a customer.
