Engineering Contradiction Analysis
1Measurement precision
If traditional microscopic examination techniques are used to detect degradation modes, then measurement precision is improved, but device complexity and loss of time increase due to destructive preparation and significant human resources required
Solution Approach 1:
The patent replaces mechanical/optical examination systems with an electromagnetic field-based detection system. The RF microscope uses electromagnetic signals to probe and detect degradation modes in electronic components, eliminating the need for mechanical disassembly, optical microscopy setup, and extensive human analysis. The system automatically detects degradation through electromagnetic signal analysis, significantly reducing device complexity and preparation time while maintaining high measurement precision.
2Measurement precision
If destructive methods are used to expose internal degradation modes, then measurement precision is improved, but reliability of the monitored system deteriorates due to component damage
Solution Approach 1:
The patent employs self-service by using the electronic component's own operational electromagnetic signals as the probe. The component operates normally during testing, and its self-generated electromagnetic emissions are analyzed to detect degradation modes. This eliminates the need for external destructive probing or disassembly, allowing detection of internal degradation while preserving component integrity and reliability.
3Measurement precision
If significant human resources are allocated for analysis, then measurement precision is improved, but productivity deteriorates due to time-consuming examination processes
Solution Approach 1:
The patent implements automated feedback-based analysis where the RF microscope system continuously monitors electromagnetic signals, automatically processes the data through analysis algorithms, and generates diagnostic results without requiring significant human intervention. The system provides real-time feedback on component health status, dramatically increasing productivity while maintaining high measurement precision through automated pattern recognition and degradation detection.
