Engineering Contradiction Analysis
1Manufacturing precision
If expert experience and trial-and-error methods are used to determine soldering parameters, then soldering quality can be improved, but the time and cost for parameter testing increases significantly
Solution Approach 1:
The system pre-establishes a database of material characteristics and component properties before the actual soldering process. By preparing reference data in advance and using machine learning models to pre-calculate optimal parameters, the system eliminates the need for time-consuming trial-and-error testing during production, directly resolving the contradiction between quality and testing time
Solution Approach 2:
The patent replaces the manual expert-based trial-and-error method with an automated machine learning system. The machine learning model automatically analyzes material and component characteristics to determine optimal soldering parameters, substituting human expert judgment and physical testing with computational algorithms, thereby dramatically reducing testing time while maintaining or improving soldering quality
2Measurement precision
If multiple test accumulations are performed to determine soldering parameters, then parameter accuracy can be improved, but production efficiency decreases
Solution Approach 1:
The system creates a virtual model (copy) of the soldering process using machine learning algorithms that simulate the effects of different parameters on soldering quality. Instead of performing multiple physical test accumulations, the system uses computational models to predict optimal parameters, maintaining measurement precision while eliminating the need for repeated physical testing that reduces productivity
Solution Approach 2:
The machine learning system continuously learns from process data and automatically refines its parameter recommendations without requiring external intervention or repeated testing. The system serves itself by using accumulated production data to improve its own accuracy over time, eliminating the need for separate test accumulation phases and thereby maintaining high production efficiency
3Ease of manufacture
If conventional trial-and-error methods are used, then soldering parameters can be determined, but automation and flexible production are limited
Solution Approach 1:
The patent replaces manual expert-based parameter determination with an automated machine learning system that can be integrated into production line control. The system automatically inputs material and component characteristics and outputs optimal soldering parameters, enabling full automation of the parameter determination process and removing the limitation on production line automation inherent in conventional methods
Solution Approach 2:
The machine learning system is designed to handle diverse material types and component characteristics through a unified framework. By using universal algorithms that can process various input characteristics and adapt to different soldering scenarios, the system enables flexible production across multiple product types while maintaining automation, something that conventional expert-based methods struggle to achieve

AI summary
A soldering process method includes steps of: establishing a material component database; establishing a working parameter database; analyzing material and component characteristics required for a new soldering process; comparing the characteristics with information in the material component database; selecting operating parameters corresponding to the material and component characteristics similar to those required for the new soldering process; performing the soldering process using the operating parameters corresponding to the material and component characteristics similar to those required for the new soldering process; measuring and recording the soldering process execution information and the final product information; determining whether the final product of the solder process meets the quality control requirements; using the machine learning method to fit the soldering process execution information and the final product information of the solder process to get the operating parameters for the next soldering process when the final product does not meet the quality control requirements.
