Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual stencil step design method is used, then design flexibility and operator control are maintained, but design time increases significantly and error probability increases
Solution Approach 1:
The system performs automatic stencil step design by having the computer automatically identify apertures requiring steps, calculate step parameters, and generate design files based on preset rules, eliminating the need for manual intervention and significantly reducing design time while maintaining accuracy
Solution Approach 2:
The patent replaces the manual mechanical design process with an automated computer-based system that uses algorithms to identify apertures, calculate step ranges, and generate design files, substituting human operators with automated software to reduce time consumption and errors
2Ease of manufacture
If manual stencil step design is performed, then complex modifications can be handled, but operator skill requirements increase and labor costs rise
Solution Approach 1:
The automated system performs all stencil step design operations independently, including aperture identification, step parameter calculation, and design file generation, making the complex process easy to operate through simple software execution without requiring skilled operators
Solution Approach 2:
The software system integrates multiple functions including Gerber file import, aperture data extraction, step design calculation, and design file output into a single automated platform that can handle various stencil design scenarios, reducing the need for multiple specialized tools or highly skilled operators

AI summary
A stencil step design method and system, a computer readable storage medium and a device. The method comprises: acquiring data of stencil apertures for electronic components in a circuit board, and identifying the stencil apertures for electronic components one by one to determine whether the stencil apertures need to be stepped; and if yes, performing step design for the stencil apertures that need to be stepped according to preset step rules corresponding to the stencil apertures for electronic components one by one so as to generate a stencil step design file with the step design, and outputting the stencil step design file. According to the present disclosure, 90% or more steps can be automatically designed and the stencil step design is in conformity with processing requirements. A manual intervention process is omitted, and the design can be accomplished by several simple steps.
