Abstract: A stencil-avoidance design method, a stencil-avoidance design device, an electronic device, and a non-transitory storage medium are provided. The method includes: obtaining a plurality of first regions and a plurality of first stencil aperture regions; determining whether a shortest distance between a selected first region of the plurality of first regions and a selected first stencil aperture region of the plurality of first stencil aperture regions is within a preset threshold range; further obtaining a second region and a second stencil aperture region if the shortest distance is within the preset threshold range, and then obtaining a third region; performing a collision step if a collision test is required, and obtaining a final stencil aperture region. The above method can improve the efficiency, accuracy, coverage, and comprehensiveness of the stencil avoidance design.

Abstract: 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.
