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.
