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.

Abstract: A PCB stencil manufacturing method and system. The method comprises: inputting PCB stencil design information in a preset input format, the PCB stencil design information comprises solder pad element information; and converting the PCB stencil design information into corresponding system core data information, the system core data information comprises solder pad element packaging information, and the solder pad element packaging information comprises a solder pad element packaging pattern and solder pad element coordinates; and querying a stencil opening database according to the solder pad element packaging pattern, records in the stencil opening database comprise the following attributes: a solder pad element packaging pattern and a stencil opening pattern; and placing a stencil opening pattern corresponding to a matching solder pad element packaging pattern to an opening layer according to the solder pad element coordinates.
