Problems solved by technology

[0004] The welding of the shielding frame needs to design the corresponding stencil opening on the PCB stencil design, and different opening designs will lead to different welding effects
[0005] At present, the solder pads of the shielding frame are printed with solder paste through the opening of the stencil. The opening method of the stencil opening of the shielding frame is to directly use the pads of the shielding frame in the PCB design data for opening. The stencil opening obtained by this method, During welding, there will be problems such as insufficient steel mesh stress, difficulty in removing tin, and hidden dangers of device collision.

Abstract

The invention discloses a shielding frame steel mesh opening method, device, electronic equipment and storage medium. The method includes: obtaining the first shielding frame steel mesh opening; The included corners of the openings bridge the included corners of the first shielding frame stencil openings to obtain the second shielding frame stencil openings; The preset length, the adaptive continuous opening length value and the minimum opening width value perform bridging processing on the stencil opening of the second shielding frame stencil opening to obtain a third shielding frame stencil opening. The shielding frame stencil opening method of the present invention can make the stress distribution of the finally generated stencil opening scheme reasonable, facilitate tin removal, and can effectively avoid the hidden danger of shielding frame and device collision, avoid human intervention, and reduce production costs. The error rate reduces the production cost of the enterprise and improves the competitiveness of the product.

Description

technical field [0001] The invention belongs to the technical field of printed circuit boards, and in particular relates to a method, device, electronic equipment and storage medium for opening a steel mesh of a shielding frame. Background technique [0002] The rapid development of the electronic manufacturing industry has made highly integrated and high-density electronic products more and more widely used, which has also caused many electromagnetic interference problems. In order to solve such problems, it is necessary to use shielding covers in hardware design to prevent external radiation and interfered with by radiation. A shield is a tool used to shield electronic signals. The function is to shield the influence of external electromagnetic waves on the internal circuit and the external radiation of electromagnetic waves generated inside. [0003] The shielding cover currently used is generally composed of two modules, namely a shielding frame (frame) and a shielding...
