According to the China National Intellectual Property Administration, Kunshan Hensun Electronics Co., Ltd. has applied for a patent entitled "A Pattern Making Method for Solar Screen Inspection Film", with publication number CN121893667A and filing date November 2025.

The patent abstract shows that the invention relates to a pattern making method for solar screen inspection film, including: segmenting lines in the original film pattern according to different line types; placing the first line type on the first layer and thickening the lines; placing the second line type on the second layer and filling the lines; merging the first layer and the second layer to obtain the target film pattern. Based on the grid electrode design of solar panels, lines of different types are thickened and filled separately to form the target film pattern, which is then used to produce inspection film sheets for subsequent comparison with the solar panel grid pattern. Using such film inspection tools in production can effectively monitor process quality, detect and reduce abnormalities in a timely manner, lower rework costs, and improve final product yield.

Data from TianYanCha shows that Kunshan Hensun Electronics Co., Ltd., established in 2002 and located in Suzhou, is mainly engaged in other manufacturing industries with a registered capital of 20 million RMB. According to big data analysis, the company has participated in 10 bidding projects, owns 1 trademark, 77 patents, and has obtained 10 administrative licenses.
