1.HW P40 pro项目SFR问题，项目前期发现模组存在正场曲约2

1. The SFR problem of HW P40 pro project. In the early stage of the project, it was found that the module had a positive field curvature of about 20um, and there were also low peak values ​​and single-line drift. After investigation, the largen lens itself had field curvature, and the H unidirectional field curvature was about 14um. The normal control is 7um. By using the P9 machine to select the lens to control the 0.85F peak value, the AA is controlled according to the on-axis value of 47, and the 8-wire control knife edge is changed, and the defect is reduced from 7% to 0.2%; <br>2. The stain problem of the HW P40 pro project, The project enters mass production and the stains affect the yield rate of about 2.5%. Through the composition analysis, 80% is motor debris. After verifying the AA section, the introduction of three vibrations and three washing and dust-trapping glue, and the introduction of a special tearing film fixture (IR film), the stain is bad The overall decrease from 2.5% to 0.7%, reducing losses by about 300,000 RMB per day

1.HW P40 pro项目SFR问题，项目前期发现模组存在正场曲约20um,另存在峰值低及单线飘现象，经过排查largen镜头本身存在场曲，H单方向场曲约14um，镜头来料正常管控为7um，通过使用P9机台挑选镜头管控0.85F峰值，AA按轴上值47管控，并更改8线管控刀口，不良由7%下降至0.2%；<br>2.HW P40 pro项目污点问题，项目进入量产污点影响良率约2.5%，通过成分分析，80%为马达碎屑，通过验证AA段导入三振三洗及捕尘胶，并导入专用撕膜治具（IR膜），污点不良整体由2.5%下降至0.7%，减少损失每日约300000RMB

1. For the SFR problem of HW P40 Pro project, it was found that the positive field curve of the module was about 20um, In addition, there are low peak value and single line drift phenomenon. After investigation, largen lens has field curvature, H single direction field curvature is about 14um, and the normal control of lens incoming material is 7um. Through the use of p9 machine to select the lens, control the peak value of 0.85f, AA according to the value of 47 on the axis, and change the 8-line control knife edge, and the defect is reduced from 7% to 0.2%;<br>2. For the stain problem of HW P40 Pro project, when the project enters mass production, the yield is about 2.5%. According to the composition analysis, 80% is motor debris. Through the verification of AA section, the introduction of three vibration three washing and dust collecting glue, and the introduction of special tear film fixture (IR film), the overall bad stain is reduced from 2.5% to 0.7%, and the loss is about 300000 RMB per day<br>
