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

2. The stain problem of the HW P40 pro project. The stain affects the yield rate of about 2.5% when the project enters mass production. Through the composition analysis, 80% is motor debris. After verifying the AA section, the three-vibration three-wash and dust-catching glue are introduced, and the special tear film Fixture (IR film), the overall bad stains have been reduced from 2.5% to 0.7%, reducing the loss by about 300,000 RMB per day
