Analysis of common problems of hardware talk mobile phone shielding cover

As the functions of mobile phones continue to become stronger, more and more attention is paid to the shielding effect. The following Xiaoshuo will talk about the common problem analysis of the mobile phone shielding cover: 1: The bending height of the mobile phone shielding cover is not general: the step distance is not adjusted, the more or less is sent; the bending punch inserts are shifted; the bending gap is one side The tight side is loose and leads to pulling of the material. Sometimes the same bending edge is high and the other is low, because the product swings or the position of the bending punch insert is wrong. 2; The word code of the mobile phone shielding cover disappears incompletely and unclearly, and the pitting disappears unclearly: the mold is not crushed; the height of the pitting insert of the word code is not enough or worn; the mold is pressed with waste products. 3. The flatness of the mobile phone shielding cover product is poor: the material is not too flat; the height of the bending edge is not uniform; the height and width of the bend on the bending insert are not uniform, which leads to the unbalanced stress and the material instability and deformation; the template is deformed and compressed Unexpectedly. 4. Mobile phone shielding cover assembly is too loose and too tight: there is a gap of 0.03-0.05mm on one side of the shielding frame and the shielding cover, the outer dimension of the shelf goes up to the upper limit, and the outer dimension of the cover goes to the lower limit. The assembly is loose 5. The mobile phone shielding cover is yellow: there are yellow blocks on the surface of the product, and some will become linear, mainly because the surface of the product is not cleaned or has turbid water stains after washing, and it cannot be completely dissipated during drying. , After high temperature, it turns into a slight white fog, severely from white to yellow, and some are stained by finger touch, which will turn yellow after a long time.
