What is the reason for the poor flatness of the shielding cover? How should it be solved? [Hardware]

As the shielding cover is a customized part, customers are more worried about production quality problems during use. This kind of customized parts is not as good as other electronic devices, and can be adjusted at any time to meet production. The more frequent reasons for the failure of the shielding cover are mostly due to deformation and poor flatness. Xiaoshuo will let you know what is causing the poor flatness of the shielding cover? 1. The fundamental problem is the mold problem. In the design, processing, and assembly, the actual process of the shielding cover in the production is not reasonably achieved, and the problem of deformation and flatness has already occurred in the production. 2. The problem of production quality control. The mold will wear out during the manufacturing process, and the raw materials will also be deformed individually, so the quality is not static during the production process. If the operator and the inspection can not find the problem in time and deal with the problem, it will also cause defective products. 3. Improper cleaning, especially for the brackets of some shielding covers, whose structure is relatively weak. During cleaning, the overlapping gravity and water resistance during cleaning will also cause defects. 4. Improper packaging. Regardless of whether it is pallet packaging or carrier tape packaging, the size of the packaging groove is more than 0.1-0.15mm larger than the shielding. It is too small to jam the material and too large to shake. When packing on a pallet, the gravitational force stacked up and down should be placed on the side of the pallet instead of being pressed into the shielding cover product. Hardware, 15 years of focus on the design and production of shielding cover, 20,000+ sets of mold production and production experience. The monthly processing capacity of 100+ sets of molds, the daily production capacity of 3 million strokes, the flatness of the protection within 0.07mm, and the 16 quality inspections are strictly controlled. It can quickly solve time-critical problems for you, solve the problem of poor flatness, and solve the problem of production quality. Choose, let you choose rest assured!
