Module shielding cover manufacturers, what is the reason for the yellowing of the shielding cover + 15 years of experience manufacturers will take you to analyze

The manufacturer of module shielding cover hardware said that in our actual application, the surface of the shielding cover often encounters yellowing. It seriously affected the appearance, quality, and use of customers. Xiaoshuo has compiled the following information and will work with you to understand what causes the shielding cover to turn yellow: 1. The raw materials of the shielding cover are not properly controlled in the production of the shielding cover, so that the material of the shielding cover is natural before the production. Oxidation produces a yellowing phenomenon. 2. The cleaning after the shielding cover is produced, and the improper combination of the cleaning solution causes a chemical reaction to the nickel silver material, causing the shielding cover to turn yellow. 3. In the soldering process of the SMT factory, some formulas are not matched properly, which causes the yellowing of the surface of the shielding cover when the shield is overheated at a high temperature. 4. The storage environment is not up to standard. Under normal circumstances, metal materials will produce natural oxidation. If the storage environment does not meet the standard, the oxidation of the shielding cover will be accelerated, thereby accelerating the yellowing of the shielding cover. Hardware, 15 years of focus on module shield manufacturers, 20,000+ sets of mold customization production experience, 2 days for proofing, 4 days for mold making, and 2 days for delivery. The flatness of the shield is controlled within 0.07mm, the daily production capacity is 3 million strokes, and 16 quality inspections are strictly controlled. It can quickly solve the urgent problem of time when choosing the shielding cover, solve the problem of flatness, solve the problem of production quality, let you choose, choose to rest assured!
