Dongguan shielding cover manufacturer, the reason for the yellowing of the shielding cover + 16 strict quality inspections

Dongguan shielding cover manufacturers, in our actual application, the shielding cover will encounter the phenomenon of yellowing on the surface. It seriously affected the appearance, quality, and use of customers. Xiaoshuo compiled some information, and let’s work with you to understand what causes the shield to turn yellow? 1. The production of the shielding cover does not control the raw materials in place, so that the material of the shielding cover, before the production, the foreign cupronickel material has been naturally oxidized, and the phenomenon of yellowing has occurred. 2. The cleaning after the shielding cover is produced, and the improper combination of the cleaning solution prescription will cause 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 over the furnace at high temperature. 4. The storage environment is not up to standard. In general, metal materials will have natural oxidation. If the storage environment is not up to standard, it will accelerate the oxidation of the shielding cover, thereby accelerating the yellowing of the shielding cover. Hardware, 15 years of focus on Dongguan shielding cover manufacturer, 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 shielding cover 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!
