What factors should be paid attention to when purchasing the nickel silver shielding cover of mobile phones [Hardware]

Many purchasing friends in the mobile phone industry generally pay attention to several points, worrying about the price increase of the main components and worrying about the shortage of goods. I'm worried that the customized materials can't keep up with the progress, that the shielding cover can't keep up with the mold opening time, and the production can't keep up with the speed. Generally, what factors should be paid attention to to improve work efficiency and work quality? As a customized part on the mobile phone motherboard, the shield does play an important role. The process of most companies is to draw the board first, and then draw the shielding cover after the motherboard is determined to be okay. Once confirmed, the prototype test is urgently needed, and the test is successful, and the mold is urgently needed, and the mold is opened, and mass production is urgently needed. These are all situations where there is no problem at all. If there is something wrong with the shielding cover template or mold or mass production, it is the same as the production line reminder, the plan reminder, the purchase reminder... Reliability is the key. When a partner has thought about all of your problems before doing it, they have already formed a standard process, what else can you worry about?
