[Hardware] Shield manufacturer talks about the role and influence of foreign cupronickel mobile phone shielding

Shielding covers are commonly used on motherboards of various mobile phones, routers, transformers, etc. The main function of the shielding cover is to prevent electromagnetic interference (EMI) and shield the components and LCM on the PCB. Because of this, the design of the shielding cover manufacturer is good or bad. Will directly affect the overall performance of the phone. As the market continues to change and products continue to upgrade, many machines have begun to use stretch shielding (single-piece stretching or two-piece shielding bracket stretching). Compared with the ordinary two-piece type, the advantage of stretching shielding cover is Less leakage and better shielding performance. Material application of shielding cover manufacturers. Bracket: Generally, the bracket can be used: Cu-C7521/7701 (nickel white copper, nickel silver, Nickel Silver), tin-plated steel strip (tinplate), etc. It is recommended to use nickel silver; reason: nickel silver is better in terms of welding, heat dissipation and steam. The cover cover is generally made of stainless steel SUS304 (R-1/2H. The shielding cover can be made of 0.1 or 0.15mm thick material, try to use 0.15mm; the bending type shielding bracket should use 0.20mm thick material as far as possible, and use less 0.15mm thick material ; The tensile shielding bracket must be made of 0.2mm thick material. The clearance between the shielding bracket and the shielding cover in the X and Y directions is 0.05mm; the top of the Z direction also needs to reserve a gap of 0.03~0.05mm to avoid shielding frame holes After the position is moved down, the shielding cover buckle is not in place; hardware, 15 years of ingenuity, focusing on shielding manufacturers. The daily production capacity of 3000000 strokes. It can be sampled in 2 days, mold out in 4 days, and delivery in 2 days. The flatness of the shielding cover is controllable Within 0.07mm. It is your reliable partner in terms of time, quality and output.
