Application and function of shielding cover

Before talking about the application and function of the shielding cover, let's first understand the material of the shielding cover. The material application of the shielding cover: The shielding frame is generally made of Cu-C7521-H [general material], Cu-C7521-OH [soft material, pull Deep use] (nickel-nickel-nickel-nickel-zinc alloy (Copper-Nickel-ZincAlloy), NickelSilver), tu003d0.2, 0.3mm; the shielding cover is generally made of stainless steel SUS304R-1/2H [bending processing], SUS304R-1/4H [pulling] Deep use], tu003d0.15, 0.2mm, tin-plated steel strip (tinplate), etc.; for soldering on the PCB, nickel silver and tinplate can be used, and it is recommended to use nickel silver, which is mainly because the nickel silver is being welded. , Heat dissipation and steam are better. The scope of use of shielding covers: PCB circuit boards, set-top boxes, mobile phones, telecommunications equipment, etc. The role of the shielding cover: mainly to block electromagnetic waves outside the cover, avoid the harm of electromagnetic radiation, and prolong the service life. Several shielding covers are shown in the following picture: Dongguan Precision Electronic Technology Co., Ltd. has been committed to precision metal stamping parts, shielding covers, battery connection sheets, nickel sheets, shrapnel and other products for 30 years. All the company's production equipment is imported from Japan and Taiwan, and the company has passed TS16949, ISO9001, ISO14000 management system certification. He is good at technically overcoming high-precision, highly difficult and complex hardware and reducing the manufacturing cost of large-scale stable production of hardware.
