Regarding the shielding cover of the set-top box, the shielding cover is a tool used to shield electronic signals. The function is to shield the influence of external electromagnetic waves on the internal circuit and the electromagnetic waves generated inside to radiate outwards. The following decimals take everyone to understand the shielding cover: The shielding cover is composed of legs and a cover. The legs and the cover are movably connected; the cover has a spherical crown. This component is mainly used in mobile phones, GPS and other fields to prevent electromagnetic interference (EMI) and shield the components on the PCB and LCM. The shielding frame generally adopts Cu-C7521-H [general material], Cu-C7521-OH [soft material, for deep drawing] (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 [for deep drawing], tu003d0.15, 0.2mm, tin-plated steel strip (tinplate), etc.; used for welding on PCB The nickel silver and tinplate can be used for the above, and it is recommended to use nickel silver, mainly because the nickel silver is better in terms of welding, heat dissipation and steam. Hardware, 15 years of focusing on set-top box shielding, 20,000+ sets of mold custom processing and production experience, monthly 100+ sets of mold processing capacity, 3 million punching production capacity per day, stamping accuracy up to 0.01mm, and 16 quality inspections strictly. It can quickly solve time-critical problems for you, solve stamping accuracy problems, and solve mass production quality problems. Choose, choose rest assured!
