1. Composition and Application
The shielding cover consists of legs and a cover body, with the legs and the cover body being connected in a movable manner; The hood has a spherical crown shape.
This component is mainly used in fields such as mobile phones and GPS to prevent electromagnetic interference (EMI) and provide shielding for components and LCM on PCB boards.
The material of the shielding cover is generally made of 0.2mm thick stainless steel and phosphor bronze, among which phosphor bronze is a metal shielding material that is easy to tin. When using SMT patches, the design of suction cups should be considered.
2. Material application
The shielding frame generally uses Cu-C7521-H [universal material], Cu-C7521-OH [soft material, for deep drawing] (nickel white copper, copper nickel zinc alloy), NickelSilver),t=0.2,0.3mm; The shielding cover is generally made of stainless steel SUS304R-1/2H [bending processing], SUS304R-1/4H [deep drawing use], t=0.15, 0.2mm, tin plated steel strip (tinplate), etc;
For soldering on PCBs, white copper and tin sheet can be used, and it is recommended to use white copper because it is better in soldering, heat dissipation, and steam.
