　　The shielding cover is the main product of our Dongguan Bosi Hardware. It is a tool used to shield electronic signals. Some people may be unfamiliar with this metal stamping part. The following editor will explain the shielding cover for everyone.

　　
The composition and application of shielding cover:　

The shielding cover is composed of outriggers and a cover body, and the outriggers and the cover body are movably connected; the cover body is spherical. This part is mainly used in mobile phones, GPS and other fields to prevent electromagnetic interference (EMI) and shield the components and LCM on the PCB board. The material of the shielding cover is generally made of 0.2mm thick stainless steel and white copper, of which white copper is a metal shielding material that is easy to be tinned. The design of the suction cup should be considered when using SMT patches.

Material application of shielding cover:

Generally, Cu-C7521-H [general material], Cu-C7521-OH [soft material, for deep drawing] (nickel cupronickel, copper-nickel-zincAlloy, NickelSilver), t=0.2, 0.3mm; shielding The cover is generally made of stainless steel SUS304R-1/2H [bending processing], SUS304R-1/4H [for deep drawing], t=0.15, 0.2mm, tin-plated steel strip (tinplate), etc.;

Copper-Nickel-Zinc Alloy and tinplate can be used for soldering on the PCB, and white copper is recommended, mainly because white copper is better in welding, heat dissipation and steam.

Design Considerations of Shielding Case:

The tray on which the shielding cover is placed is too large, and it is easy to swing when patching, resulting in failure to pick up. The material must be placed in the tray, and there is about 1.0MM of activity space. If it is too large, it will cause the material to swing. If it is too small, the material may not be picked up. come up.

The size of the pick-up point of the shielding cover should be appropriate. The pick-up point should be in the middle of the material as much as possible. The size of the pick-up point is preferably Φ6.0mm. The larger the pick-up point, the higher the stability of the patch and the higher the efficiency.
