What materials are needed to make shielding covers?
As we all know, shielding covers are mainly designed to prevent electromagnetic interference and can shield components and LCM on PCB boards. Widely used in the market are: fixed shielding (directly soldered to the PCB board with SMT), and removable shielding cover (combined with structure and LCM or directly buckled with the protrusions on the shielding cover on the shielding frame).
The materials used for shielding covers are generally: stainless steel, galvanized steel strip, nickel silver, brass, etc., but nickel silver is the most effective among them. Because it has the advantages of good shielding effect, electrical conductivity, fatigue resistance, and oxidation resistance, especially nickel silver has deep drawing performance, which meets the high demand for the production of shielding covers. Therefore, although it is more expensive than stainless steel and other materials, it is generally Some people still choose nickel silver as the raw material for the shielding cover.
