Key words:
The shielding frame and shield are tools used to shield electronic signals. The function is to shield the influence of external electromagnetic waves on internal circuits and the external radiation of electromagnetic waves generated internally.
Shielding frame and shielding cover
The tray for placing the shielding cover on the shielding frame has too much space for movement, which can easily swing during the placement of the shield, causing it to be difficult to extract. The material must be placed in the tray with about 1.0MM of space for movement. If it is too large, it may cause the material to swing, and if it is too small, it may not be possible to extract it. The size of the feeding point for the shielding frame and cover should be appropriate, and the feeding point should be in the middle of the material as much as possible. The size of the feeding point should be Φ 6.0mm, the larger the feeding point, the higher the stability and efficiency of the patch.
Shielding frame and shielding cover materials are materials used to shield magnetic fields. There are three types of magnetic shielding: static magnetic shielding, low-frequency electromagnetic shielding, and high-frequency electromagnetic shielding. In practice, different shielding materials are selected according to different situations.
Shielding is a device method in electrical engineering. In order to prevent interference from external electric fields, magnetic fields, or electromagnetic fields on internal equipment, or to avoid the impact of electromagnetic fields on the outside, the equipment is placed in a closed or nearly closed metal shell or metal mesh, which is called a shielding cover. In structural chemistry, the term shielding is borrowed to name the following effects. The repulsive effect of the inner electrons in an atom on the outer electrons reduces the effective attraction of the atomic nucleus to the outer electrons, which is equivalent to the inner electrons "shielding" a portion of the nuclear charge, hence the name "shielding effect". The magnitude of the shielding effect between electrons can be approximated by the shielding coefficient.

What principles should be followed when selecting hardware stamping parts
Hardware stamping parts use punches and molds to deform or break stainless steel, iron, aluminum, copper, and other plates or materials to achieve the required size and shape. If the material selection of hardware stamping parts is not appropriate, it is easy to produce defective products, leading to high costs and other reasons.
