Background

The mask is a means for shielding electronic signals. The function is to shield the influence of external electromagnetic wave on the internal circuit and the outward radiation of the internally generated electromagnetic wave. The shielding cover consists of supporting legs and a cover body, and the supporting legs are movably connected with the cover body; the mask body is in a spherical crown shape. The component is mainly applied to the fields of mobile phones, GPS and the like, and has the functions of preventing electromagnetic interference (EMI) and shielding elements on a PCB and LCM. The tray for placing the shielding cover has too large moving space, the tray is easy to swing during surface mounting, the suction cannot be realized, materials must be placed in the tray, the moving space of about 1.0MM exists, the swing of the materials is caused too large, and the materials cannot be taken too little. The size of a material taking point of the shielding cover needs to be proper, the material taking point is arranged in the middle of the material as much as possible, the size of the material taking point is preferably phi 6.0mm, the larger the material taking point is, the higher the stability of the patch is, and the higher the efficiency is. Shielding is one means in electrical engineering. Such a metal shell or mesh enclosure is called a shield enclosure in order to prevent interference of external electric, magnetic or electromagnetic fields with internal devices or to avoid interference of electromagnetic fields of devices with external enclosures. In structural chemistry, the term masking is used to name the following effects. The repulsion of inner layer electrons to outer layer electrons in atoms reduces the effective attraction of the atomic nucleus to the outer layer electrons, which is equivalent to that the inner layer electrons shield a part of nuclear charges, so the shielding effect is called. The magnitude of the shielding effect between electrons can be approximately expressed by the shielding coefficient.

Because the chip is at the in-process of using, the user mistake touches and can lead to the crooked adhesion of pin together to interconnect interference, more also can link together two pins of dust when using for a long time, lead to the interference damage, cause serious property economic loss, we have proposed a dedicated jam-proof type shield cover subassembly for this reason.
