Use of antistatic packaging bags

The devices in some factories are qualified and use antistatic packing bags, but when they are transported to the customer, some PCB boards or devices can not work properly. The reason is that although the anti static packaging bag itself is not easy to produce static electricity, it can not shield the external ESD. For example, in the course of transportation, the handling machine is static. The electrical discharge of the machine model (MM) may occur when the electricity is charged. When loading and unloading the workers with static electricity, the human body model (HBM) or the electrostatic discharge of the human metal model may occur. Therefore, the surface resistance of the ordinary antistatic packaging bag can not be used to shield the external ESD. For this kind of device, the antistatic screen should usually be selected. Cover bags. The anti static shielding bag and not only have all the anti-static performance of the anti static packing bag, but also the electrostatic discharge ESD and the external electromagnetic radiation shielding performance of the external personnel and equipment. It is composed of excellent multi-layer electrical conductivity and material, usually opaque. The price of the antistatic shielding bag is higher than that of the antistatic packaging bag. It can be used for packaging of sensitive devices, which is important for anti-static and electromagnetic interference. Other properties: electromagnetic interference attenuation, cutting resistance and water vapor permeability are all better than those of antistatic and antistatic packaging.
