The silicon steel sheet of the adapter of cell phone jammer

Most of the original thickness of the liner in the compressed 30% to 70% better results. Therefore, the proposed minimum contact surface within the concave point between the two opposite pressure should be sufficient to ensure that the gasket between the liner and has a good electrical conductivity. On the other hand, the pressure on the pad should not be so large that the liner is non-normal compression state, because at this time will result in contact with liner failure, and may produce electromagnetic leakage. The coil wrapping of the adapter of cell phone jammer has no oxidization, looseness and tilting.Separation requirements and gasket compression control for the gasket manufacturer's recommended range is very important, this design needs to ensure the gasket with sufficient hardness to avoid large bend between the washer fasteners. In some cases, may require additional fasteners to prevent the shell structure of some bending. Compression is also turning an important feature of the junction, such as location of the door or flapper. If the liner easily compressed, then the shielding performance with each rotation of the door down, then liner power required to achieve higher compression the same with the new gasket shielding performance. In most cases this is unlikely to do so requires a long-term EMI solution.The silicon steel sheet of the adapter of cell phone jammer has no oxidization, looseness and tilting. If the gasket by a shield or coated with a conductive layer made of plastic, then add an EMI gasket will not have too many problems, but the designer must consider many in the conductive pads on the surface, there will be wear and tear, usually metal liner coating the surface easier to wear. Grow over time this will reduce the wear liner junction of shielding effectiveness, and to the back of trouble makers. If the shield or gasket is a metal structure, then spray a polishing pad material can be added prior to the gasket surface of the wrap, just use conductive film and tape can be. If the bonding pads on both sides are using tape, you can use the firmware on the EMI gasket for mechanical fastening, such as with plastic rivets or pressure-sensitive adhesives (PSA), "C-type" liner. Here is the electrical performance of the adapter of cell phone jammer.Pad mounted on the side of the gasket to complete the EMI shielding. Liner and accessories currently available are very much shielding and cushioning products, including beryllium - copper fittings, metal cable (with or without elastic inner core), the metal mesh embedded in the rubber and directional lines, conductive rubber, and has a metal coating polyurethane foam pad and so on. Most manufacturers can provide shielding material liner to achieve a variety of estimates of the SE, but remember that SE is a relative value, but also on the porosity, pad size, pad compression ratio, and material composition. There are a variety of pad shapes, can be used for a variety of specific applications, including wear, sliding and hinged occasions. Many pads with adhesive or liner above, there fixtures, such as extrusion insert, insert or barbed pin devices. Various types of pads, the coating foam pad is the latest and most versatile products on the market one. Here is the high voltage testing of the adapter of cell phone jammer.Such pads can be made into a variety of shapes, thickness greater than 0.5mm, the thickness can be reduced to meet the UL seal combustion and environmental standards. There is another new type of liner that environment / EMI gaskets mix, with it can no longer use a separate sealing material, thereby reducing the cost and complexity of the shield.
