EMI shielding and suppression are used shell gap shielding the way to achieve, most of the time following these simple principles can help to achieve EMI shielding: at the source to reduce interference; by shielding, filtering or ground isolation circuit to generate interference and enhance sensitive circuits, such as anti-interference ability.
Jietai two, the most serious leaks; area of small and large size of the largest degree-line electromagnetic leakage is still large. Figure 4 shows a diagram of a typical cabinet,Pioneer cell phone jammer group tries to know about demand of customers and environment in the round. The above apertures is divided into four categories: chassis (rack) chassis (cabinet) of such joints seam though small in size, but the degree of its maximum line size is very large fracture length, due to maintenance, open constraints, resulting in the electronic equipment in the sewing class to become the largest category of difficult mask apertures, conductive pads, and other special shielding material can effectively suppress electromagnetic leakage such apertures shielding design is the key: a reasonable choice of conductive gasket materials and appropriate control the deformation of conductive gasket materials to choose a reasonable and appropriate deformation control vent hole area and maximum class size of a large line of degree, air ventilation hole design is the key to the choice of components and assembly of structural design. to meet the ventilation performance conditions, the screen should be used as mask ventilation, high efficiency components for structural design. Watch and display hole hole hole in the type area and maximum wire size of a large degree, the light shielding design is the key to the choice of materials Shielded light with the choice of materials and assembly of structural design. with the structural design.Pioneer cell phone jammer company seizes the product performance and features. connectors and chassis joints such seam line area and the maximum degree of size are not large, but at high frequencies lead to connectors and chassis contact resistance increases rapidly, making the shielded cable common-mode conducted emissions become larger, often leads to the emergence of excessive emission of radiation equipment, this should be conductive rubber connector conductive pad. In summary, inhibition of apertures design features summarized as: a reasonable choice shielding materials; reasonable choice shielding materials; rational design and installation of interconnect structure. rational design and installation of interconnect structure.

Pioneer mobile phone jammer company has condensed more scientific and technological resources in the research development. Electromagnetic interference shielding (EMI shielding) Electromagnetic Compatibility (EMC) refers to "a device, equipment or system performance, it can make it work in their own environment and without any other equipment in this environment a strong electromagnetic interference (IEEEC63.12-1987). "transceiver for wireless devices, the use of non-continuous spectrum can be part of the EMC performance, but many of the examples also show that EMC is not always able to do. For example, in notebook computers and testing devices, printers and desktop computers as well as between mobile phones and medical equipment and so has the high-frequency interference, such interference we called electromagnetic interference (EMI). All electrical and electronic equipment, will have intermittent or continuous voltage and current changes, sometimes quite fast rate of change, this will result in a different frequency bands within or between the electromagnetic energy, while the corresponding circuit will be launched this energy to the surrounding environment. Pioneer cell phone jammer company now owns powerful technical strength.There are two ways to enter or leave a circuit: radiation and conduction. Signal radiation by the shell seam, groove, openings or other gap leak; and signal transduction is by coupling to power, signal and control line to leave the shell, in an open space free of radiation, resulting in interference.
