In the recent past, electronic engineers have been facing challenges when designing electronic components and devices due to the increased amount of electromagnetic interference. Operating frequencies of electronic devices have become much more complex, which makes components more susceptible to EMI interference. All wireless electronic systems are vulnerable to electromagnetic interference. EMI is a disruptive emission that emanates from electronic components and natural phenomena. This radiation negatively effects circuit performance and can limit a component from working properly. In theory, all negative electromagnetic interference can be mitigated with the proper interference. All shielding designs are structured to reduce radiation to a nominal level.
EMI comes in two main sources: RF front end, and internal digital circuits. Most circuit board designers have to create a component that produces the lowest amount of radiation, while still operating. All cell phones, computers, tablets, and other portable devices emit and EMI, and need special shields to keep the radiation from disrupting their signals. The best way to control EMI is through a difficult task, but it can be accomplished by limiting the amount of radiation coming from a specific source. This is accomplished with ground planes, efficient wiring layouts, and shielding gaskets.
Shielding gaskets are used as effective methods to completely seal the device from emitting and receiving EMI. In essence, gaskets stop EMI from disrupting electronic devices, and prevent them from leaking out EMI. If an electronic component is improperly shielded it will emit EMI radiation, which will disrupt other devices.
The most cost-effective shielding is used in tandem with other suppressive techniques and devices. Gaskets are used and the devices are grounded, filtered, and designed with a circuit board that minimizes loop area. If a designer leaves the shielding design last, the component generally has a less efficient and cost-effective system design.
EMI shielding gaskets are typically installed during the design stages, in order to isolate a certain section of a system from another. Shielding gaskets are mostly implemented between the mating surface and the shield housing of an electrical system. These gaskets are fashioned to meet a wide range of complex applications and can even be customized for specific roles.
If you are interested in learning more about EMI, shielding gaskets, or shielding theory in general, contact a local EMI shielding gasket manufacturer for more information. Choosing the right shielding method is an important decision that should be guided by a professional!
