There are many different methods used to prevent EMI damage to the internal circuitry of devices and systems. So, today we are some techniques discuss the EMI prevention ………….
1) Twisted-pair implementations :
Twisted pair cables are made with both forward and return conductors twisted together within the same cable. This method of manufacturing cable eliminates any chance of EMI interference because the conductors within the wire cancel each other out. For extra protection in multi-pair cables, such as Ethernet, each pair is twisted together at a different rate, and the multiple twisted pairs are then twisted together.
2) Cautious wiring techniques :
The types of wires used and the placement of those wires can prevent certain devices and wires from interfering with each other. Fluorescent lights and AC electrical cables, for example, emit EMI, so when running network cable in or along walls or ceilings, avoid running them near ﬂuorescent ﬁxtures, and try to cross electrical cables at right angles, rather than follow them. Electronic components themselves may generate or be susceptible to EMI; however, their leads serve as the antennae that radiate or receive such interference.
3) SMD technology implementation :
Surface Mount Devices (SMDs) are electronic components that are designed to be soldered directly onto circuit boards, without legs. This technology minimizes EMI transmissions to and from such devices.
4) Electromagnetic shielding :
Shielding is used to prevent electromagnetic transfers from cables and devices by creating a conductive material protective barrier. For example, a shielded cable contains electromagnetic shielding within the cable that directly protects the inner core conductor from producing electromagnetic discharge.
5) Network Interference :
Network interference is the disruption of normal data transmissions over a network. EMI can cause intermittent network issues and can be avoided by applying EMI prevention techniques such as shielding, wiring techniques, and using twisted pair cables to connect network components.
