In order to understand the reason behind the increasing demand of EMI and RFI shielding, we first need to understand what these two actually mean. EMI refers to electromagnetic interference and when associated with radio frequency, it is known as radio frequency interference (RFI). These kinds of interferences can generate various disturbances in the electronic devices. As a result, such disturbances can restrict the effectiveness of the circuit present within the device.
Basically there are two kinds of EMI and RFI interferences:
Broadband: This originates from sources such as power lines and other unintended radiations.
Narrowband: Broadly narrowband originates from radio, mobile phones, televisions and other intended transmissions.
With the above mentioned interferences, it is important for industries to find solutions to protect their equipment against them. And to do so EMI and RFI shielding is used. These shields are manufactured out of pure metals namely nickel, silver and copper in order to eliminate the RFI and EMI interference. Undoubtedly you can use sprays, paints and coatings to protect your devices from EMI and RFI induced interference but it is equally essential to be certain that your equipment isn’t causing any such interference. EMI gaskets can be used to tackle the radiation of frequency waves and avoid such waves from interfering with related electronic sources. Because we are part of this technological world, it is necessary that we make sure no amount of interference is caused by electronics. And to do this, various equipment are used such as gaskets, shielded windows, conductive tapes, etc.
Below given are some reasons as to what let to increasing demand of EMI and RFI shielding:
- The ongoing research to develop and establish 5G networks has tabled down the possibilities of expansion of interferences. And in order to overcome these interferences, EMI and RFI shielding is in demand because it is a productive method to meet the need.
- Increase in demand for autonomous and semi autonomous vehicles has highlighted the need for proper functioning of sensors and other electronic components. Shielding is a perfect method to make sure of that. Right functioning of electronic components is essential for the safety of passengers and to be certain of that shielding is must.
- Modern day cars and trucks possess upto 100 networked microprocessors having 150 million lines of code along with numerous supporting elements. Furthermore these vehicles include various features such as Bluetooth, navigation system, handsfree feature, touchscreen feature, parking assistance, forward collision warning, locking system and automatic emergency braking. All of these produce interference and can even get affected by electromagnetic radiations. In order to avoid all of this it is ideal that you safeguard these systems thereby, opting for EMI and RFI shielding.
As electronic devices are gaining popularity day by day in various industries such as aviation, medical, automotive, etc, the possibilities of expansion of radio or electromagnetic frequency interference is also increasing. This further leads to growing need of EMI and RFI shielding in order to protect the concerned devices from suffering due to such interferences.
