Four Tips to get most out of EMI Shielding

EMI shielding has emerged to lessen the number of electromagnetic interferences caused by incoming and outgoing electrical radiations. Electromagnetic shielding is applied on electronics to prevent them from damages caused by different frequencies of electromagnetic waves. Without EMI shielding, many of the electrical gadgets and electronics will become unsafe and unusable. Hence, electromagnetic shielding is necessary for maintaining the performance and productivity of the electrical devices.

Moreover, many electronic designers are constantly working towards recognizing the impact of electromagnetic energy on the application environment.

Here are some tips to get most out of the EMI shielding. Read on and discover some essential tips and facts on EMI shielding.

  1. Usage of Shielding Gaskets:

Choosing the cost-effective shielding gaskets over conducting rubber compounds is the major concern of folks. In-place gasket shielding is both cost-effective and expensive. While it is expensive from a manufacturing point of view, but in terms of material and form, it is considered to be a cost-efficient method.

A major reason for ineffective gasket shields is their faulty installations. This generally happens due to wrong placement of gaskets over the surfaces. To avoid such problems, the gaskets should be placed rigidly over constructive and recessed platforms.

  1. Removal of Heat from the Components of EMI Covers:

Heat is likely to be produced in various components of EMI shielding gaskets and apertures. Hence it is significant to remove this to ensure proper function of the EMI systems. Ventilation holes along the top surface of the shielding cans help in removing excessive heat.

Moreover, the usage of power chips in shielding assures a high thermal practice. To ensure better performance with minimum heat emissions, these power chips ought to be applied before attaching the electromagnetic interference covers with the circuit boards. Hence, heating the lids above 60 degrees before attaching them is a good practice as slightly higher temperature helps in limiting the air trapped gaps between the EMI shielding systems.

  1. Dealing with the Leakages:

Leakages are yet other problems to deal with electromagnetic shielding systems. Leakages tend to affect the functionality of the shielding gaskets and apertures. As EMI leaks are prominent, hence it is crucial to seal the access panels and cable openings.

Moreover, the leakages should be inspected at regular intervals and always be treated with the help of conductive caulks.

  1. A thorough See through of Design and Layout:

Essentially, design and layout of the EMI systems are significant for smooth performance and functioning of the system. Hence, a see-through the window is requisite at regular intervals and should be done with a blackened mesh. This is so because; a finer mesh and darker mesh material are helpful for ensuring a better performance of the EMI shielding.

RFI and EMI shielding are incredibly important to avoid any interruptions and malfunctioning of the electronic devices caused by electromagnetic waves. These electromagnetic interferences emit waves that adversely affect the electrical circuits, leading to poor performance of the electronics.


EMI signals are invisible ghosts that tend to haunt about any location where there is a wide range of electrical devices. EMI shielding essentially prevents the electronics from electromagnetic waves. To know how to get most out of EMI shielding, click here.
