Why Choose EMI Shields Over EMI Coating?
Coatings and shields are an important part of electronic devices, printed circuit boards (PCBs), and so on. Both these techniques offer protection to the board components, wires, and so on from electromagnetic interference (EMI) as well as other external parameters. However, coating is different from shielding. Coating is done in the form of paints or sprays, while EMI shields are...

Its ability to protect electronics from EMI makes it an invaluable tool for various industries where high-level interference needs to be neutralized or avoided. Overall,...
Aluminum EMI Shielding: Importance and Challenges
EMI shielding helps protect electronic devices, systems, and components from electromagnetic interference. This type of interference can come from a variety of sources, like power lines, radio waves, and electrical appliances. By using EMI shielding methods and techniques, these devices and systems can properly function without any interference. This kind of protection is extremely important in many industries such as...
Use of Stainless Steel in EMI Shielding vs. Plasticized Tin
Electromagnetic interference (EMI) whether on board or device level must be either managed or eliminated. This is because it interferes with the functioning of the PCB or device and may even damage it. Today many EMI shielding techniques are used to mitigate EMI. Although these shielding techniques differ in terms of application and impact, the only requirement most users focus...
Know Some Popular EMI Shielding Techniques
Printed circuit boards nowadays are complex with multiple layers, components, and so on. Additionally, the size of these boards is shrinking, these components need to be mounted carefully in a small space. All of this makes them susceptible to EMI, and more so in case of design-related issues. Electromagnetic interference (EMI) or noise occurs when signals from two or more...
EMI Shielding Tape vs. Board Level Shields
Electromagnetic interference (EMI) or noise is a phenomenon that occurs when signals from two components in a circuit or two devices on different circuits clash with each other. This leads to crosstalk or noise which may hamper the functioning of the circuit and subsequently the entire device. Hence, this needs to avoided at all costs. EMI is commonly produced in...
Know About EMI Coupling Methods and Tackling Unintended Coupling
When current flows in a charged conductor, it produces an electromagnetic field at about 90 degrees to the conductor. This current changes the direction of flow a number of times and at a particular frequency. These electromagnetic lines may pass through another conductor in the same circuit which produces voltage. This is the basic concept of coupling which transfers energy...
EMI Filtering Vs. Board Level Shielding
Electronic devices are a part of everyday life and hence it is essential that they have good quality PCBAs incorporated within for proper functioning. Often at device as well as PCB level, signals in the form of electromagnetic waves mix up which creates noise and may alter the functioning of the device. This interference must be removed. There are various...
