RFI/EMI Shielding-What is it?
RFI/EMI Shielding-What is it? RFI Shielding is essentially blocking radiofrequency electromagnetic signals in the radio frequency band of the electromagnetic spectrum. Left unchecked, these signals can disrupt the electrical circuits from working properly. Basically, RFI shielding involves the placement of barriers made of conductive and magnetic materials around the device, allowing it to function optimally. The name "shielding" means completely isolating the susceptible parts from the source of the RFI. The Effectiveness of the shielding depends on properties of the...

RF Shielding Curtains-Separation and Isolation!
RF Shielding Curtains-Separation and Isolation! RF Shielding Curtains are relocatable shields designed for isolating or separating areas from RF waves. Curtains can be made to the customer's specification of size, Shielding Effectiveness, and suspension method. The conductive metalized textiles and number of layers used in their manufacture determine the RF shielding properties of the curtain. RF Shielding Curtains can even be made to withstand weather, UV, and rough treatment with a "ruggedized finish"! RF Isolation is important in many areas and...

Pre-Compliance EMC Testing-Practical!
Pre-Compliance EMC Testing-Practical! No one likes to do the same job twice! It's not efficient because it is a true waste of time. Making sure the job's done right the first time is the best way to proceed. This is especially true in electronic components. Electric components are made up of multiple electronic devices, working together smoothly. Everyone knows that every electronic device has to pass EMC compliance testing before it can go to market. EMC is achieved when all...

Shielding RF/EMI allows Electronic Teamwork!
Shielding RF/EMI allows Electronic Teamwork! Electronic components consist of several electronic devices working together toward a common result. All electronic devices create electromagnetic fields. Electromagnetic fields can be the source of "noise" that can affect the function of another nearby device or devices in the component. Noise produces a "toxic effect" on the shared electronic environment of the component, making it function below its capability. In order for the devices to be "compatible" with each other, there must be standards...

Shielding Challenges in Electronic Vehicles!
Shielding Challenges in Electric Vehicles! Low-frequency magnetic fields are an issue in electronic vehicles. Low-Frequency fields are related to human health and safety. Specifically, low-frequency magnetic field exposure of the nervous system where the frequency is below 500KHz. Additionally, some electric control units of an electronic vehicle can be adversely affected by this phenomenon. Obviously, anything that effects the controls of an EV can decrease the safety of the vehicle. The low-frequency magnetic fields in an electronic vehicle are largely...

Personal Shielding-RF/EMI Shielding!
Personal Shielding-RF/EMI Shielding! We tend to think of RF/EMI Shielding in the electronics industry. RF/EMI can affect the function of electronic devices. Interference can reduce the operational efficiency of electronic devices. Human beings are also electronic devices. Many body systems are electronic in nature, potentially disrupted by RF/EMI. We live in a world with ever-increasing RF/EMI. Some of this RF/EMI is from nature. Natural RF/EMI includes lightning, solar magnetic storms, the auroras, and the Earth's magnetic field. The natural RF/EMI...

Electromagnetic Compatibility-when devices work smoothly Together!
Electromagnetic Compatibility-when devices work smoothly Together! Devices are like people, they work best when they're compatible. Electronic devices work best when they don't interfere with each other. Electronic devices can be interfered with in several ways. They can be "distracted" by RF interference emitted by nearby devices. This distraction is similar to a co-worker who is always talking. The background "noise" keeps work quality below its potential best. Devices that can be "distracted" are called "susceptible". The answer to susceptibility...
