Electronic Devices plus Great Shielding-EMC!
Electronic Devices plus Great Shielding-EMC! Electronic devices are great things, making so many tasks easier and more enjoyable for us! Sadly, they also create EMI and RFI emissions naturally. Unfortunately, some of these emissions affect other devices working in their shared electromagnetic environment adversely. Consider the analogy of an office, one employee talks loudly and makes it hard for the other employees to concentrate at their highest level. The talking employee is an "emitter" of EMI/RFI and the other employees...

Personal/Home Shielding reduces EMI Exposure!
Personal/Home Shielding reduces EMI Exposure! In today's wireless world, we endure constant exposure to RF waves. Though there is no absolute proof of health risks due to RF wave exposure, there is certainly concern regarding exposure. EHS (Electromagnetic HyperSensitivity), the name given to EMI sensitivity, involves nervous system symptoms. Symptoms include headaches, fatigue, stress, sleep disturbances, and skin irritation among many others. Many sufferers of EHS claim that their symptoms decline when they shield themselves from RF/EMI exposure. Personal Shielding...

EMC Compliance Test-Prepare your Product!
EMC Compliance Test-Prepare your Product! Every electronic device must pass EMC Compliance tests in order to be marketed. Preparing your product for this should be done from the start of the product's development until it is complete. The best way to be ready for this test is to test the device early and often during product development. Running an EMC Pre Compliance test at each crucial step allows discovery and correction of issues along the way. Obviously, this stepwise process...

Metalized Textiles-What are their Uses?
Metalized Textiles-What are their Uses? Metalized textiles were first used in various Shielding Applications. I can remember when an automobile FM radio mainly played static! Metalized textiles played a major role in protecting the radio from RFI from the other electronic components in the vehicle. The antenna brought in shielded clean signals to the RF shielded radio which were sent out to the speakers, allowing the music to be heard as it was meant to be heard. ...

Conductive Fabrics-Great Shielding Material!
Conductive Fabrics-Great Shielding Material! Shielding materials are usually needed in electronic devices to protect the devices from EMI/RFI which can adversely affect their performance. The more conductive the Fabric is, the better its shielding characteristics are. Obviously, fabric is typically lightweight and flexible, making it great for shielding in tight quarters. Engineers also love the lightweight, as products today are smaller and more portable than ever before. Lightweight is also important in the automotive, aerospace, military, and law enforcement markets,...

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...
