Minimizing RF Radiation Exposure!

The Vital Role of RF Shielding!

The Vital Role of RF Shielding!  In our increasingly interconnected world, the reliance on wireless technology has grown exponentially.  From smartphones and IoT gadgets to 5G networks, these innovations have made our lives more convenient and efficient.  This proliferation comes with a new challenge:  managing the radio frequency (RF) spectrum effectively.  RF Shielding is the practice of using materials and design to block or reduce electromagnetic radiation in the RF spectrum.  Its primary purpose is to prevent electromagnetic interference (EMI)...
Roles for Conductive Textiles in Electronic Vehicles!

Shielding EVs- try Conductive Textiles!

Shielding EVs-try Conductive Textiles!  When it comes to shielding Electronic Vehicles (EVs) from Electromagnetic Interference (EMI), conductive textiles offer several advantages based on their structure.  These thin, lightweight, and flexible materials are perfectly designed to mitigate EMI while considering the unique requirements of EVs.  Conductive metalized textiles provide design flexibility, allowing them to conform to various shapes and contours within an EV.  This versatility enables engineers to customize shielding solutions for complex areas.  Conductive textiles are great in tight spaces! ...
Benefits and Process of Pre-Compliance EMC Testing!

Pre-Compliance Testing-great Development Tool!

Pre-Compliance Testing-great Development Tool!   The same is true in electronic product development.  All new electronic products must pass EMC Compliance tests to determine their ability to function properly in our device rich world.    Every device emits an electromagnetic field and every device has to work flawlessly in the same shared electromagnetic environment.  RFI/EMI emissions can affect the device's performance.  There are RFI/EMI emission standards for every class of device so that they don't adversely affect the other devices in...
Need a RF Shielded Enclosure? See VTT!

RF Shielded Enclosures have many Applications!

RF Shielded Enclosures have many Applications!  In our increasingly interconnected world, the need to manage environmental electromagnetic interference grows daily.   RF Shielded Enclosures, also known as Faraday Cages, play pivotal role in achieving this objective across several industries.  These unique structures are specifically designed to block Radio Frequency (RF) and electromagnetic radiation, serving many purposes.  Today, we will delve into the key applications of RF Shielded Enclosures and the industries that depend on them.  RF Shielded Enclosures form the cornerstone of...
Conductive Textile's role in Automotive Innovatiion!

Conductive Textile’s role in Automotive Innovation!

Conductive Textile's role in Automotive Innovation!  Automobiles are becoming increasingly dependent on electronic devices.  Where you find electronic devices, you will often find conductive textiles.  The initial role for conductive textiles in automobiles was shielding the radio from RFI, allowing the radios to play music clearly.  Amazingly, one of the primary applications in the automotive industry is still electromagnetic interference (EMI) and Radio-frequency interference (RFI) shielding.  Due to ever the ever-increasing number of electronic components in vehicles, ensuring smooth operation...
Pre-Compliance EMC Testing-many Benefits!

VTT Helps during “Testing Times”!

VTT Helps during "Testing Times"!  We all go through "Testing Times" in our lives.  In the electronic business, we think of product development as a very important "testing time".  New electronic devices must undergo and pass Final Compliance Testing prior to marketing.  VTT believes that the most important testing is Pre-Compliance EMC Testing.  Performing EMC testing early and often during development allows you the luxury of building EMC into your device during a step-by-step development process.  Correcting EMC issues during...
Nothing is "simple"-anymore-needs Change!

Nothing is “simple” anymore-needs Change!

Nothing is "simple" anymore-needs Change!  When I first came to VTT, our manufacturing product line was fairly simple.  RF Shielded Enclosures, RF Shielding Curtains, RF Shielding Garments were about it!  Today, we find that our customers are always finding new and different needs for our conductive textile products.  An RF Shielded enclosure has become a "suite" of rooms with more isolation than ever.  Requests for Foyers, removable walls, are routine requests rather than unusual.  RF Shielding Curtains are now "arrays...
Megastructures-RF Shielded Enclosures for Giants!

RF Shielded EMC Testing Enclosures-Size Matters!

RF Shielded EMC Testing Enclosures-Size Matters!  Electronic devices come in all sizes.  All of the devices require EMC Compliance Testing in order to be marketed.  This testing determines whether the device can work effectively in a shared electromagnetic environment.  All devices emit RFI radiation and electromagnetic fields.  These emissions can adversely affect the function of the other devices.  The problem boils down to two terms, emissions or susceptibility.  The RF emissions of an electronic device must meet certain applicable standards. ...
Conductive Textiles help make Travelling Safe!

Conductive Textiles help make Travelling Safe!

Conductive Textiles help make Travelling Safe!  Planes, trains, and automobiles depend on conductive textiles in many ways.  They keep the driver or pilot aware of the engagement of safety restraints by the passengers before beginning the trip.  If you drive automobiles, you are well aware that there are sensors present in the steering wheel that determine if the driver is in proper position and paying attention to his surroundings.  If the car wanders in its lane, sensors notice this and...
The Remarkable Evolution of EMC!

RF Shielding creates Device Compatibility!

RF Shielding creates Device Compatibility!  Everyone knows some people who are very talented at what they do, but they can't work together!  The mere presence of the two of them in the same room ruins the work environment. The same thing is true of electronic components, electronic devices do jobs well.  When the components have to work in a shared electromagnetic environment, they have to be compatible.  With people, it's their personalities that can make them incompatible, unable to work...
