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...

Rack Systems protect your Server’s Data!

Rack Systems protect your Server's Data!  We live in a "wireless world", so many transactions take place over the airwaves!  That's a nice convenience of living in a digital world!  Life is simpler when we can take care of so many of our responsibilities without leaving home.  That ease comes with a potential cost.  There are many people who "earn" their livings by stealing or misappropriating digital information.  We often hear of people who have had terrible experiences such as...
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...
Metalized Conductive Textiles Applications-Variety!

Technical Embroidery-Conductive Yarn “Wires”!

Technical Embroidery-Conductive Yarn "Wires"!  Smart clothing requires durable conductive wires!  I'm asking you to "think outside the box" when it comes to the term "wire".  In the case of clothing a classic "metal wire" leaves quite a bit to be desired.  It is rigid and doesn't like the movements of the human body.  Flexing a metal wire leads to stress cracks, and ultimately failure of the wire.  Additionally, metal wires in clothing are not exactly "comfortable" for the wearer, we...
Navigating EMC Testing

EMC Compliance Testing-what’s the Point?

EMC Compliance Testing-what's the Point?  Every electronic device must pass EMC Compliance Testing to make it to the market!  The reason for this requirement is to lessen the amount of RFI/ EMI in our environment.  More importantly, it is to lessen the RFI and EMI in our environment that adversely affects the function of other devices present in the shared electromagnetic environment.  All electronic devices emit RFI/EMI.  In general, electromagnetic interference doesn't cause a decrease in function of the devices...
RF Shielded Enclosures- Choose your Series!

RF Shielded Enclosures-Testing at Home!

RF Shielded Enclosures-testing at Home!  Preparing for Final Compliance EMC Testing is difficult.  One of the best ways to prepare for this test is to prepare your product during development.  Testing your product in your home environment during development builds EMC into your device from the start and is the best way to proceed.  Pre-Compliance EMC Testing can be done easily at your development site.  It actually saves time in development, by intercepting EMC issues along the way rather than...
Megastructures-RF Shielded Enclosures for Giants!

Large RF Shielded Enclosures-Giants!

Large RF Shielded Enclosures-Giants!  I always say that VTT fabricates RF Shielded Enclosures to satisfy the needs of our customers, whether it's as small as our 3D Pouch, our "small test lab", or a much larger one.   This year, we are receiving orders for "Testing Megastructures", very large testing enclosures.  RF Shielded enclosures provide the low ambient RF environment required for Pre-Compliance EMC testing.  The size of the testing enclosure is typically dependent on the size of the Device Under...
RF Shielded Bags-Protection and Security!

Small RF Shielded Enclosures-Petite!

Small RF Shielded Enclosures-Petite!  RF Shielded Enclosures come in all sizes, from Megastructures to Gusseted bags!  VTT is able to create RF Shielded Enclosures to satisfy their customer's needs.  Electronic devices come in all sizes and must pass EMC Final Compliance Testing in order to be marketed.  The Gusseted Bag is a small RF Shielded Test chamber that provides the low ambient RF environment required to perform EMC Testing.  The bag, fabricated using conductive textiles, creates a Faraday Cage, blocking external...
Versatile RF Shielded Curtains-many uses!

Require Isolation- RF Curtains work!

Require Isolation-RF Curtains work!  When RF Isolation is necessary during an electronic system diagnosis and repair there often isn't a large enough RF Shielded Enclosure present.  Isolation may be possible by using an array of several RF Shielded Curtains.  This approach facilitates diagnosis and repair in situ, where it originally arose.  There are many situations that require RF isolation.   Warehouses and storage facilities where inventory management involves constant monitoring with RFID.  In order to avoid " RFID crosstalk" between the...
