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...

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. ...

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...

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...

Military uses for Conductive Textiles!
Military uses for Conductive Textiles! The Department of Defense has many uses for Conductive Textiles. Obviously, the military has many sophisticated electronic devices in their vehicles, whether planes, tanks, or boats. The lives of the soldiers depend on these devices working smoothly without any interference from RFI or EMI. Proper RF Shielding allows these devices to work together efficiently in a shared electromagnetic environment. Conductive textiles are the best shielding materials for vehicles due to their light...

RF Interference-Controlled by Shielding!
RF Interference-Controlled by Shielding! RF Interference (RFI) and Electromagnetic Interference (EMI) can wreak havoc with the function of electronic devices. In our wireless world, the amount of RF radiation present in our environment is always increasing. Add the man-made RF radiation to the natural forms of RFI and EMI such as snow, rain and electrical storms, solar flares, and the auroras and there's a whole lot of radiation going on around here! Three things cause an interference problem, a "noise...

Your RF Shielded Enclosure-Custom-Made!
Your RF Shielded Enclosure-Custom-Made! Almost every electronic device under production is unique! They all have one thing in common-they must pass EMC Final Compliance Testing prior to marketing them! The EMC Compliance Testing is based on different classes of accepted standards. The standards vary for each class of device. EMC Testing takes place in RF Shielded enclosures with low ambient levels of RF present. During EMC testing, devices are evaluated for the amount of RF radiation that they can perform...

EMC Final Compliance Testing-be Prepared!
EMC Final Compliance Testing-be Prepared! The Boy Scout Motto is "Be Prepared". That phrase is my cornerstone approach to everything! Applying it first in grade school and continuing from that time forward, that phrase readies me for day-to-day life and my profession. Likewise, my V Technical Textiles, Inc. experience confirms it works for every testing experience when applied wisely. Electrical devices and components must pass EMC Final Compliance Testing prior to marketing them. EMC Compliance Testing determines...
