Metalized Textiles Questions-VTT has the Answers!
Metalized Textiles Questions-VTT has the Answers! V Technical Textiles, Inc. has the world's largest inventory of Metalized Textiles. VTT is the marketing and sales arm of our German partner, Shieldex. VTT prides itself in this strong relationship. VTT has input into the design of these unique textiles. Metalized Textiles were originally used in RF Shielding in automobiles. Their primary use was to stop RF interference with electrical components. In the last decade, uses for metalized textiles have grown exponentially. The...

Your own Test Lab-an RF Shielded Enclosure!
Your own Test Lab-an RF Shielded Enclosure! Best practice suggests Pre-Compliance EMC Testing early and often in product development. The problem is the time and money wasted accomplishing offsite testing! The lead time for testing slows things down as well. The ability to perform testing in your own facility would be great. Many companies have faced this problem over the years. VTT has designed and produced portable testing enclosures for many years. These RF Shielded Enclosures provide the low ambient...

Conductive Metalized Textiles-not just for Shielding!
Conductive Metalized Textiles-not just for Shielding! When conductive textiles were first developed, Shielding was their use. They were used to make sure car radios worked well. RFI and EMI were blocked, eliminating static hissing! They are still used to protect critical systems from RFI/EMI. They are also currently used in many different ways. Conductive Metalized Textiles-not just for Shielding! The medical sector uses conductive textiles as sensors. Human vital signs are detected by sensors and sent to recording devices. The human...

Pre-Compliance EMC Testing-Essential in Product Development!
Pre-Compliance EMC Testing-Essential in Product Development! Save time and money in electronic product development! Electronic products must pass EMC Compliance testing before marketing. It isn't essential during product development, but it makes development smoother! EMC testing helps assure that your product meets necessary standards. The best practice is to test early and often during development. Waiting until the product is nearly finished almost assures failure. Failure necessitates "backtracking" to find the problem that caused failure. The failure point must be...

RF/EMI Shielded Curtains-Privacy and Separation!
RF/EMI Shielded Curtains-Privacy and Separation! In our lives, we use curtains for privacy, separation, and protection. RFI/EMI Shielded Curtains are used in the same way. RF Shielded curtains are made of conductive metalized textiles. These curtains block the passage of RF and EMI waves. One of the major uses of these curtains is in hospital telemetry areas. They effectively isolate the beds in a "shielded room". This assures that the proper information is transferred to the proper recording device. The...

Ideas to Reality-Product Design and Development!
Ideas to Reality-Product Design and Development! Products don't just appear; they evolve from great ideas! The path from idea to final product has many steps. The first step is the idea, the cornerstone of the product. A person conceives a better way to accomplish a task. The challenge is to make the idea become a reality. In many cases, the inventor is only a "dreamer". He has no idea of how to make his "dream" a reality. Help often comes...

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...

RF/EMI Shielding-the Key to EMC!
RF/EMI Shielding-the Key to EMC! Electromagnetic Compatibility Standards must be met prior to marketing devices. The device must perform well in a shared electromagnetic environment. It must not disrupt the performance of other nearby devices. It must not be disrupted by its environmental coworkers. The "potential disruption" is caused by RF/EMI outside of acceptable standards. In the US, the FCC determines these standards. In Canada, Industry Canada determines the standards. Europe requires the "CE" mark that represents compliance. Every country...
