Who uses Conductive Metalized Textiles-Everyone!
Who uses Conductive Metalized Textiles-Everyone! Until I came to work at V Technical Textiles, Inc., I didn't know anything about them. Today, I am amazed at the number of ways metalized textiles are involved in our lives. One of the first uses of them made it possible for me to listen to an FM radio in my car! I recall FM radios seemed particularly sensitive to RFI (Radio Frequency Interference) and were not easy to listen to. This due to...

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...

EMC-Achieve it with Proper Shielding!
EMC-Achieve it with Proper Shielding! Electromagnetic Compatibility means that the electronic devices in a shared Electromagnetic Environment are able to perform together, without interfering with each other. The two main concerns are Emissions and Susceptibility. Emissions of RF radiation occur when any electronic device is operating. If the emissions are within the limits of applicable EMC standards, the device is compliant with the standard for emissions. If the RF emissions of the device are above the standard, the device is...

RF Shielded Enclosures-Perfect Testing Environments!
RF Shielded Enclosures-Perfect Testing Environments! You've heard me say that EMC is all about the environment. EMC means all of the electronic devices in a shared electromagnetic environment are able work together smoothly. RF Shielded Enclosures are used in testing electronic devices to assure that the devices can work in a standard environment together while not making that environment toxic for other devices. EMC Testing requires a controlled low ambient electromagnetic environment. The only electromagnetic radiation present...

Resistance Heating-great in Winter!
Resistance Heating-great in Winter! Winter is here! This is the time of the year when Resistance heating is useful in many situations. In the automotive field, resistance heating comes into play in three areas. Heated seats, steering wheels, make us very comfortable, keeping our extremities, backs and posteriors warm. Rear windows and heated mirrors are often cleared of frost and cloudiness with conductive heat, increasing our vision. Resistance heating involves using the resistance of metal to quickly convert electrical energy...

Experience, Research, Dedication, and Commitment!
Experience, Research, Dedication, and Commitment! These are the words that I place at the very end of every blog that I produce for V Technical Textiles, Inc. Those words accurately describe the approach we take in our day-to-day work. We design and manufacture many products for our valued customers. This doesn't mean that VTT's products are made the same way every time. Every time a product is put on the schedule, a full review of the entire...

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. ...

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...
