Metallized Textiles

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.  The RF shielding...
RFI/ EMI Shielding Conductive Textiles

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...

Testing Situations-Prepare for them!

Testing Situations-Prepare for them!  You remember it from school, from the first day of class, you knew that there would be a "Final Test".  The "Final" would determine whether you would move on to the next level, or whether you would have to repeat the test!  Preparation for the final was very important.  A parallel situation to the "Final Test" exists when developing a new electronic product for marketing.  Commencing with development is the first step for the device toward...

Develop and Test your Product with the Best!

Develop and Test your Product with the Best!  V Technical Textiles, Inc. has been involved in electronic product development and testing for years!  Initially, VTT was known for providing excellent RF shielding materials used in electronic devices.  Shielding materials block access of RF interference to electronic devices, allowing them to perform smoothly!  Additionally, they prevent the emission of RF interference from electronic devices.  VTT's Shielding materials are conductive metalized textiles, used in the automotive, aerospace, medical, and military industries.  Engineers...
EMC Standards are Necessary

Standards are necessary for EMC!

Standards are necessary for EMC!  Electronic devices working in a shared electronic environment must be able to perform optimally in that environment.  In order for this to happen, the shared environment must meet certain "standards".  Imagine expecting a human being able to live in an environment without oxygen.  It's NOT going to happen!  Similarly, electronic devices require an environment with limited range of RFI frequency emissions.  RFI above a certain "standard level" will hinder a device's performance.  A "standard limit"...
Shielding RF/EMI

Shielding RF/EMI allows Electronic Teamwork!

Shielding RF/EMI allows Electronic Teamwork!  Electronic components consist of several electronic devices working together toward a common result.  All electronic devices create electromagnetic fields.  Electromagnetic fields can be the source of "noise" that can affect the function of another nearby device or devices in the component.  Noise produces a "toxic effect" on the shared electronic environment of the component, making it function below its capability.  In order for the devices to be "compatible" with each other, there must be standards...
Electronic Vehicles Developmental Growing Pains

Electronic Vehicles- Developmental Growing Pains!

Electronic Vehicles-Developmental Growing Pains!  The benefits of Electronic Vehicles (EVs)are terrific, lower emissions lead the list of benefits.  Despite the benefits, consumers have some areas to be concerned with.  One of the most frequent owner concerns is range per charge.  This anxiety lies in the difficulty of finding a suitable charging station.  Currently, there is no "standard plug" configuration for charging EVs.  Conversely, the Internal Combustion Engine (ICE) is fueled from pumps with a universal nozzle that fits all gas...
2022 EMC + SIPI

Chris Cook is ready for IEEE EMC Symposium + SIPI in Spokane!

Chris Cook is ready for IEEE EMC Symposium + SIPI in Spokane!  Chris will meet with our Northwest sales representative, Dean Shipman, while he's in the neighborhood. Monday evening, before the Symposium begins, Chris will attend a customer appreciation meeting sponsored by our partner, ETS Lindgren.  Tuesday, Chris will meet with our Northwest Sales Representative, Dean Shipman of Syntek.  Chris will spend the rest of the day walking the Symposium.  The IEEE EMC Symposium +SIPI is the major annual meeting...

Shielding Challenges in Electronic Vehicles!

Shielding Challenges in Electric Vehicles!  Low-frequency magnetic fields are an issue in electronic vehicles.  Low-Frequency fields are related to human health and safety.  Specifically, low-frequency magnetic field exposure of the nervous system where the frequency is below 500KHz.  Additionally, some electric control units of an electronic vehicle can be adversely affected by this phenomenon.  Obviously, anything that effects the controls of an EV can decrease the safety of the vehicle.  The low-frequency magnetic fields in an electronic vehicle are largely...
Autonomous Vehicle Testing-VTT's Role!

Autonomous Vehicle Testing-VTT’s Role!

Autonomous Vehicle Testing-VTT's Role!  VTT's prominent role in automotive EMC testing is well known.  Autonomous Vehicles are loaded with complex electronic devices!   All of the electronic systems must work together in a small shared electronic environment.  EMC testing is what VTT has been known for over the years!  VTT's RF Shielded EMC Testing enclosures have provided the perfect environment for EMC Automotive testing for many years! Autonomous Vehicle Testing-VTT's Role!  Autonomous vehicles require reliable and robust computer systems and sensors.  Elaborate...
