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 weight and flexibility....

Pre-Compliance EMC Testing-Find out Early!
Pre-Compliance EMC Testing-Find out Early! I always like to find out what I'm in for as soon as possible! I always love "practicing" for a test that is coming my way. They help me to sharpen my skills in the areas where I am underprepared. Final EMC Compliance tests must be passed prior to marketing electronic devices. Pre-Compliance EMC Testing is a very practical way to prepare for the Final EMC Compliance test. Testing a product early and often during...

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...

Product Development-use Pre-Compliance Testing!
Product Development-use Pre-Compliance Testing! Product development in the electronics industry is very difficult! EMC Standards must be met depending on product type and its function. When the product is complete, it needs to pass the Final EMC Compliance Testing at a registered facility in order to be marketed. This exam is all-inclusive, touching on the entire device. It's best practice to perform Pre-Compliance testing on the device during development. This stepwise practice eliminates the need for back tracking to find...

RF Shielded Curtain or Enclosure?
This may seem like a difficult question, in some cases the correct answer is BOTH! One of the beautiful things about an RF Shielded Curtain is that it can multitask! An RF Shielded curtain can isolate an area from RF radiation. This comes in handy in repairing or testing an electronic device's performance "in situ" when the "Device Under Testing" (DUT) won't fit into a RF Shielded Enclosure or can't get to one. An RF Shielded Curtain is made out of...

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-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...
