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...

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...

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 whether a device...

Wellness Garments-Comfort and Protection!
Wellness Garments-Comfort and Protection! Wellness Garments are enriched with pure silver containing yarn and thread, making the wearer feel comfortable, relaxed, and well. Silver is the most conductive element, both electrically and thermally. The thermal conductivity of the metalized textiles utilizes the body's natural heat and spreads that heat evenly throughout the garment. This property eliminates hot spots and cold spots, making wearer feel very comfortable. The conductivity of Silver increases the blood flow through the body, increasing energy, at...

EMC-It’s all about the Environment!
EMC-It's all about the Environment! It's terrific when people work smoothly together. They focus on the job at hand and accomplish their tasks efficiently. You feel their compatibility in the easy flow of their work! It's the same way with electric components working together in a shared environment. Electronic devices emit electromagnetic interference naturally while working. These natural emissions can negatively affect the overall functioning of the device. EMC Final Compliance Testing is required for all electronic devices before marketing...

RF Shielded Enclosures-Ideal EMC Testing Environments!
RF Shielded Enclosures-Ideal EMC Testing Environments! We all know that all electronic devices have to pass Final EMC Compliance testing before they are marketed. RF Shielded Enclosures provide ideal conditions for performing Pre-Compliance EMC testing. Compliance testing determines whether or not the device is emitting RF and Electromagnetic radiation that will affect the performance of devices in their shared workspace, or if the device is sensitive to other electromagnetic phenomena. RF Shielded Enclosures create a low ambient RF environment as...

Electronic Devices plus Great Shielding-EMC!
Electronic Devices plus Great Shielding-EMC! Electronic devices are great things, making so many tasks easier and more enjoyable for us! Sadly, they also create EMI and RFI emissions naturally. Unfortunately, some of these emissions affect other devices working in their shared electromagnetic environment adversely. Consider the analogy of an office, one employee talks loudly and makes it hard for the other employees to concentrate at their highest level. The talking employee is an "emitter" of EMI/RFI and the other employees...
