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...

Your RF Shielded Enclosure-Custom-Made!
Your RF Shielded Enclosure-Custom-Made! Almost every electronic device under production is unique! They all have one thing in common-they must pass EMC Final Compliance Testing prior to marketing them! The EMC Compliance Testing is based on different classes of accepted standards. The standards vary for each class of device. EMC Testing takes place in RF Shielded enclosures with low ambient levels of RF present. During EMC testing, devices are evaluated for the amount of RF radiation that they can perform...

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...

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 should be that...

Pre-Compliance EMC Testing at “Home” Works!
EMC Pre-Compliance Testing at "Home" Works! Everyone knows that every new electronic device has to pass EMC Final Compliance Testing prior to marketing. Final Compliance Testing is available at certified testing centers. Pre-Compliance EMC testing, done at "home" during the developmental process, prepares new devices for EMC Final Compliance testing. Proceeding in this fashion, saves travel time and money, at the same time eliminating potential "failure points". Eliminating "failure points" in development increases the chances of passing EMC Final Compliance...
