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...

SCIF Construction-are Standards Meetable?
SCIF Construction-are Standards Meetable? Sensitive Compartmented Information Facilities (SCIFs) must be built to very strict standards! SCIF security requirements and construction specs are based on many factors. Included in the list are facility purpose, surveillance risk, and physical location of the SCIF. Sensitive information exchanges, sound damping, and Personnel security are also important parts of the equation. The final assessment will be made by Accrediting Officer (AO) and Site Security Manager (SSM), determining technical measures for each SCIF application. The...

RF Shielded Clothing-Comfort and Protection!
RF Shielded Clothing-Comfort and Protection! RF Shielded clothing protects us from radio frequency radiation. The electronic devices of today emit and receive radio frequency signals. Obviously, the number of devices in today's connected world is growing daily, filling the air around us with RF waves. While no true connection has been established between Radio Frequency (RF) waves and health issues, many people are concerned about them. People have electrochemical processes that keep the body functioning normally. Electrical devices require RF...

RF Shielding Curtains-Separation and Isolation!
RF Shielding Curtains-Separation and Isolation! RF Shielding Curtains are relocatable shields designed for isolating or separating areas from RF waves. Curtains can be made to the customer's specification of size, Shielding Effectiveness, and suspension method. The conductive metalized textiles and number of layers used in their manufacture determine the RF shielding properties of the curtain. RF Shielding Curtains can even be made to withstand weather, UV, and rough treatment with a "ruggedized finish"! RF Isolation is important in many areas and...

Rugged Conditions Require Ruggedized Textiles!
Rugged Conditions Require Ruggedized Textiles! RF Shielded Enclosures are usually located indoors, protecting them from the elements. The thin conductive textiles used to manufacture enclosures can't stand up well unprotected in extreme conditions. Wind, rain, and ocean spray can damage or destroy the enclosures very quickly. The military and law enforcement often need command centers for their activities to be portable and able to stand up to tough conditions. Lives are at stake in these harsh environments as well as...

Conductive Textiles-What are their uses?
Conductive Textiles-What are their uses? Conductive Textiles are often used in "technical applications". VTT markets conductive textiles, meaning an electrical current can pass through them. That current can be a "message", "data", or part of a circuit. Metals are great electrical conductors. The most conductive metal is Silver, followed by Copper and Gold. Gold is rarely used in conductive textiles due to its cost. VTT's conductive textiles are primarily plated or coated with Silver, Copper, Nickel, and Tin. Other specialty...
