Aircraft, Satellites Could Use Nanotubes for EMI Shielding

 

Aerospace and aircraft companies as well as the military have been challenged to find ways of effectively shielding sensitive electronic equipment, such as radar and radios from electromagnetic interference without adding a lot of weight to aircraft and satellites (the more massive they are, the more fuel they need to stay in the air or achieve orbit, respectively). Whereas EMI … [Read more...]

CBS Design Guide Released

 

Leader Tech announces the release of a new board-level shielding catalog and engineers' design guide. This EMI shielding brochure contains detailed information on standard, modified standard and custom CBS products. A quick-glance product comparison chart as well as cover retention data and shielding performance is published for each CBS series. A complete section of the … [Read more...]

Partnership Yields Technology Solutions Including EMI Shielding

 

The electronic contract manufacturer, Sunburst Electronics of Erie, Pa., reports that Composiflex, a global supplier of composite products, has selected Sunburst as its strategic partner to offer technology/service solutions to the aerospace and military electronics sectors. Recently, Composiflex has engaged on several projects to produce light-weight enclosures and racks for … [Read more...]

University Picks Building Site Because of Low EMI

 

University of Washington leaders recently broke ground on a molecular engineering building, the location of which was chosen partly because the natural vibration and electromagnetic interference are low at that site. Researchers will be making very sensitive measurements and any movement can interfere with the accuracy. The foundation will incorporate an extra-thick concrete … [Read more...]

Shielded Window Material Takes New Approach

 

Chomerics Europe, a division of Parker Hannifin, has introduced Winshield C, a shielded window display material. Winshield C is a cast monomer material that combines good physical properties with electromagnetic shielding performance and optical clarity. Applications include display filtering in test equipment, medical instrumentation, public information displays and military … [Read more...]

Nanotube Separation Wins Company New Contract

 

Bio Nano Consulting has signed its largest contract to date with an unnamed chemical company to develop a consistent system for the separation of single-walled carbon nanotubes based on their electrical properties. The work will develop the processes to a stage where the client can license and further commercialize the technology. Possible applications for metallic nanotubes … [Read more...]

EM Coating for Low Frequency Magnetic Shielding

 

Integran Technologies’ Nanovate EM coating for low frequency magnetic shielding achieves similar performance to specialty discrete magnetic shielding foils, but uses a process that allows a nanocrystalline metal to be applied directly to metal, polymer and composite substrates. The process flexibility enables applications where part size or complexity makes the use of formed … [Read more...]

New Book Focuses on EMI Shielding

 

A new book published recently by an EMI materials engineer focuses on the role that EMI shielding plays in EMC (Electromagnetic Compliance) design and reviews EMI shielding with emphasis on materials and designs across many industry applications. “Advanced Materials and Design for Electromagnetic Interference Shielding,” written by Dr. Xingcun Colin Tong, PhD, of Laird … [Read more...]

New Material for Low-Frequency Magnetic Shielding

 

MuFerro™ 6800 from Holland Shielding Systems B.V. is a new material for shielding the low frequency magnetic fields found in transformer rooms, power plants, and bus-bar systems. Although most magnetic fields are typically in the 50- to 60-Hz range, MuFerro provides magnetic shielding in the frequency ranges from 10 Hz to 100 kHz. This material can provide a field-strength … [Read more...]

Enclosures Cast in Lightweight Magnesium Alloy

 

Teko Enclosure Solutions’ latest hand-held enclosures are die-cast in ultra-lightweight magnesium alloy with absolute strength and high EMI/RFI shielding properties. The enclosures are sealed to IP 67 (NEMA 4X) protection class, include side profiles with soft-touch surface, have a top recess for membrane keypad or label and include three types of battery compartments and … [Read more...]
