Water-Based Sodium Silicate System for EMI/RFI Shielding

 

Master Bond, a manufacturer of epoxy adhesives, sealants, coatings, potting and encapsulation compounds, has released MB600S, a water-based sodium silicate formulated for coating applications requiring EMI/RFI shielding. “Tested according to IEEE 299, 2006 methods, MB600S was as effective as the aluminum reference with a range of 95-105 dB, from 100 MHz to 2 GHz. Above 2 GHz, … [Read more...]

New Military Satellite Test Device to Simulate Natural and Man-Made Electromagnetic Effects

 

A new device that simulates high-radiation events will be used to test the durability of the military’s most advanced satellites against extreme space weather at the Arnold Air Force Base in Tennessee beginning this summer. Developed by Welkin Sciences in Colorado Springs, Colo. and the Arnold Engineering Development Complex’s Test Technology Branch, the Military Satellite … [Read more...]

New Adhesive for IC Packaging and EMI/RF Shielding

 

Intertronics, a producer of adhesives, has released Polytec EC 275, a paste-like adhesive, ideal for "IC  packaging, connecting circuits to copper coils (RFIDs or smart cards) and EMI/RF shielding.” “Polytec EC 275 utilizes nickel-free fillers not based on silver flake to create an electrically conductive performance appropriate for die attach, SMD bonding, RFID antennas, and … [Read more...]

EMI Contact Fingers Help Prevent Interference Between Nearby Embedded Systems

 

Würth Elektronik, a provider of EMC components, has announced the WE-SECF series of EMI contact fingers for the prevention of interference between embedded systems or conductive housings installed next to one another. According to the company, the WE-SECF series is made of copper-berylium and is gold-plated, giving the material a very low resistance and the ability to … [Read more...]

Select Fabricators, Inc., a manufacturer of RF/EMI shielding enclosures, pouches and mobile forensics products, has released two patent-pending, non-radiating customizable door closure systems that help to reduce RF/EMI leakage in the company’s RF-shielded portable enclosures and tents. According to the company, the RF/EMI shielding enclosures are constructed with a … [Read more...]

Carbon Nanotubes Less Electromagnetically-Sensitive than Current Systems, May Open Door to Growth of Quantum Computing

 

Physicists at the Technische Universitaet Muenchen (TUM) in Munich, Germany have demonstrated a way for nanotubes to store information in the form of vibrations, opening the door to the possibility of replacing traditional, but still mostly experimental, systems based on electrically charged particles held in an “electromagnetic trap” that require extensive shielding with … [Read more...]

Maine at the Forefront of National EMP Protection Debate

 

Recent legislation introduced in Maine has demonstrated the aggressive stance the state has adopted on a topic Washington remains reluctant to address—defending against the possibility of a natural or man-made electromagnetic pulse capable of disabling the country’s electrical grid system. Introduced by Rep. Andrea Boland, LD-131 was taken up by the Joint Standing Committee on … [Read more...]

French Fashion Label to Debut Electromagnetic Wave-Blocking Menswear

 

A French fashion label has announced the upcoming release of men’s suits reportedly capable of blocking electromagnetic waves produced by cell phones and other portable electronic devices. “This is the first [commercial] use of technological materials in everyday men’s clothing that doesn’t cause discomfort,” Benjamin Anin of Smuggler’s research and development department … [Read more...]

Autocatalytic Nickel over Autocatalytic Copper for Electromagnetic Shielding

 

From the International Standards Organization webstore: “ISO 17334:2008 specifies the requirements for autocatalytic nickel-phosphorus alloy coatings applied over autocatalytic copper coatings to provide electromagnetic interference (EMI) or electrostatic discharge (ESD) protection for parts fabricated from either plastics or metallic materials. ISO 17334:2008 does not apply … [Read more...]
