New Surface Mount RFI Clips Speed Product Assembly Time

 

A new range of surface mount EMI/RFI shield clips from UK-based interconnect company Harwin help reduce assembly time and simplify rework by eliminating secondary soldering operations. Unlike conventional EMI/RFI shields that must be hand-soldered to the board, these new shield clips are supplied in industry-standard tape-and-reel packaging and can be soldered using standard … [Read more...]

British Scientists Issue Call for Sense in Assessing EMF Risks

 

Eight prominent British scientists have published a paper calling for sense in regard to the supposed health perils of “electromagnetic smog” and have criticized companies that seek to profit by taking advantage of baseless fears. Among the products criticized were tummy wraps for expectant mothers and shielding products such as headgear and bed netting. Physicians were … [Read more...]

Block Shield Subsidiary Receives Contract from Major U.S. Auto Manufacturer

 

UK-based Block Shield PLC has announced that its wholly-owned U.S.subsidiary Wave Zero has won an initial six-month blanket order contract to provide a major U.S. auto maker with EMC solutions. The solutions are designed to reduce the risks of non-compliance and field malfunction while reducing weight—ensuring EMC compliance with IEC Standard 60601-1-2, RoHS, WEEE, FDA, and FCC … [Read more...]

Fabric-Over-Foam Gaskets Target Card/Cage Operations

 

The new DYNASHEAR™ family of fabric-over-foam gaskets from Schlegel Electronic Materials (SEM) has been crafted especially for card/cage applications. A unique D-design helps assure maximum shielding even at low compression. Ultra-soft, open-cell polyurethane foam is utilized to achieve an impressive ratio of comprehension vs. load. The DYNASHEAR design takes into account the … [Read more...]

Robert Yff, age 77, a longtime Norwalk resident, died Sunday October 19, 2008 of injuries sustained from a fall at the summer home he built on Fire Island. Born in Venezuela of Dutch parents on January 22, 1931, he was the son of the late Johannes Yff and Sophia Magdalena Korlaar Yff. Robert was the husband of Mary Margaret "Peggy"Girard Yff. He was pre-deceased by his first … [Read more...]

Initial Safety and Efficacy Data on Allowing MRIs for Pacemaker Patients

 

Initial safety and efficacy data on Medtronics’ investigational implantable device—the ENRhythm MRI™—were presented August 31 at the European Society of Cardiology Conference. An ongoing study hopes to find a solution for patients with pacemakers who also require the diagnostic benefits of an MRI (magnetic resonance imaging) scan. Results presented showed no MRI-related … [Read more...]

Op Amps Feature Integrated EMI Filters

 

The LMV83x Series of operational amplifiers from National Semiconductor has integrated EMI filters that maintain the accuracy of analog systems by reducing the effects of RF (radio frequency) interference. They are reported to have an EMI rejection ratio (EMIRR) of 120 dB. The LMV831 single, the LMV832 dual, and the LMV834 quad op amps feature CMOS inputs, a maximum inset … [Read more...]

FCC to Test for Interference Between Wi-Fi and Cellular Phone Networks

 

The Federal Communications Commissions’ Office of Engineering and Technology has begun running tests in Seattle, WA to determine the extent of spectrum interference between next-generation Wi-Max systems and cellular phone networks. A provision of the FCC’s slated auction of the 2155- to 2180-MHz band is that a winning bidder must set up a free wireless broadband network. … [Read more...]

Kits Include All Needed Antennas for Shielding Effectiveness Testing

 

The AK-285R and the AK-285T from A.H. Systems are antenna kits that include all the antennas required for shielding effectiveness testing. Included are a log periodic antenna, a bi-conical antenna, an active monopole/loop antenna, and a double ridge guide horn antenna.  Each component has a specific storage compartment in the carrying case, thus forestalling possible loss or … [Read more...]

Solving the Galvanic Corrosion Issue in EMI Shielding

 

Tungsten carbide/aluminum composite particles inhibit galvanic corrosion of aluminum. Harry Fuerhaupter, Potters Industries, Inc. ABSTRACT An ongoing issue in the design of reliable EMC shielding is galvanic corrosion of aluminum. How can an aluminum frame be protected from galvanic corrosion if it contacts an EMI gasket containing non-aluminum particles? Chromate conversion … [Read more...]
