Free White Paper on Nanocrystalline Coating for Magnetic Shielding

 

In this white paper, Integran discusses a new conformal metal coating process that provides direct magnetic shielding to metal and polymer parts, such as electronic enclosures. This avoids the awkward forming and integration steps with conventional foil and sheet metal materials. The Nanovate™ coating affords design flexibility that can reduce weight, bulk, and boost the … [Read more...]

Nokia N8 Teardown Finds Sharp Design

 

In a teardown of Nokia’s flagship N8 smartphone, repair site iFixit deemed the placement of the phone’s EMI shield a standout feature.After removing the screws and popping off the antenna, which Nokia put near the plastic plates near the top and bottom of the largely aluminum N8, the mid-plane can be removed. “The design of the steel mid-plane is pretty genius,” iFixit wrote. … [Read more...]

EMI-Reducing Differential Oscillator

 

MSC Vertriebs GMBH’s new SiT9002 AI oscillators are designed to use built-in spread spectrum technology to reduce EMI up to 16 dB. The spread spectrum technology also allows passing compliance testing without lengthy delays, expensive board redesign or shielding. The oscillator offers several features that are compliant with PCI-Express and FBDIMM timing standards.Visit MCS to … [Read more...]

Living Life at 2.4GHz

 

In a recent article in Gizmodo discussing why 2.4GHz was chosen for unlicensed wireless items, attention focuses on the frequency of microwave ovens. The article notes that despite heavy shielding, microwave ovens’ powerful emissions could sometimes interfere with neighboring frequencies, so it was decided that they should be given a few megahertz of space in both … [Read more...]
