Moderately Soft EMI Gasketing Approved for Spaceflight and Military Applications
The GORE-SHIELD® GS2100 EMI gasket is a conductive, adhesive-backed EMI gasketing material that is moderately soft and is approved for spaceflight and military applications. This gasketing can be supplied in die-cut panel forms or in slit width rolls. Slit width material is particularly well suited to manual, "peel-and-stick" gasketing applications. GS2100 consists of a … [Read more...]
EMI Causes Washington, DC Metro Trains to Switch to Manual Operation of Doors
The Washington Metropolitan Area Transit Authority has announced that for the immediate future the opening of all doors on its trains will be controlled by train operators. On rare occasions, doors have opened on the wrong side of the car as the train comes to a stop at a station. This problem has occurred as Metro officials have been working to upgrade power substations and … [Read more...]
Spread Spectrum IC Reduces EMI in USB Applications
A USB 2.0 Peak EMI Reduction IC from PulseCore Semiconductor uses spread spectrum technology to achieve compliance in USB applications. The PCS3P73U00A is based on patent-pending technology and is said to simplify EMI reduction while reducing or eliminating the need for expensive metal shielding, ferrite beads, conductive paint, or filtering networks. Spread spectrum clocking … [Read more...]

Solving the Galvanic Corrosion Issue in EMI Shielding
Tungsten carbide/aluminum composite particles inhibit galvanic corrosion of aluminum. An on-going 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 coatings have long been used to reduce the corrosion … [Read more...]
