EPS, an Elma Company, offers shielded
cabinets that have been tested to MIL-STD-461D specifications for EMC. Based on
Optima's M-series, the shielded cabinets feature a rugged steel or aluminum
frame. EMC features include shielded door handles, wrap-foam gasketing
around the door with conductive adhesives, EMI filters, copper gasket fingers
and steel-mesh gasket strips. All of Optima's M-series cabinets also
feature reinforced corner members, cross-bracing and stiffeners to handle
rugged applications. The M-series has also passed MIL-STD-901D and MIL-STD-810F
for shock and vibration.
Optima can also provide creative EMC
solutions for advanced shielding requirements. Incorporating tin-plating
or other conductive metal surfaces with superior electrical continuity
properties can help reduce offending radiated emissions. Using
cost-effective materials, a minimum electric field attenuation of 60 DB of
shielding effectiveness from 100 KHZ to 1 GHZ decreasing to a minimum of 46 DB
at 10 GHZ can be achieved.
A range of
accessories, colors and custom options are available for Optima's cabinets. The
company also offers transit rack cases, command consoles and desks for rugged
Researchers at Lawrence Livermore National Laboratory have published two physics-based models for the selective laser melting (SLM) metals additive manufacturing process, so engineers can understand how it works at the powder and scales, and develop better parts with less trial and error.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
