Vibration tests are important to check the reliability of the components/assemblies. These tests can be a headache and suppose a great cost if the design of the device and the fixing tool are not properly done. Simulation tools are the key to anticipate the problems reducing costs and lead times and doEEEt gives you access, in just one site, to components and specifications from different systems and space agencies (more…)

by Tom Adams, consultant for Nordson SONOSCAN Inc. High-voltage multi-layer ceramic chip capacitors (MLCCs) can experience field failures that are instantaneous and catastrophic. The initiator of the failure very often is an air gap between an electrode layer and a dielectric layer, or within a dielectric layer. The gap may have an X-Y area of any size and may be relatively thick or as thin as a fraction of a micron. (more…)

In order to ensure the proper system operation under such conditions, High-Rel EEE parts have to be submitted to thorough vibration test before their implementation in different areas. These tests must be carried out according to different specifications depending on the application areas. (more…)

The Skeleton SpaceCap product development started in 2011 as part of an ESA commissioned activity to produce a capacitor based on Skeleton’s proprietary Carbide Derived Carbon material. The resulting SpaceCap product is a 100F capacitor with a very high power density of 92 kW/L. The product is now in a qualification phase concerning electrical and mechanical aspects. Radiation performance will be evaluated and qualified in potential follow up activities.
The SpaceCap product presentation will focus on product specifications, results of qualification tests conducted up to date and the equivalent capacitor model to showcase the variation in capacitance (C) and internal resistance (ESR) at different application times (from 1 microsecond to 10 seconds at various temperatures).
One of the main SpaceCap design drivers is to reach 18 years of lifetime at 20 °C at an operating voltage of 2.5 V (derated from 2.85V nominal).
Theme of the presentation will focus on comparative test results (performed by EGGO Space s.r.o) of large format supercapacitors from Skeleton Technologies and well-known competitors. All supercapacitor manufacturers use different measurement techniques making datasheet-based comparison incomparable. The test results presented have been performed according to IEC 62391 standard methods and thus provide high quality results with 10 units tested of each product.
In the tests Skeleton Technologies’ COTS supercapacitors have shown exemplary power performance due to considerably lower ESR in comparison to competing products. The ESR of the best competing product was found to be twice as high with many competitor products having an ESR nearly three times as high.

Modern manufacturing techniques depend on 3D measurement data combined with CAD/CAM techniques for quality control of high-precision components or mass production. Typically, contact measurement has been widely utilized by the industry. However, for complex and small 3D structures, the application of contact measurement is cumbersome or sometimes impossible. Therefore, non-contact measurement has gradually received much attention from researchers and industry.
