ESA Coordinated final presentation days
Monday, November 21, 2016 - 8:00 am / Tuesday, November 22, 2016 - 5:00 pm CET
From 21th to 22th November, we participate in European Space Agency Coordinated final presentation days, at the Poster Exhibition where Alter Technology will be presenting the poster ” Silicon Capacitors Development and Space Pre-Evaluation”
It is believed that the recent improvement in silicon capacitor technology might provide very interesting advantages such as stable capacitance value over the operating temperature range (up to 200C-250C) or small dimensions. In addition, these new types of silicon capacitors might be used in different kind of application (DC/DC converter, power decoupling, RF application, etc.) with quite low voltage.
Silicon capacitor might replace advantageously, due to relative small height, Ceramic capacitor type I (low capacitance value), and even ceramic capacitors type II (low voltage application, i.e. close to Integrated circuit). GaN application which requires high temperature components would also benefit a high temperature (200C-250C) silicon capacitor range. However, relevant data demonstrating the high reliability, claimed by Silicon capacitor manufacturers shall be provided to confirm parts suitability for space application.
Alter Technology Strategy on Extreme Temperatures
New space missions include more extreme requirements of storage and operational temperatures and vacuum conditions exceeding standard -55ºC / +125ºC conditions Miniaturization implies increase higher power dissipation and hence max junction and PCB temperatures.
Alter Technology Activities
• Parts reliability assessment to ensure mission performance
• Characterization of existing technologies under such extreme temperature conditions
• Understanding of failure mechanism
• Development of specific NEW parts for very extreme application
• Assessment on new packages and assembly methods
Background to the ESA Coordinated Final Presentation Days
Technology needs to be developed, qualified and applied for it to be considered as a success. One of the primary objectives of Directorate of Technical and Quality Management is developing advanced technologies, at the right cost and at the right time, for use on a variety of space missions.
The diffusion and utilisation of technology achievements is essential if the Directorate of Technical and Quality Management wants to keep its role as the ESA innovation engine.
The CFPDs are an event for European Industry and ESA technical experts to showcase their work in developing advanced technology for Space missions. It will consist of oral and poster presentations delivered by European industry, Academia and ESA technical experts highlighting the recently completed technology contracts and the achievements made within the ESA technology programme.
It will also be an opportunity for attendees to form networks and to understand the latest technologies being developed within the different ESA competence domains.
