چکیده
There is a rapidly growing interest in the development of electronic microsystems that can maintain functionality high temperature environments, particularly power generation and aircraft engines where operating temperatures exceed 500 °C. The current work presents major advancement toward additively printed electronics made for applications. Here, system represented by gold-based electrical structures have been on 3D ceramic substrates. substrate alumina-based with purity level 99.8% was fabricated through photopolymerization digital light processing (DLP). An aerosol jet printing technique deposit an ink stream down to 10 µm utilized fabricate structures. gold printability its adhesion were assessed. Furthermore, microwave dielectric constant loss tangent alumina extracted measurements scattering parameters transmission lines up 750 A conformal broadband antenna successfully tested at 850 showed excellent stability after aging slightly increased 450 °C significantly between It found as increased. This entirely additive manufacturing-based approach components including substrates, interconnects, RF elements

Reconfiguration of Analog Electronics for Extreme Environments
This paper argues in favor of adaptive reconJiguration as a technique to expand the operational envelope of analog electronics for extreme environments (EE). On a reconfigurable device, although component parameters change in EE, as long as devices still operate, albeit degraded, a new circuit design, suitable for new parameter values, may be mapped into the reconJigurable structure to recover ...

This paper argues in favor of adaptive reconfiguration as a technique to expand the operational envelope of analog electronics for extreme environments (EE). In addition to hardening-by-process and hardening-bydesign, "hardening-by-reconfiguration ", when applicable, could be used to mitigate drifts, degradation, or damage on electronic devices (chips) in EE, by using re-configurable devices an...
متن کاملHigh Temperature Electronics Packaging
Materials and processes are being developed for packaging of low and medium power, high temperature electronics (up to 500). Ceramic (Al2O3 and AlN) hermetic packages are being used. Die attach techniques based on patterned Au bumps, Au-Si and off-eutectic Au-Sn have been demonstrated. Au thermosonic wire bonding provides a monometallic interconnect system between the die and the package pads. ...
