Abstract: Provided are methods of forming thermally conductive flexible bonds for use in electronic boards of unmanned spacecrafts and other types of aircraft. Also provided are methods of preparing adhesive materials to form these bonds including methods of preparing treated filler particles. In some aspects, an adhesive material includes filler particles having organofunctional groups, such as boron nitride particles treated in silane. These particles may be combined with a urethane modified epoxy to form the adhesive material. The weight ratio of the particles in the adhesive material may be about 40-60%. The adhesive material may be thermally cured using a temperature of less than 110° C. to prevent damage to bonded electronic components. The cured adhesive may have a thermal conductivity of at least about 2 W/m K measured in vacuum and may have a glass transition temperature if less than −40° C.

Abstract: Provided are an insulating ceramic paste, a ceramic electronic component, and a method for producing the ceramic electronic component that allow prevention of solder shorts between narrow-pitch terminal electrodes and suppression of generation of cracks in an insulator covering a portion of terminal electrodes during a firing step. The ceramic electronic component includes a ceramic multilayer substrate, terminal electrodes formed on a surface of the ceramic multilayer substrate, and an insulating ceramic film formed on the surface of the ceramic multilayer substrate so as to cover a portion of the terminal electrodes. An exposed surface portion (celsian-crystal-rich layer) of the insulating ceramic film has a thermal expansion coefficient that is lower than the thermal expansion coefficient of the ceramic multilayer substrate.
