摘要： A fabrication process for coils to be used in high-temperature operations, such as coil for use in electromagnets for thrusters. The fabrication process includes preparing a slurry of castable inorganic composite potting materials in water. A wire, such as a copper wire is coated with the slurry using a coating device. The wet coated wire can then be wound on a filament winding device, in near real-time, to obtain a wet coil. The wet coil can be kept for setting and drying, and thereafter the dried coil can be cured under high temperature and/or pressure.

摘要： An electronic component includes a second insulating layer laminated on a main surface of a first insulating layer in which a circuit pattern is embedded, so that stacking misalignment or step-off of a wiring layer is prevented without impairing electrical characteristics. An electronic component includes a first insulating layer having a main surface; a circuit pattern embedded in the first insulating layer and extending along a plane parallel to the main surface; and a second insulating layer laminated on the main surface. A section of the first insulating layer orthogonal to the main surface is an inverted trapezoid in which a length of a lower side opposite to the main surface is shorter than a length of an upper side on the main surface side.
