摘要： A structure and method for instrumenting a component for monitoring wear in a coating. The method includes depositing a first thin layer of electrically insulating material, depositing a thin electrically conductive layer over the first electrically insulating layer, depositing a second thin layer of electrically insulating material over the electrically conductive layer. An overlying thickness of the coating material is deposited over the second thin layer of electrically insulating material. The thicknesses of the insulating and conducting layers is controlled to be small enough such that the overlying coating surface exposed to mechanical wear retains a desired degree of smoothness without the necessity for a separate planarization step.

摘要： A printed circuit board (PCB 22) capable of withstanding ultra high G forces and ultra high temperature as in a gas turbine (11). The PCB includes a substrate having a plurality of cavities (30A, 36A) formed therein for receiving components of a circuit, and conductors embedded in the PCB for electrically connecting the components together to complete the circuit. Each of the cavities has a wall (36A′) upstream of the G-forces which supports the respective component in direct contact in order to prevent the development of tensile loads in a bonding layer (37A). When the component is an integrated circuit (50), titanium conductors (63) are coupled between exposed ends of the embedded conductors and contact pads on the integrated circuit. A gold paste (51) may be inserted into interstitial gaps between the integrated circuit and the upstream wall.
