  • Patent number: 12295097
    Abstract: A planar sensor array, like an imaging sensor array, can be mounted to a ceramic circuit board to provide improved mechanical stability and heat dissipation. Embodiments herein provide improvements to such assemblies by providing two or more recesses in the ceramic circuit board opposite the sensor array. Electronic components can be placed in these recesses, reducing the overall size and moment of inertia of the sensor assembly relative to placement on the same side of the ceramic circuit board as the sensor array. Placing the electronics in the two or more recesses allows for simplified mounting of the assembly to heat sinks, flexible circuit boards, or other elements. The two or more recesses are separated by a stiffening cross-brace portion of the ceramic circuit board that enhances the mechanical strength of the ceramic circuit board.
