Description

Technical Field

[0001] The invention relates to the technical field of space optical remote sensing, and in particular to a coupled self-heating detector splicing module component, a focal plane component and an assembly method. Background Art

[0002] The focal plane assembly is an important component of the space optical remote sensor. With the increasing requirements for the width of space remote sensing cameras, the unit, single line array, and short line array of single-chip detectors can no longer meet the requirements of the line array length required for the focal plane. Most of the focal planes of wide-width space cameras are obtained by splicing detectors.

[0003] At present, there are two main forms of detector splicing. One is to fix the detector assembly on the substrate first, and then splice the detector by adjusting the position of the detector in the X, Y, and Z directions; the other is to encapsulate a single detector in an independent module, and then assemble the independent module with the substrate and then splice it; for the first form of focal plane detector splicing, after the detector splicing is completed, the detector rear-end control circuit board will be transferred to the focal plane substrate through the supporting structure. In this assembly form, on the one hand, the detector assembly itself is contacted and connected with the focal plane substrate, and on the other hand, the detector rear-end pins are connected to the circuit board and transferred to the substrate through the supporting structure; this highly integrated integrated focal plane electrical box structure, in Stress concentration is likely to occur during the production implementation process, affecting the stitching accuracy and imaging effect of the focal plane; the second structural form is more flexible. If a detector or electronic component has an abnormality, it is convenient to replace it separately, avoiding the impact on the structure of other components. However, the existing modular focal plane form, although it has the advantages of replaceability and flexible operation, but because the modular detector components are installed independently, each module is connected to the substrate only through the installation interface, and there is no other heat transfer contact with the substrate. If additional thermal control is not implemented, the heat cannot be discharged in time, and the thermal conductivity is insufficient; the temperature of the module components increases, the dark current increases, affecting the imaging level of the detector, and the focal plane structure is prone to thermal stress and thermal deformation.
