金刚石/Cu材料在快启动红外探测器中应用的可行性分析

Feasibility Analysis of Application of Diamond/Cu Materials in Quick-start IRFPA

针对当前制冷型红外焦平面阵列(Infrared Focal Plane Array,IRFPA)探测器对制冷启动时间(快速启动)的要求,对影响探测器启动时间的具体因素进行了分析。结果表明,冷台零件的降温速度对探测器的启动时间有一定程度的影响。对当前国内导热材料进行了调研,找到了一种与红外探测器混成芯片相匹配的材料,并对该材料的初步工艺进行了验证。

According to the requirements of the current cooled infrared focal plane array(IRFPA)detector for the cooling start-up time(quick start),the specific factors that affect the start-up time of the detector are analyzed.The results show that the cooling rate of the cold platform parts has a certain degree of influence on the start-up time of the detector.The current domestic thermal conductivity materials are investigated.A material matching the infrared detector hybrid chip is found,and the preliminary process of the material is verified.
