Future Remote Sensing Satellites with high resolution electro-optical payloads require multiple detectors to meet mission goals of multiple spectral bands and large swath. High speed detectors are available with limited pixels array length with multiple video ports. Large number of detectors at the focal plane calls for miniaturized camera electronics. Miniaturization requires usage of low power, low weight components and adaption of new packaging techniques like Multi chip module, System-in Package, Systems-on-chip and wafer level packaging etc. These technologies require multiple dice which are not readily available in required high quality levels. Hence, new packaging approach named as vertically stacked packaging (VSP) is developed in-house and demonstrated. This incorporates vertical stacking of PCBs, inter-board interfaces using copper leads, usage of flexi-rigid boards, single external interface connector and vertical passive component mounting. Here, using VSP technology, reduction is achieved in size by about 91% and weight by about 85% as compared to traditional packaging approaches. This paper mainly discusses the VSP development, optimization and integrated test results with 4K TDI detector.
