Abstract

A TDICCD series control system for a spacecraft based on microsystem packaging comprises a ceramic pin array tube shell, a ceramic substrate, a tube core chip, a multi-layer ceramic dielectric capacitor, a metalized cover plate and a thick film resistor, a plurality of passive and active devices with different functions are packaged in one shell to become a single standard packaging product with multiple functions, and the single standard packaging product has multiple functions. According to the invention, the device has the functions of a system or a subsystem, employs an unpackaged die chip to replace a packaged device, carries out the integration through a ceramic substrate with a smaller size, and can carry out the series control of a multispectral band.

Description

technical field [0001] The invention relates to a TDICCD series control system for spacecraft based on microsystem packaging, and belongs to the field of microelectronic technology for aerospace optical remote sensors. Background technique [0002] In the field of space remote sensing, time-delay integration charge-coupled device TDICCD has been widely used because of its outstanding imaging ability and high sensitivity. With the continuous development of remote sensing technology, the functional requirements of the TDICCD data processing circuit are becoming more and more complex, and the requirements for volume, weight and cost are getting smaller and smaller. On the one hand, limited by the volume and weight of the circuit, the use of traditional PCB boards has gradually failed to meet the current circuit scale requirements. On the other hand, the cost of circuits composed of a large number of chips has gradually failed to meet market demand. Therefore, on the premise of...
