In modern conditions in the Russian Federation the equipment of spacecraft with a highly reliable electronic components is possible only through testing technical centers which act as a link between manufacturers of electronic components and their consumers. Given the lack of specialized production of electronic components of the «Space» category in our country, this is the only alternative way. Testing technical centers carry out the formation of batches of electronics for space applications by conducting additional tests of electronic components for general industrial use allowing the rejection of elements containing defects that can manifest themselves during long-term operation in outer space. A modern spacecraft contains about 100–200 thousand electronic components. Taking into account the fact that the on-board equipment of the spacecraft during its operation cannot be repaired, it is obvious that extremely high reliability requirements are imposed on the electronic components of space applications. In this regard the improvement of the methodology for increasing the reliability of the electronic components of space applications is of paramount importance for the further development of the space industry. This article outlines an approach to improving the technology of additional tests in testing technical centers, based on the use of the concepts of homogeneity of the tested batch of electronic components which makes it possible to meaningfully generate samples for destructive physical analysis and radiation resistance tests, as well as to additionally identify emission elements that are potentially unreliable elements.

In this paper we give a brief historical background of the stages of work carried out by “ITC – NPO PM” JSC aimed at ensuring the long-term operation of electronic components for space applications. It is shown that the creation of specialized testing facilities is the optimal approach to make batches of electronic components of the Space quality level. We propose a further scenario to improve reliability of electronic components for space applications, involving the joint work of specialized testing facilities and manufacturing plants to make special batches of devices.

Temperature Range

Ceramic column grid array packages have been increasing in use based on their advantages such as high interconnect density, very good thermal and electrical performance, compatibility with standard surface-mount packaging assembly processes, and so on. CCGA packages are used in space applications such as in logic and microprocessor functions, telecommunications, flight avionics, and payload electronics. As these packages tend to have less solder joint strain relief than leaded packages, the reliability of CCGA packages is very important for short-term and long-term space missions. CCGA interconnect electronic package printed wiring boards (PWBs) of polyimide have been assembled, inspected nondestructively, and subsequently subjected to extreme temperature thermal cycling to assess the reliability for future deep space, short- and long-term, extreme temperature missions. In this investigation, the employed temperature range covers from −185°C to +125°C extreme thermal environments. The test hardware consists of two CCGA717 packages with each package divided into four daisy-chained sections, for a total of eight daisy chains to be monitored. The CCGA717 package is 33 mm × 33 mm with a 27 × 27 array of 80%/20% Pb/Sn columns on a 1.27 mm pitch. The resistance of daisy-chained, CCGA interconnects was continuously monitored as a function of thermal cycling. Electrical resistance measurements as a function of thermal cycling are reported and the tests to date have shown significant change in daisy chain resistance as a function of thermal cycling. The change in interconnect resistance becomes more noticeable as the number of thermal cycles increases. This paper will describe the experimental test results of CCGA testing under extreme temperatures. Standard Weibull analysis tools were used to extract the Weibull parameters to understand the CCGA failures. Optical inspection results clearly indicate that the solder joints of columns with the board and the ceramic package have failed as a function of thermal cycling. The first failure was observed at the 137th thermal cycle and 63.2% failures of daisy chains have occurred by about 664 thermal cycles. The shape parameter extracted from the Weibull plot was about 1.47, which indicates the failures were related to failures that occurred during the flat region or useful life region of the standard bathtub curve. Based on this experimental test data, one can use the CCGAs for the temperature range studied for ∼100 thermal cycles (ΔT = 310°C, 5°C/minute, and 15 min dwell) with a high degree of confidence for high reliability space and other applications.

The paper dwells upon the security and long-term sustainability of space activities and introduces the main guidelines, approved by the UN General Assembly, as well as the guidelines, which did not receive consensus approval in the UN Committee on the Peaceful Uses of Outer Space. The challenges of the long-term sustainability of space activities for achieving the goals, objectives, and means of developing world cosmonautics and maintaining the status of the Russian Federation as a world space power are reflected. The study focuses on the problems and challenges associated with the man-made debris of near-Earth space, the delimitation of air and outer space, the need to organize space traffic control, which is inextricably linked with the deployment of multi-satellite orbital constellations. The issues of counteracting the asteroid-cometary hazard are touched upon. The research findings given in the paper should help representatives of the Russian space industry understand the problems, challenges, and essence of the long-term sustainability of space activities in conjunction with issues of ensuring its security.

AbstractSilver-glass die attach adhesives provide a cost effective means of producing high reliability parts which can withstand the environmental testing required of electronic components. One step processing of these adhesives provides the additional advantages of increased throughput and processing flexibility compared to eutectically bonded assemblies.This paper describes the performance of a one step silver-glass die attach adhesive processed under various time and temperature conditions. The effect of peak firing temperature and dwell time on the ultimate tensile strength of the adhesive will be discussed. Tensile data from parts subjected to thermal shock, thermal cycle and high temperature aging will be presented as an indication of the material's long term reliability.

This work describes the design of a phosphate analyser that utilises a microfluidic lab-on-a-chip. The analyser contains all the required chemical storage, pumping and electronic components to carry out a complete phosphate assay. The system is self-calibrating and self-cleaning, thus capable of long-term operation. This was proven by a bench top calibration of the analyser using standard solutions and also by comparing the analyser's performance to a commercially available phosphate monitor installed at a waste water treatment plant. The output of the microfluidic lab-on-a-chip analyser was shown to have sensitivity and linear range equivalent to the commercially available monitor and also the ability to operate over an extended period of time.

The AD WME items represent sophisticated technical systems (STS) designed for a long-term operation. Upon termination of the specified operational lifetime, the AD WME pieces have a competitive level of performance specification and are potentially suitable for further intended use (including possible modernisation) if judge by their functional capabilities. In order to extend operational lifetime and restore service life, the AD WME overhaul is envisaged. Overhaul was previously performed at specialised military maintenance shops. Due to reformation or liquidation of military maintenance shops, a necessity to create specialised fixed-site maintenance centres emerged. This article considers basic solutions related to creation of the advanced adaptable fixed-site maintenance centres designed to perform overhaul of the AD WME pieces which are in operational service of the Russian Aerospace Forces or planned to be accepted for operational service in future. Innovative solutions related to creation of the adaptable fixed-site maintenance centres are protected with the patents of the Russian Federation.
