TSU physicists invented new quality evaluation method for space chips

TOMSK, Mar 11 – RIA Tomsk. Scientists of Tomsk State University (TSU) are working on creation of a new quality control method for electronic circuit board, which are used in space vehicles and military equipment, the press-service of the university informed.

It is emphasized that electronic boards are at the core of any electronics – even the simplest cell phones. At the same time in space or in military technology devices must be able to work for a long time under extreme loads, which means that this e32quipment should be thoroughly tested and long-term predictions about its work should be given – for 15 years forward. Thus electronic boards become all more complicated and more tinier.

"The team under the direction of junior researcher of TSU scientific research institute of applied mathematics and mechanics (AMM) Anton Azin develops the concept of finding and identifying hazardous defects in the design of electronic circuit boards. <…> They use for this purpose essentially new approach which consists of combined application of methods of x-ray tomography and acoustic emission", – is told in the message.

According to the press-service, Tomsk scientists suggest to simulate at the first stage the basic operating modes of electronic board as a part of specific equipment. Then, with the help of sound effects, they limit zones of active defects, with the help of X-ray define their parametres and on the basis of this data do the predictions about working capacity of the device.

It is noted that the new method will allow not only to improve quality of devices, but also will reduce term of production of space and military technology. In 2016 the project was supported by the grant of the Russian fund of basic researches.
