2021: Development of nanofolga manufacturing technology
Roselectronika Holding of Rostec State Corporation on October 6, 2021 announced that it had developed a technology for the manufacture of nanofolga for connecting electronic components. This material has significant advantages over conventional methods, allowing soldering at room temperature in fractions of a second.
Nanofolg is used in connection of electronic components as a controlled, fast-acting and region-limited source of high temperature. The material is laid between two elements to be soldered, and a point energy pulse, for example, a spark from a power source or a spot of a laser beam, is supplied to its edge. As a result, the foil bursts - a chemical reaction occurs in which heat is released, adjacent layers of solder are melted and the components are joined together.
The material is made of several hundred or thousands of microscopic layers of aluminum and nickel. The nanofolga has a thickness of 40 μm to 60 μm, the combustion temperature of the material reaches 1500 ° C, and the propagation rate of the combustion front is 2-5 m/s.
Energy reaction foil with the effect of self-propagating high-temperature synthesis provides high strength of the joint and allows to accelerate soldering several times without overheating the entire assembly. At the same time, no oxygen is required for burning the nanofolga - it ignites in vacuum and in water.
Material manufacturing technology is an initiative development of the Omsk Research Institute of Instrument Engineering (part of Roselectronics). The company has established experimental production of nanofolga, deliveries of trial batches have begun.
{{quote 'The reaction nanofolg can be used not only for reliable soldering of electronic components, especially those sensitive to the temperature of the compound. The material is capable of performing the function of an electric igniter and driving various pyrotechnic charges during blasting operations in the mining industry. Foil can also be used for the prompt thermal destruction of digital media, "said Vladimir Berezovsky, general director of the Omsk Research Institute of Instrument Engineering. }}
