TSAMTO, October 7. The holding company "Roselectronics" of Rostec State Corporation has developed a technology for manufacturing nanofolgs for connecting electronic components.
The new material has significant advantages over traditional methods, allowing soldering at room temperature in a fraction of a second.
Nanofolga is used in the connection of electronic components as a controlled, high-speed and area-limited source of high temperature. The material is laid between two elements to be soldered, and a point energy pulse is applied to its edge, for example, a spark from a power source or a spot of a laser beam. As a result, the foil flares up – a chemical reaction occurs, during which heat is released, the adjacent layers of solder melt 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 microns to 60 microns, the gorenje temperature of the material reaches 1500 degrees. C, the propagation velocity of the combustion front is 2-5 m/s. Gorenje
The energy reaction foil with the effect of self-propagating high-temperature synthesis provides high joint strength and allows you to speed up soldering several times without overheating the entire assembly. At the same time, oxygen is not required for the combustion of the nanofolga – it ignites in vacuum and in water. Gorenje
The manufacturing technology of the material is an initiative development of the Omsk Research Institute of Instrument Engineering (part of Roselectronics). The company has established pilot production of nanofolga, deliveries of trial batches have begun.
"The reaction nanofolga can be used not only for reliable soldering of electronic components, especially those sensitive to the junction temperature. The new material is capable of performing the function of an electric igniter and activating various pyrotechnic charges during blasting operations in the mining industry. Foil can also be used for the rapid thermal destruction of digital media," said Vladimir Berezovsky, General Director of the Omsk Research Institute of Instrument Engineering.
The message is posted in open access on the website of the holding "Roselectronics".
