2023: High palladium and ruthenium resistive paste generation

Holding "Roselectronics" of the State Corporation "Rostec" on December 21, 2023 presented the next generation of resistive paste for the production of chip resistors. As representatives of Roselectronics told TAdviser, it is distinguished by a high content of precious materials, which made it possible to increase the service life of electronic components to 25 years. For comparison, analogues of popular foreign brands last about five years after installation on a board.

The key feature of the new pastes is the high content of palladium and ruthenium, which allows components to maintain stability of characteristics throughout their service life. And the use of silver in the contact areas of the resistors ensures the highest possible level of soldering and the reliability of the contact connection, the holding explained.

The next generation of resistive pastes was created by specialists from the Novosibirsk plant of radio parts "Oxide," which is part of Roselectronics, as part of an initiative development work. At the same plant, mass production of chip resistors was also organized with the support of the Industrial Development Fund (FRP).

"Chip resistors are actively used in most electronic systems, so the market is experiencing a tremendous need for such products and has special requirements for its reliability and durability. Our new development has higher technical characteristics compared to foreign counterparts, but at the same time has a comparable price, "said Lev Nosenko, General Director of NZR" Oxide. "

Chip resistors are used to make a wide range of products: from mobile phones to automotive and industrial electronics.
