JSC "LIT-FONON" from 1964 to 2004 carried out the functions of maintaining the international secretariat of the technical committee No. 49 "Piezoelectric and dielectric devices for stabilization and frequency selection" of the International Electrotechnical Commission (IEC), whose sphere of activity included the issuance of international standards. The history of the society begins in 1937 with the organization of the first piezoquartz laboratory in the USSR, which, developing, successively became TsNILP (Central Research Laboratory of Piezotechnics), NIIPT (Research Institute of Piezotechnics) and Research Institute "Phonon", as the head Research Institute Research and Production Association "Fonon" (NPO "Fonon"), which included: Research Institute "Elpa", Zelenograd, Research Institute "Elto", Dushanbe, factories - "Morion", Leningrad, "Meteorite", Moscow, Meteor, Volzhsky, Kristall, Yuzhno-Uralsk, Impulse, Cherkassy, Almos, Leninabad, and a number of others. In 1992, Research Institute "Fonon" was transformed into OJSC "Fonon", in 1997 - into OJSC "FONON", in 2002 - into OJSC "LIT-FONON", in 2017 - into JSC "LIT-FONON" A feature of the company is the development and manufacture of microminiature, including for surface mounting, quartz oscillators and resonators with high frequency stability in a wide frequency range, which provide stringent requirements for mechanical, climatic and radiation external influences in accordance with modern requirements. Quartz oscillators and resonators manufactured by LIT-FONON JSC have increased reliability: the resonators RK22M , RK46 , RK62M , RK319 and the generator GK56-P have successfully passed the gamma-percent life test at an elevated temperature (+ 85 ° C) for more than 100,000 hours. The increased reliability of our products is ensured by the use of high technologies, starting with wire cutting of quartz sections into plates at a given angle with an accuracy of ± 30 ”and a cut thickness of no more than 0.15 mm; the use of group technology of grinding, polishing and chemical etching of crystalline elements, automatic processing of the chamfer of crystalline elements, automatic sorting of crystalline elements by frequency, automatic adjustment of the frequency of products by applying additional mass to the electrode or by bleeding the electrode thickness, automatic sealing of ceramic bodies of products, sealing of resonator bodies cold welding, using crystals of integrated microcircuits with welding of their leads with ultrasound and thermocompression welding on thin-film boards, The production of quartz oscillators and a resonator in a ceramic case with overall dimensions, respectively, (7.1x5.1x1.6) and (7.1x5.1x1.15) mm for surface mounting, including one-time programmed crystal oscillators with additional functions, has been mastered. Products in ceramic SMD cases are being transferred to automatic assembly, which will lead to improved quality and increased reliability. Currently, the development of a quartz oscillator with digital temperature compensation in a ceramic case for surface mounting and a quartz resonator in a ceramic case with overall dimensions (5x3.2x0.8) mm for surface mounting is underway.
