Overview

Solnechnogorsk Electro-Mechanical Plant (Russian: АО «Солнечногорский электромеханический завод», abbreviated АО «СЭМЗ») is a Russian electronics and defense-industry manufacturing facility based in Solnechnogorsk, Moscow Oblast. According to its official website, the enterprise was founded in 1974 and traces its origin to the electro-mechanical plant attached to the Scientific Research Institute of Microdevices, which was commissioned on 10 April 1974 by order No. 182 of the USSR Minister of the Electronic Industry dated 5 April 1974. The company describes itself as the successor to that plant. The plant's core modern output is radio-electronic apparatus and special-purpose equipment. Its stated product lines include satellite communication stations, the microelectronic aerological radar «МАРЛ-А», and complexes of technical communication means, along with other equipment. The company states that since 2006 it has held one of the leading positions among producers of radio-electronic apparatus and special-purpose equipment, and that it is the only manufacturer in Russia and the CIS countries of the «МАРЛ-А» complexes operating within the Roshydromet network, including at polar stations. Beyond finished systems, SEMZ presents itself as a contract manufacturing and engineering partner. Its service portfolio covers assembly and adjustment of boards and products, prototyping of single units followed by serial production, mechanical processing of parts, tooling design and manufacture, and the production of parts from plastics, rubber and other materials. Its production areas include blank preparation, universal machine tools, CNC machines, mechanical, foundry, erosion, assembly, painting, galvanic and heat-treatment sections, which the company says allow it to perform almost all operations on metal and other hard materials. Historically the plant produced a broad range of electronic technology. Its official history notes satellite communication stations as well as consumer products such as the radio-controlled toys «Луноход» (exported as «Планетоход») and the early-1980s toy «Ну погоди». From the mid-1980s to the early 1990s it manufactured «Электроника МС 05.17» personal computers used to equip secondary and higher educational institutions of the USSR. In the 1990s it expanded into consumer goods and civil-industry products, including remote controls for televisions from the Alexandrov Television Plant, wall-mounted telephone handsets, and instruments for monitoring and protecting main pipelines from corrosion. In the 2000s it increased capacity through the acquisition of modern machine-tool, assembly and metrology equipment and began producing the «МАРЛ-А» microelectronic aerological radar. The company operates as a joint-stock company (акционерное общество). Its official website is semzz.ru. It serves partners in Russia and, by its own account, the CIS countries, positioning itself around quality, reliability and flexible cooperation conditions for customers.

History

The Solnechnogorsk Electro-Mechanical Plant was established within the Soviet electronics industry. Its official history states that it is the successor to the electro-mechanical plant attached to the Scientific Research Institute of Microdevices, which was put into operation on 10 April 1974 by order No. 182 of the USSR Minister of the Electronic Industry dated 5 April 1974. The company gives 1974 as its founding year. In its early decades the plant produced a wide class of electronic technology. Its own account lists satellite communication stations among its products, as well as consumer electronics: the radio-controlled toys «Луноход» (exported as «Планетоход») and the toy «Ну погоди», which was popular in the early 1980s. From the mid-1980s to the early 1990s the plant manufactured «Электроника МС 05.17» personal computers, which were supplied to secondary and higher educational institutions of the USSR. The 1990s were a period of diversification. The enterprise expanded its product list by mastering serial production of consumer goods and by producing items for civil branches of industry. These included remote controls for domestic televisions made by the Alexandrov Television Plant, wall-mounted telephone handsets, and instruments and devices for monitoring and protecting main pipelines against corrosion. In the 2000s the plant increased its capacity by acquiring modern machine-tool, assembly and metrology equipment. During this period SEMZ began producing the «МАРЛ-А» microelectronic aerological radar. The company states that it remains the only producer in Russia and the CIS countries of «МАРЛ-А» complexes operating in the Roshydromet network, including at polar stations. It also states that since 2006 it has occupied one of the leading positions among manufacturers of radio-electronic apparatus and special-purpose equipment. Today the enterprise operates as a joint-stock company and combines finished-system production with contract manufacturing services. Its production base includes blank-preparation, universal machine-tool, CNC, mechanical, foundry, erosion, assembly, painting, galvanic and heat-treatment sections, enabling it to carry out almost all operations on metal and other hard materials. It also designs and manufactures tooling and produces parts from plastics, rubber and other materials, and it offers prototyping followed by serial production.
