The idea[]
A type of Soviet calculator IC. The Soviet Ministry of Electronics Industry (KNIIMP) ordered the creation in 1970 of the first Soviet and Europe 4 chip calculator based on large-scale integrated circuits MOS technology which was it's self based on a dynamic (clocked) with integration keys making up to 500 transistors integrated on to a single chip. It was relitvly cheep by Western prices, but painfully expensive for Soviet Unions.
Manufacturing[]
N\A, but probably akin to then Western practices.

Soviet microchips were originally rip-offs of Western types, but they were designing the own types by the 1980s. Armenian types were the leading type in the USSR for speed, power consumption, accuracy and efficiency by time of the Dissolution of the Soviet Union, with those in the Baltic States being close behind.
Casing[]
A metal can with epoxy inside sits over the IC that is on a epoxy pad. The legs are metal and attached to the IC with thin gold wires. Some were fully encased in epoxy resin.
