The foundation of the Institute for the Production of Radio Sets and Roentgen Machines, "RR Ni ", in 1948, marks the beginning of electronic industry in Nis.
Production of printed circuts boards began in Serbia in 1964 in the ELECTRONIC INDUSTRY-Niš for our own needs, such as television, radio, and telephones. As a result of continuous improvements in our production line, we made the decision to build a new factory. "Ei-Štampana Kola" became a seperate factory in 1978. Soon after, we expanded our market outside of ex Yugoslavia into other parts of Europe and North America. We have been producing multilayer boards since 1986.
