In consideration of an increased interest in multi-layered printed circuits, more and more often designed in higher construction classes with finer patterns and moreover in consideration of an increase of quality of supplied products, the company PragoBoard decided to invest into a new laser raster photoplotter RP 208-NT from the Swiss company First EIE SA and thus to substitute the current photoplotter Mivatec. The developing device Multiline Classic 55 is from the company Glunz & Jensen.
