Automated Coordinatograph for Manufacture of Microstrip Circuits

In this technique metallized substrate is fixed to the stage in coordinatograph and an elastic varnish covers its face. The coordinatograph is implemented as a desktop apparatus whose operation is controlled by LtATMELGt microcontroller connected to IBM PC through the interface of RS232C standard. The pattern of designed microstrip circuit is loaded in a form of coordinates to PC either from the keyboard or as a file. The software allows editing the pattern. The cutter rotates in order to the blade being directed in the cutting direction. The coordinatograph has working field of 48times60 mm
