Computerised reorganisation of PCB(s) using VDU work station - having raster pattern points set by mouse repositioned automatically

摘要

The coordinates of the actual positions of points on a symbolic PCB on the screen of an interactive workstation with VDU achieved by moving a mouse are stored. Subsequent drill pattern lines are defined in a certain coordinate direction. Actual point coordinates are replaced by those of bounding pattern lines and adjusted according to the half of the space between bounding lines occupied by the actual points. The cursor position is adjusted accordingly. USE/ADVANTAGE - For simplification of computerised reorganisation of PCBs with non-rhythmic line patterns for holes or conductor runs.
