    OrCAD 16.5 Extracting Gerber files. Reply

    Hello all,

     

    I've made a double layer pcb and I now have to get the gerber files so they can be send away.

    The things i've seen about gerber files are a bit confusing to me.

    Can some one give me some clear instructions about creating the different layers like TOP, BOTTOM, SILK_TOP ect.

    I can't see YouTube movies because it is blocked here in my company.

     

    Regrards,

     Tom

    Have a look at <your_install_dir\doc\algroman\algroman.pdf but the basics are set the display to look like what you need for your artwork (turn layers on/off to suit) the go to Manufacture Artwork - Film Parameters, select one of the artwork names and use RMB (right mouse button) Add and specify a name, the artwork name produced will match the display.

     The .art file can be read into any Gerber viewer (It is Gerber Data). Look at Manufacture - Artwork - General Parameters tab for the gerber types you can use. Most gerber viewers will read this. Take a look at GC-Prevue or CAM350 or Viewmate.

    If you want to change the file extension type look at Setup - User Preferences - File_management - Versioning and change the ext_artwork from art to gtd

    we are getting error  when creating negative art file,
     
    we need its Image polarity for a negative etching. 
     
    ERROR: aborting film - Layer polarity of layer ETCH/TOP does not
               match film polarity of Negative. DRC may be unreliable,when going to create negative art file.
     
    What is the cause of its?

     You dont really need to generate Negitave artwork for you gerbers. Most board-houses make composities of your gerbers anyway so they can plot the gerbers on film.

    Suggest you put out your artwork layers as positive layers using RS274X Format.

    Was there a particular reason you wanted to create negative film ?

    Thanks Scott
