    Orcad Layout solder mask area Reply

    Does anyone know how to create an area on PCB that will not be covered with solder mask?

    You can create a shape using an obtsacle on solderamask  layer, but it still fills the solder mask inside of it.

    In my experience, the soldermask layer is like a negative layer.  It shows where soldermask won't be.  In other words, it shows where the openings in the soldermask layer are.

    Good Day, R².

    Hi Randy
     
    Thanks for your respond.
     
    This is correct.

    My goal is to create a rectangle area were the solder mask does not exists.

    It does not seems like there is an obstacle that does that.

    Add->Rectangle, then in the Options Tab select an appropriate class/subclass; i.e. Board Geometry/Soldermask_Top, and draw the rectangle.  You'll also need to make sure this class/subclass is part of the soldermask film in your Artwork Control Form.

    Good Day, R².

    First clarify what do you mean by "solder mask". The OBTACLE you draw or the PAINT on the board. It is a clasical use of word confusion.

    I am going to name SOLDER MASK the obtacle you draw in Orcad.

    Suppose you DO NOT want paint on the whole bottom layer (RF board a must), you want only finished metal exposed.

    In this case you have to copy the board outline on the soldermask layer.

    In conclusion, you have to have an obtacle on the SM layer over the area where you do not want paint (or you want only metal exposed).

    I do not think you have classes in Orcad Layout.

    Do you?

    Hi Randy,

    I think he is designing in Orcad Layout, not Allegro.

    This is only true from the logical point of view. I did a new obstacle, square shape, and put it to the SMT (Solder Mask Top) layer. When gerber files produced, solder mask layer shows you this square which is not "filled" inside, just a frame. -( I'm probably looking for some sort of option to fill it in.

    Did you actually did it in Orcad Layout?

    Yes, Orcad Layout.

    Whoops, sorry about the confusion.  I was thinking about Allegro and totally missed the Orcad Layout mentioned in the subject line.

    Good Day, R².

    RE: RE: RE: Orcad Layout solder mask area Reply
    Hello Everyone,

    I was trying to open allegro from cmd.exe by typing allegro, but I get the error below:

    The device is not ready.

    The system cannot find the file user_name.txt

    (echo was unexpected at this time.

    I need this to work so that I can run a .bat file that requires Allegro to be opened in this manner.  Have anyone encountered this problem or know what user_name.txt is?  Please advise if anyone can help

    Thank you,

    Seiji
