Create negative artwork or pdf?

cemmanuel

Hello, I am new using OrCad 17.4 and I want to manufacture some pc boards by using the dry film method, thus I need a negative image of my desgin, I show an image of what I want, what I get and what I designed:

The desired result is from windows paint - "invert color".

I go to Export -> PDF... and check Filled pads, Filled shapes, Filter drawing origin, Filter header/footer and Output PDF in black and white mode. In addition, I have tried many different combinations on Film Creation... but I do not get what I need.

I know that my problem can be easly solved on an image/pdf editor like photoshop or inkscape, but I really think this should be a simple problem and I would not like to use multiple softwares.

Thanks in advance and I hope the best.

  • Hi

    The PCB Editor does not have the ability to do what you want. You basically need a Gerber Editor to do this. A very good tool that is popular is CAM350. With this tool you can create a "Composite" that is the term given to generating a negative artwork from a positive gerber file.

    Basically the process is. Generate your gerber files of your PCB in the PCB editor then load those Gerber Files in the gerber editor. The gerber editor is used to generate the print files ! either positive or negative. Negative or composite as it is called in that tool is used to generate a plot that would be suitable for use with negative photo resist as is used in all board houses.

    I understand, I will try the recomended software CAM350 to manufacture my "composite" from my generated gerber files. Thanks.
