    purpose of some layers and differences between them

    mfolejewski

      Hello everyone, I have a few questions about Mentor Xpedition PCB.

       

      1. In xPCB Layout: I notice that some components have additional layer: Metalization Area. What is the purpose?

       

      2.

      In Fablink:

      - what are the differences between the two layers: Panel Outline and Panel Border?

      - what are the differences between the two layers: Scoring Line and Shearing Line? Which one should I use to draw v-cut line?

       

      3. In xPCB Layout: what is the difference between Fix / Semi Fix / Lock attributes?

          Hi mfolejewski,

           

          Here some answers

          1. The metalization area is a surface of copper that is similar to a plane shape, but does not need to have a net name while it is designed. IT is moslty used in Librarian to design a part with a surface for contact. Think for example of a heat sinking surface under the chip.
          2. In Fablink you put together boards.
            1. Panel boarder, is the physical dimension of the board composed of many boards.
            2. Panel outline is the outline that carries the information forward, complete with elements that exceeds the panel boarder.
            3. Scoring line is the line where the v-cut will be made
            4. Shearing line is the path to follow to cut it.
          3. This are different way of protecting an item for modifications
            1. Fix, will not be moved until unfixed
            2. Semi Fix, will not be moved by outside object, but can still be moved
            3. Lock is stronger that fix.

           

          Hope this helps
