Routing into Multiple Layers

Rafa17

Hello Everyone,

I am working on a 5 layer design on OrCAD PCB Editor. The layers are stacked on each other and when routing I am going through each layer 1 at a time. I am trying to route a component from the top layer all the way to the bottom layer. When creating these clines from routing, I want to be able to create openings below or above these clines on the other copper layers. I tried using the void polygon option but creating these openings with the void option is becoming to complicated because of the angles that are created from routing. Is there a different way to route from layer to layer and then create openings on the others? The whole point of this is to create a route where if my cline is on layer 3 I want top and bottom to be the reference grounds. So, for top and bottom to be reference grounds, I need openings above and below the cline on layer 3.

  • u may try this.

     

    let us assume u have the following design on L3 of a 5-layer design.

     

    temporarily u need to make the cline wider on L3 for the openings of L2 nd L4.

     

    then u convert the cline to a shape.

    u can convert it to any unused conductor layer temporarily.

        

     

    the shape can be copied to the route keepout layers of L2 and L4.

     

    do not forget to put the cline back to the original width on L3.

    the image below is L3 and L2 overlaid.

     

    u may need to add a circular shape on the route keepout layers around the padstack.

     

    the below is L3 and L2 overlaid.

     

     u may want to adjust the fillet more.

     

    if u have multiple clines, u do not have to do them one by one but do them all at once by following the steps above.
