Hello, I am working on a PCB with 4 layers, but the componets is only on top. In layer definition I set that all 4 layer are split mixed, but only Top is set as components layer, Bottom is set as routing layer.
When I make a fabrication check the message below is displayed and in the two cam documents are insert beetween the cam documents. Why? I have a wrong layers setup or wrong cam setting?
Because you don't have component on Bottom Side, you probably did not set a CAM Layer for PasteMask and Silkscreen Bottom ... and that is ok.
