4 Layer Rigid 2 layer flex PCB

Hi 

I have a 4 layer (Top, Layer1, Layer2, Bottom) rigid board and the internal 2 layers(Layer1, Layer2) from this rigid pcb continue as flex PCB. I have to order a stencil for this board.

I can generate gerber files for solder paste top and bottom but i cannot find any pastemask_layer1 and pastemask_layer2 as there are some pads i need to apply solder paste on. So i was wondering which options i have to check here for generating the solder paste files for these layers.

    Look under the Rigid flex class and you should see the layers you need to enable

    So if they are not there you need to add them to the cross section - right click - Add Layers then look under Design defined mask layers - other and they should be there to add. They wil, then appear under the Geometry class

    It uses the EmbGeo class (embedded Geometry) because it's an internal layer. No issues here this is fine. Turn on the layer to ensure it displays what you want.
