Through hole parts connected to the top layer

Plecto

Hi. I'm trying to make a board and then send it off to a board house for etching. I made the autorouter make the traces for me, both top and bottom traces with vias and all. The thing is that I have both SMT parts and through-hole parts on my board, but the autorouter doesn't seem to care. It sends top layer traces to my through-hole parts, how do I fix this?

  • I'm not sure if you got your answer.  I also had this question and this

    is what I did.

     

    From what I understand....

     

    Question: How do I prevent Eagle auto router to use through hole

    componenets as vias or join a top layer track to a through hole

    components pin.

     

    Answer:  Open and edit the library that holds your component you are

    using.  Edit the package (footprint) of the component that you are

    using.  You will have to do this for each component footprint that you

    are using.  When you are looking at the component and ready to edit,

    select the Rectangle button to draw rectangles and now select the layer

    you want to use.  In this case you want the tkeepout or bkeepout or

    trestrict or brestrict.  Each one can be used to mark an area that must

    not have any tracks.  tkeepout is for top layer, bkeepout is for bottom

    layer.  In your case, select the t, for top.  Now draw a rectangle over

    the pads, making sure its slightly bigger than the pad itself.  Save the

    library when done, refresh and voila.  Autorouter won't go near the top

    layer of the pin.
