How to place topside pad over a bottomside pad

autodeskguest

I need to make a new component for an Optek OP124 pill pack diode.  This is

a tiny bullet shaped package designed to be placed in a hole drilled between

the top and bottom sides.  Tthe top side is anode, the bottom side is

cathode.  There must be no plating in the hole.

 

I can place an SMD pad on the bottom layer and another SMD pad on the top

layer.  I can then place a hole of 1.8mm diameter through the pair of pads.

If I place the pads exactly over one another I cannot name the pads.  If  I

displace them 0.1 mm I can then name the pads.

 

When I try to route the component, EAGLE shows the air wires going to the

correct places but it never draws the traces and fails to route.  I have

tried AUTO with grids down to 1 thousandth but it never routes.

 

Any been able to make a component that goes inside the board between solder

and component layers?

 

Cheers

Brian

    The board house I use don't actually require two separate drill files,

    but they do require that I note which drill numbers are PTH and which

    are not. So far this has worked fine, but I could imagine a potential

    problem if I had the same size hole in both types.
