     Hi,

    You need to define the smd padstack on the bottom. The testprep doesn;t mirror a normal smd pad to the bottom.  Start by creating a thru hile padstack then Null the top and inner layers. 

    Next set the padstack to single layer with only the botton defined. Save with a unique name smd_c30_tp_bot.pad 

    That should work.
