    Inner layer error on only one part IPC 356A output?

    wolferm

      Hello,

      I get this error when outputign IPC-356A netlist on only thi sone part as far as I can tell it is no different than any other thru hole part in design.

      This is only a two layer bare board.

      The report says

      IPC356 export report file.

      Export to file:.......

      Report Created on :....

       

      Warning: CAP_TH_RDL_L26_T9_LS22.5_LD.8 (Symbol): information about inner layers' data is not exported in 2 layers design!

       

      What the heck does this mean?

      Especially calling out only one decal, and why does it state (Symbol).

      I looked at the part type & decal and really can't see any difference in the way pad stacks were set vs any all other thru hole parts in this design?

       

      Help any ideas

      Could there really be an error in way decal was setup?

          It is an odd message; at least it is only a warning.  As you only have a two layer board with no inner layers I'm not sure why it is concerned about losing inner layer information.  Maybe there is an antipad defined for the inner layers or something?  Maybe it is a bug?  Did you try an ASCII export to see if anything extra shows up for the inner layers?

            Yes I tried an ascii out and back in only to have same warning on 356 output.

            I did think of possible pad stack defined diff on this one but no.

            Top, inner & Bot along with top solder & bot solder are defined and that is all  again a thru hole part.

            All the other thru hole parts are same too?

            I just love when this kind of stuff happens, brings into question the integrity of system/design in my mind even though only a warning.
