axlDBCreatePadStack Warnings...

mikebystedt
Hi All, have any of you seen these errors before?  I'm getting closer and closer to creating my padstacks,
but still get some warnings that don't seem to point me in the right direction. (I'm a programmer and new to
pcb design).  My current function to copy padstacks is listed below.

I'm seeing things like the following:
- W- *WARNING* (axlDBCreatePadStack): Hole larger than pad size on layer FILMMASKTOP
- W- *WARNING* (axlDBCreatePadStack): Padstack origin outside pad boundary on layer TOP

I'm assuming that they must be the figureSizes for the drillData and the Pad data.  The wording of the messages
don't really give me too many hints on what to next to resolve these.  Again, I'm new to this, and especially to the
createPadStack function.  

Any help is greatly appreciated!

-Mike

  • Both those "errors" are just warnings so you could ignore them.

    There is no problem having some pads smaller than the hole. This is common with etch on unplated holes.

    The "Padstack origin outside pad boundary" is probably due to a large offset on the source pad. This is OK but it's a warning you should review.
