OrCAD PCB - "Hidden & Deleted Pins" in TO DPAK

   Hi Tom

I guess we are not talking about the same thing right now. I guess you were looking at my last post with attached pictures, posted on 22 Feb 2013 at 8:51am. This "problem" indeed was my mistake since I was using "hide/remove" incorrectly.
My main problem is shown at the end of the post that started this thread (see the following pictures). 
This is how the footprint looks before importing it to our library:

And this how it looks like when I reload it:

If I don't use the renumbering feature, then the middle pad stays removed.
Today I tested it on a different Computer and got the same effect as described above.

Regards
Daniel

	Sorry, it did not work out. The pad is still showing up in the FPE Viewer after saving it to FPX. I tried hide and remove with a new (and thus empty) library. Steps to reproduce - Regards, Daniel

	Daniel, Are you saying that "Save to FPX" and retrieve from FPX is not working? Or building the DPAK in OrCAD PCB is not working?

	Hi Tom, Yes, saving and retrieving from the fpx-library is the problem. Somehow FE seems to "forget", that a pin is removed when the numbering of the pins is not standard. As for the export to OrCAD: I built the part, with renumbering and removing the pad, and then let FE create the footprint (without saving it to any library first). The result is OK. The renumerbing and the missing pin are created correctly. So, the export to OrCAD works. Regards, Daniel

	OK, we're categorizing this as user error in the tool. You're not supposed to renumber the pins the way you did 1, 4, 2 & 3 is the thermal pad and then delete Pin 4. You're supposed to take the normal part pins 1, 2, 3, 4 and "Remove" pin 2 and the final pin assignment will be 1, 2 & 3 is the thermal pad.

	Alternately, you can change the number of pins to 3 and double the pitch.

	Hi Everybody In the final pin assignment, the thermal pad has be to pin 2. So using the standard footprint and then remove pin 2 does not help. What worked out, however, is setting the number of pins to 3 and doubling the pitch. Thanx for you help and your patience Regards Daniel
