Planar transformer, Problem with pins
I'm struggling with a planar transformer.
When I check the PCB layers I get a warning (Fig.1)
"Problem: Connection to pin P3 cannot be provided without minimum distances violation. Fix: Please rearrange the pins position in order to provide the space for the tracks"
If I try to change anything I get the same warning and the previous value is restored.
I noticed that pin 1 is missing in the "Electrical Diagram" (Fig.2).
I also noticed that in the "Constructional Diagram" (Fig.3) and in the "Spiral Diagram" (Fig.4), pin 3 is twice, while pin 1 is missing.
The same problem is on the top PCB, when trying to select a different pin (Fig.5).
If I switch the "Split" (winding) from "Series" to "False", the problem is fixed as only 4 pins are used. However, you cannot get back from "False" to "Split". When I try again, a warning occurs and "Split" is returned to "False". Return "Split" design is only possible with "Undo".
Any suggestions on how to fix this?

Hi Tomeco,
The reason for the problem is that the original design was created with an older version of the software. A bug was found and corrected later which leaded to software upgrade.
I will return the fixed design on the e-mail.
If you stack with pins position you can use Reset Construction option in Menu/Action on the right bottom end of the screen.

Hi,
Thank you for using PI products.
This message appears when there is not enough space to place the connection between the winding and the pins. The minimum space required is TrackWidth + 2 Distance Track to Track.
From the pictures I can see that this is not the case for primary winding but I cannot check the secondary or bias.
Why Pin1 is missing I do not have an answer. I have new newer experienced similar behaviour and it needs investigation.
Please, provide a link or copy of your design here or on piexpert@power.com. Please add the name of this topic in the subject.
Best Regards,
