Hi,

I've been working into my Option file and I realized that the QFN & PQFN are in the same config section on the Components of the Option file.

The QFN and PQFN are not similar Footprint so, the pads type should be different on each case. The PQFN has the pads contacts under the body and the QFN has the contact under the body and in the lateral of the body.

As the pads on each case must be different I think they should be configured on a different section.
The same could happen with the SON & PSON components.

Best regards,
david
