I agree that the stated use is bad for non-fiber reinforced polyimide (Kapton tape). It can easily be punctured by sharp objects. FR4 is much better. I would also recommend removing points from the offending leads.

The lead protrusion is very slight but it the cover just sit very close at the one end. Kapton type tape does not provide sufficient protection. Is there any other material that is thin but more resilient and has insulation properties? The assembly will not be coated. This assembly goes into to test station that will be used by our customer.
