Jon,

 Nomex is pretty tough and in thick layers (20mil) you would have to have a
sharp lead or plenty of pressure. Of course FR4. A piece of ceramic material
would be REALLY hard, nothing will cut through that but it is brittle.

 Just ideas you probably already thought of.

Subject: [TN] SEEKING A VERY THIN INSULATING MATERIALS

Hopefully, some of you have experience during design where the connector
lead protrusion is long enough to touch a metal cover.  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.
Thanks in advance.   Jon
