Peel strengths for PTFE on Woven E-glass, Non-Woven E-glass, and ceramic
filled materials are covered in IPC-L-125A, "Specificaiton for Plastic
Substrates Clad or Unclad for High Speed/High Frequency
Interconnections". This document does a better job in establishing the
requirements for PTFE materials than MIL-S-13949 does.
Peel strength requirements have been established for after thermal stress
and after exposure to elevated temperature.
IPC-L-125A sells for $15 to member companies and $30 to non members. You
can contact our order department on X318
