Steve: No, it will decompose at those times and temperatures. Can you use a
lower temp bonding agent? You might be able to get away with 200 F for 30
minutes depending on what flavor ENTEK you're using.
Of course a lot depends on what type of flux, duration and the number of
thermal exposures it will see in assembly.

Subject: [TN] OSP Question
Good afternoon,
I have a question on the thermal characteristics of Entek OSP. We have a
flex circuit which requires OSP as the finish. We intend to do the OSP
operation but then we have to thermally bond a rigid stiffener on the flex.
OSP will see pressure and a temperature of approx. 350 F for 1 hour. Will
the OSP handle this. Thanks for your help. Regards Steve Kelly
