Hello Technet:

We need to take a temperature profile for flexible circuits (Flexes). I know
there is
a procedure on taking temperature profiles for PCB's.
My question is there a difference between a PCB thermal profile with a Flex
thermal profile.
Are there anymore important criteria to check for besides checking peak
temperature, time above reflow and ramp rate. I would appreciate it if you
could help provide this information.
We are currently using Datapaq's Reflow Tracker to track our profile but
have not provided accurate thermal profile. Do you
know whom I can contact? I would appreciate if you could help us. I look
forward to hearing from you.
