Hello Techneters:

Please help out if you can--we have been unable to find anything on this.
Below is a forwarded message form one of our customers.

We need to take a temperature profile for flexible circuits (Flexes). I know
there is a procedure for taking temperature profiles for PCB's.
My question is if there a difference between a PCB thermal profile and a
Flex
thermal profile.
Are there anymore important criteria to check for besides 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 it
has
 not provided an 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.
