I'm not sure if technically there can be a single correct
specification-based answer. It would seem that the end application
drives the proper choice here, so it seems that input from the customer
will be required.

Subject: [IPC-600-6012] mixed stack thermal shock temps

Hi everyone,
We are testing product for a 6012 contract, but the product is mixed
Rogers/GF.
6012 Optional Thermal Shock is required, but no other advise is given.

So, in your opinion do we run it at:

-40/85 (GX/GY)
-55/125 (GF)
-65/105 (6018A) ?

I know, ask the end customer, but I'm wondering what the answer is from
a broader industry perspective.

Thanks,
Chris
