Hi Chris,
I do not care for thermal shock as a requirement—it is o.k. for design purposes, but as a requirement it is meaningless in assuring product reliability.

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
