Hi EG,
You did not say what you are trying to accomplish with an environmental
stress screening of -15 to 60 deg C. As ESS goes, this is not much of a
screen, and I am seriously wondering if you accomplish anything at all. What
you do may serve as a Burn-In, but I can not imagine what latent defects you
would screen out with -15 to 60 deg C cycling—compliant pins or not— unless
you run it long enough to damage good product.
