What is mean by Ambien temperature?

Hi,

I am calculating stress analysis of IC
I need to understand the concept of Ambient Temperature?
Can Ambient temperature can be Min Ambient Temperature or Max Ambient temperature?

DC

Ambient, the environment here and now. Whatever
touches the device. Ambient air however has other
key attributes such as flow.

A device's attributes (as listed) are specified between
min and max temperatures. Case temp is used in the
HiRel / military parts worlds because it can be exactly
forced and measured. Which is key since you've got
delta limits besides.

Anyway, between min and max temp as specified
(perhaps a JEDEC callout, you'd have to do the digging
and lots of companies don't have very good info in
the "first layer" product documentation, unless you get
into the more-testing grades) the performance and reliability
limits in the tables are "guaranteed"* to apply. Outside
they may or may not, it's on you.

* Ha, ha. Read the fine print.

Ambient temperature 0 - 70C is a common commercial
range and you should realize that on many low cost
commercial parts there is no testing done after packaging.
Just probe and pick to wafer map all robo-style.

A higher grade might see actual package test.
