Has any one seen the IC Moisture Sensitivity derating curves that can be used
to determine the real maximum "out of bag" exposure times for plastic IC's ?
Example: Level 4 moisture sensitive parts are rated for 72 hours at 30C and
60%RH. At real shop environments of 21C and 30%RH, the real out of bag time
is 5 to 10 times longer for equivalent moisture absorbtion.

Does any one have the curves ?
