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 ?
