Abstract
A BGA is very susceptible to humidity and it should be used within eight hours of unpacking, but this is almost impossible in practical production. After carrying out a pre-dealing experiment on humidified BGAs, we come to the conclusion that a BGA which has been unpacked and remained in the air for more than eight hours must be dehumidified by means of being baked for 40 hours at a temperature of 125/spl deg/C in an oven.
