(2) process 42-DL232 in a clean room with proper temperature and humidity. (3) ground all working machines and workers wear anti-electrostatic ring to ground during processing. (4) avoid contact 42-DL232 with bare hands .if unavoided, wear anti -electrostatic ring and use anti-electrostatic t ool to pick it up. guaranted temperature and retention cycle (1) the device/wafer 42-DL232 should be stored in the nitrogenous chest. the conditions suggested are as follows: temperature = 23 3 relative humidity = 50 10% minimum nitrogen inflow = 3 liters/minute (2) if the device/wafer, 42-DL232 is incidentally exposed to the air, use it for manufacturing as soon as possible. (3) under the storage environment specified in item (1), six-month safe storage period is guaranteed.
