Dry pack opening

After opening a dry pack, soldering should be done within 24 hours. SMD products stored

over the specified storage period need to be baked at 125 °C for 24 hours (under nitrogen

atmosphere). Devices packed in tubes or in tapes must be transferred to metal tubes before

baking whereas trays are bake able.
