and 60% rh when moisture proof bag is opened. 3.3 after opening the package msl conditions stated on page 1 of this spec should not be exceeded. 3.4 if the moisture sensitivity card indicates higher than acceptable moisture, the component should be baked at min. 60deg +/-5deg for 24 hours. 4. iron soldering hand soldering is not recommended for regular production. these guidelines are for rework only. soldering iron tip should contact each terminal no more than 3 sec at 350
, using soldering iron with nominal power less than 25w. allow min. 2 sec. between soldering intervals. 5. usage do not exceed the values given in this specification.
