    Hello,

    If the units were received in a vacuum sealed ESD bag with the tape and reel enclosed (or have not been out of the sealed bag for more than a year), then a bake out should not be necessary. Otherwise I would recommend an 8 hour bake out at 150C followed by a resealing before installation. 

    Regards,
