Dear Technical Representative,
Do you know of any specifications that outline the need to moisture
bake multilayer (PTH,SMT,or mixed technology) PCB's? I am trying to
conduct a literature search on such requirement. I have concluded, so
far, that moisture baking boards prior to assembly was a preventive
method used to minimize yield problems such as blow-holes on boards
subjected to high humidity for several months. Which leads to another
question how is high humidity defined? How long should a board be
stored prior to use?
