We have a customer that wants us to begin using vaccuum sealed wrapping to ship their boards in. They want to reduce moisture absorbtion in the board. It's been awhile, but I remember reading that this is a "No-No". I don't remember WHY but I think it had to do with trapped moisture. Could anyone let me know if this is or isn't recommended and also why?
