We had a case, when the PCBs were shipped overseas with no sealed plastic. It was CEM1 material that absorbed the moisture really fast. I know that moisture inside the laminate could cause a lot of trouble, such as outgassing during curing, wave soldering etc. But I can not find any formal recommendations or standards how to package PCB. Should we request vacuum sealed bags with the desiccant? Is the zip lock bag with no desiccant good enough to prevent the moisture absorption? Please, share you experience and knowledge. All inputs would be greatly appreciated.
