Description

• It is essential to keep Surface-Mount Devices (SMDs) dry from manufacturing point to the time of reflow soldering. Moisture Barrier Bag, also known as Vapor Barrier Bag, is made from multiple layers of plastic and aluminum that control moisture vapor leakage.

  Basically, there are 3 kinds of MBB, Tyvek MBB, AMBB and ANMBB, in the the market. The key factor of moisture barrier function of the bag is metal layer, like thickness of the foil layer, foil or metalized, etc., but thickness or material of other layers also can partially affect the quality of MBB.

  AMBB is a good choice for moisture sensitive devices and components. Depending on the products stored in the bag and the periods of storage, you have several selections on AMBB by adjusting the total thickness of the bag, the thickness of AL foil layer, etc.
