    POPCORN PREVENTION
    MSD Protection Steps Per J-STD-033B.1
    ICs can act like a sponge. If they have semi-permeable membranes, moisture from the ambient air can get into those devices. When they get rapidly heated during reflow or rework, the result is rapid outgassing. In some cases, this excessive outgassing causes popcorning, which can damage the internal structures of a component. This how-to helps prevent and rid moisture from components.
