Abstract
A negative-pressure packaging method for aluminum electrolytic capacitors including: penetratedly arranging a capacitor element in a seal; placing the capacitor element, the seal and a case at an inner chamber of an accommodating mechanism; sealing the accommodating mechanism; vacuumizing the accommodating mechanism to allow the inner chamber to be in a negative pressure state; subjecting the seal and the case to packaging, such that the seal is located at a first depth of the case; and subjecting the seal and the case to pressing, such that the seal is located at a second depth of the case, where the second depth is closer to a bottom of the case with respect to the first depth.
