Preparation method of solid aluminum electrolytic capacitor capable of preventing short circuit

The invention relates to a preparation method of a solid aluminum electrolytic capacitor capable of preventing short circuit, which belongs to the technical field of aluminum electrolytic capacitors and comprises the following steps of cutting, core package winding, element welding, formation, impregnation, post-treatment, assembly and finished product preparation. According to the prepared solid aluminum electrolytic capacitor, the adhesive tape, the positive electrode foil, the electrolytic paper and the negative electrode foil are stacked and wound in sequence to form the capacitor core cladding, the outer layer of the core cladding is wrapped with the insulating layer, and the core cladding and the insulating layer are impregnated together to enhance the structural strength of the core cladding; according to the invention, when the SMD product is over high temperature, the assembly still keeps the original characteristics of the product, and meanwhile, the external structure of the core package is enhance
