This invention discloses a surface-mount solid aluminum electrolytic capacitor and its manufacturing method, comprising a capacitor core package, which includes N capacitor cores, N+1 conductive metal meshes, a substrate, anode leads, cathode leads, and a silver paste covering tape. The capacitor core package is encapsulated and electroplated to form a solid aluminum electrolytic capacitor. The capacitor core includes an anode portion, a cathode portion, and an insulating barrier tape. In this invention, the conductive metal mesh sandwiched between the metal pads in the anode portion of the capacitor core and the cathode portion of the capacitor core can achieve the flatness of the core package. The silver paste covering tape located on the side of the cathode portion of the core package is embedded in the gap formed between two adjacent capacitor cores due to the conductive metal mesh sandwiched, forming an integrated connection. This prevents the resin encapsulant from being squeezed into the core layers during encapsulation, preventing core deformation damage that could lead to increased leakage current and increased ESR. Furthermore, it can prevent insufficient capacitance or even capacitor failure caused by delamination between cores.
