    • The embodiments of the present disclosure provide an electroplating anode and an electroplating method using the electroplating anode. The electroplating anode and a cathode to be electroplated may form an electric field to deposit an electroplating layer on a surface of the cathode. A morphology of the cathode may be uneven. The electroplating anode may include an electrically conducting plate. A morphology of the electrically conducting plate may be in conformity with the morphology of the cathode. A protruding portion of the electrically conducting plate may correspond to a recessing portion of the cathode, and a recessing portion of the electrically conducting plate may correspond to a protruding portion of the cathode. Alternatively, the electroplating anode may include an electrically insulating backplate and a plurality of electrically conducting units. Each of the plurality of electrically conducting units may include a needle rod and a needle head that is configured at an end of the needle rod. The end of the needle rod with the needle head may be configured as an electroplating end of the electrically conducting unit. The electrically conducting unit may be fixed on the electrically insulating backplate by the needle rod. The plurality of electrically conducting units may be arranged in an array. Any two of the plurality of electrically conducting units may be electrically insulated from each other. The electric field between the electroplating anode and the cathode to be electroplated may be distributed uniformly, or the electric field in a local area may be strengthened or weakened.
