The present invention discloses an electroplating apparatus comprising a film frame having an intermediate passage and a spaced wall that limits the intermediate passage, wherein no circle with the center of the substrate is present in the orthographic projection region projected onto the substrate position by the spaced wall. When the substrate undergoes the electroplating process in the electroplating apparatus, the rotational trajectory formed from any point on the substrate within the shielding region corresponding to the spaced wall becomes a circle with the center of the substrate.
