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. Since the spaced wall is designed so that no circle with the center of the substrate is present in the orthographic projection region projected onto the plane on which the substrate is located, the rotational trajectory of any point on the substrate within the shielding region corresponding to the spaced wall is not completely contained within the range of the orthographic projection region. Therefore, the electric field between any point on the substrate and the anode is never shielded by the spaced wall, and at the same time, the flow field of the electroplating solution in the shielding region on the substrate is not significantly reduced. As a result, abrupt changes in the thickness of the electroplating in the shielding region on the substrate are greatly reduced, and the change in the thickness of the electroplating becomes basically smooth.
