As a result, it is positioned at the center between the upper plating electrode 12 and the lower plating electrode 14 by itself.
  • the edge mask 40 when the edge mask 40 is installed in the horizontal cell 10, the edge mask 40 does not have a hard work of centering the edge mask 40 on the center between the upper plating electrode 12 and the lower plating electrode 14. Only the quantity (installation tolerance) can be set to proceed.
  • the edge mask 40 is not exactly positioned at the center between the upper plating electrode 12 and the lower plating electrode 14 during installation, the plating solution flowing up and down of the edge mask 40 in accordance with the discharge of the plating solution as described above. The pressure causes the edge mask 40 to be placed in the center position.
  • the edge mask 40 according to the present embodiment has shown the cross section of the discharge passage 50 or the upper and lower channels 56, 58 in a rectangular or rectangular shape, the edge mask of the present invention In the cross section of the passage and the like is not limited to such a shape, but may be variously modified within the scope of the present invention to a circular, elliptical or trapezoidal shape.

Abstract

L'invention concerne un masque de bord d'un appareil d'électrodéposition à cellule horizontale, doté d'une structure comprenant : une partie d'évidement qui est déformée de manière concave de façon à entourer un bord d'une plaque d'acier sur une surface tournée vers le bord de la plaque d'acier, afin de placer un masque de bord dans la partie centrale d'une cellule horizontale à l'aide de l'écoulement d'une solution de placage ; et plusieurs chemins de décharge, formés le long de la partie d'évidement de façon à être en communication avec la partie d'évidement, pour décharger la solution de revêtement électrolytique, une sortie du chemin de décharge étant formée en tant que surface supérieure d'un masque de bord faisant face à une électrode métallisée supérieure et/ou en tant que surface inférieure d'un masque de bord faisant face à une électrode métallisée inférieure, de telle sorte que la solution de placage est déchargée entre la surface supérieure du masque de bord et l'électrode métallisée supérieure et/ou la surface inférieure du masque de bord et l'électrode métallisée inférieure.
