Abstract
PURPOSE: To obtain uniform thickness of metal part crystallized by electrodeposition by forming small circular holes other than a hole of the shape of part in a photosensitive and chemical resistant film coated on a base plate.
CONSTITUTION: The photosensitive and chemical resistant film 12 is coated on the matrix metal base plate 11, exposed to light by photographic processing, and then removed by dissolution by a developing solution to form the hole 13 of the shape of part. At the same time, a plural number of small circular holes 14 in such a way that ratio of the base plate exposed area of the hole 13 portion to the insulating area of the photosensitive and chemical resistant film 12 is almost uniform. Thus, current line in electrodeposition process is distributed even into the small circular hole 14, whereby the current density in a portion of a broad exposure width becomes similar to that in a portion of a shallow exposure width and thus the thickness of crystallized metal part becomes uniform. In addition, electrodeposition stress becomes almost constant and thus the control of electrodeposition stress can be made easier by electrodeposition conditions. Furthermore, no secondary processing such as buffing, etc., is required because of uniform crystallization of metal part.
