Selective plating mask member and selective plating method

Abstract

There are provided a selective plating mask member including: a drum-shaped jig having a jig opening arrangement region which is a region having a jig opening portion that communicates an outer side surface with an inner side surface of the drum-shaped jig, that is a strip shaped recess provided along a circumferential direction on the outer side surface; and a mask that embeds the jig opening arrangement region and has a mask opening at a location corresponding to the jig opening, wherein the mask is placed in the jig opening arrangement region, a through hole composed of the jig opening and the mask opening is provided, and an edge of the mask opening is raised toward outside of the drum-shaped jig, and there is provided a related technique thereof.

1 . A selective plating mask member, comprising:
 a drum-shaped jig having a jig opening arrangement region which is a region having a jig opening portion that communicates an outer side surface with an inner side surface of the drum-shaped jig, that is a strip shaped recess provided along a circumferential direction on the outer side surface; and   a mask that embeds the jig opening arrangement region and has a mask opening at a location corresponding to the jig opening,   wherein the mask is placed in the jig opening arrangement region,   a through hole composed of the jig opening and the mask opening is provided, and   an edge of the mask opening is raised toward outside of the drum-shaped jig.   
     
     
         2 . The selective plating mask member according to  claim 1 , wherein at least the edge of the mask opening of the mask is made of rubber. 
     
     
         3 . The selective plating mask member according to  claim 1 , wherein in the jig opening arrangement region, a plurality of the jig openings are placed along the circumferential direction. 
     
     
         4 . The selective plating mask member according to  claim 1 ,
 wherein in the drum-shaped jig, the jig openings are placed in a predetermined pattern, and   the mask has a plurality of parts lined up each having n mask units (n is a natural number) corresponding to pattern units of the predetermined pattern.   
     
     
         5 . The selective plating mask member according to  claim 1 , wherein the jig opening arrangement region is a recess provided in a strip shape around an entire circumference of the drum-shaped jig, that is, on an outer side surface of the drum-shaped jig. 
     
     
         6 . The selective plating mask member according to  claim 1 , wherein a plurality of rows of combinations of the jig opening arrangement region and the mask are placed in a vertical direction of the drum-shaped jig. 
     
     
         7 . The selective plating mask member according to  claim 1 , wherein in the drum-shaped jig, the jig opening arrangement region includes:
 a non-penetrating groove; and   a relatively convex region,   wherein a back side of the mask has a shape that fits into the groove and the relatively convex region.   
     
     
         8 . The selective plating mask member according to  claim 1 , wherein the mask opening coincides with the jig opening or at least selectively covers the jig opening. 
     
     
         9 . A selective plating method, comprising:
 bringing a plating solution into contact with a workpiece through the through hole, the workpiece being wrapped around the selective plating mask member according to  claim 1 ; and   applying plating to the workpiece.
