Abstract

The present invention relates to a plating jig, and more particularly to a plating jig capable of cutting off the current from the substrate current section so as not to allow the plating solution to flow into the current section that applies electricity to the substrate. A plating jig capable of cutting off the liquid of a substrate current-carrying portion according to the present invention comprises: a first plate and a second plate arranged with a substrate in between; a first internal sealing member mounted in a closed-loop shape along the perimeter of a first perforation hole formed in the first plate and contacting along the perimeter of one surface of the substrate; a second internal sealing member mounted in a closed-loop shape along the perimeter of a second perforation hole formed in the second plate and contacting along the perimeter of the other surface of the substrate; and an external sealing member in a closed-loop shape disposed between the first plate and the second plate at the outer edge of the substrate to seal the gap between the first plate and the second plate. The apparatus comprises a conductive member that is mounted on the other side of the first plate between the first inner sealing member and the outer sealing member, or mounted on one side of the second plate between the second inner sealing member and the outer sealing member, and is electrically connected to an external power source; wherein, when the substrate is positioned between the first plate and the second plate, the edge portion of the substrate positioned inside the outer sealing member contacts the conductive member.

Description

Plating jig capable of cutting the current-carrying part of a substrate The present invention relates to a plating jig capable of cutting off the liquid in the current-carrying part of a substrate, and in particular, to a plating jig capable of cutting off the liquid in the current-carrying part of a substrate so as not to have the plating solution flow into the current-carrying part that applies electricity to the substrate. A plating device for plating substrates such as printed circuit boards is equipped with a jig for holding the substrate. A clamp is attached to the above jig, and the jig holds a substrate by means of the clamp. When plating the above substrate, the current supplied through the jig is transmitted to the substrate through the jig and the clamp so that an electroplated layer is formed on the substrate. Conventional plating devices of this type had the following problems. Basically, the jig holding the substrate is immersed in the plating solution along with the substrate. Therefore, plating was inevitably carried out on the contact points that become submerged in the plating solution along with the substrate during plating, namely the electrical contact points between the clamp and the substrate. When this phenomenon accumulates, a problem arises where the clamp and the substrate become stuck together and do not detach easily. To prevent this problem, the jig and clamp had to be periodically stripped to prevent plating from accumulating at the contact points. In addition, due to resistance generated at the clamp contact points and uneven current distribution within the product, plating became concentrated in areas adjacent to the contact points, resulting in thick plating; this affected the overall plating variation of the product and became a factor in degrading product quality. Although various technologies have been developed to solve these problems, the aforementioned issues still exist.
