  • a pair of slip-out preventing pieces 52 , 52 are provided on a top face of the accommodating concave portion 51 such that the center portions of those pieces 52 , 52 are tilted downward and oppose each other in order to prevent the object product to be plated W from dropping out when the same object products to be plated W are put into the accommodating concave portions 51 .
  • the bottom portion and side portions of the accommodating concave portion 51 are cut out at positions of the slip-out preventing pieces 52 , 52 so that a through opening 53 is formed.
  • the through opening 53 in the respective accommodating concave portion 51 is formed continuously in the longitudinal direction of the carrier tape.
  • Narrow slits 54 , 54 are formed through at least in the bottom and side faces of each accommodating concave portion 51 so that washing solution or plating solution escapes easily.
  • the washing solution or plating solution can flow into the accommodating concave portion 51 excellently through the opening 53 and the slits 54 , so that the washing solution or plating solution can flow into or out the accommodating concave portion 51 easily.
  • Feeding holes 55 , 55 are formed through on both sides in the width direction of the carrier tape 5 at a specific interval in the length direction. Said feeding sprocket 6 engages these feeding holes 55 , 55 and when the feeding sprocket 6 is rotated, the carrier tape 5 is fed successively from the upstream to the downstream.
  • FIG. 4 shows a schematic structure diagram of the plating unit 2 and the plating unit 2 contains a cell 8 filled with plating solution and a cathode member 9 is provided within this cell 8 .
  • This cathode member 9 is provided from the upstream to the downstream in the cell 8 along the flow direction of the carrier tape 5 and connected to a cathode of an outside power supply.
  • a copper plate 10 connected to an anode of a power supply, is disposed on a side of the cell 8 .
  • the object product to be plated W is plated with copper and the cell 8 is filled with plating solution 11 composed of copper sulfate solution.
  • the cathode member 9 is fit to the opening 53 in the carrier tape 5 and then, the carrier tape 5 is fed from the upstream to the downstream along the cathode member 9 in a condition that the carrier tape 5 rides on the cathode member 9 .
  • FIG. 5 is a schematic structure diagram showing the condition in the plating solution in enlargement.
  • the top face of the object product to be plated W accommodated in each accommodating concave portion 51 in the carrier tape 5 is pressed to the slip-out preventing pieces 52 , 52 . Consequently, the cathode member 9 invades into the opening 53 so that this cathode member 9 comes into a contact with the bottom face of the object product to be plated W accommodated in each accommodating concave portion 51 .
  • minus current is supplied to the object product to be plated W through the cathode member 9 , so that the object product to be plated W is charged with negative electricity.
  • the copper plate 10 on the anode side is dissolved and copper plating layer is formed on the surface of each object product to be plated W successively.
  • the carrier tape 5 is fed slowly in the cell 8 such that it is dipped in the plating solution 11 for about 10 minutes, copper plating is achieved on each object product to be plated W excellently within the cell 8 .
  • the plating solution 11 is nickel sulfate solution and instead of the copper plate, a nickel plate is employed. Additionally, silver plating, gold plating, galvanization, chrome plating and the like can be carried out in similar ways.

Consequently, the plating treatment can be carried out continuously and effectively while the carrier tape is fed.
  • the carrier tape can be used by a charging unit in plant or the like just as it is and the effectively plated products can be transferred to a next production stage without any delay.
  • washing units are disposed in the upstream and downstream of the plating unit and each object product to be plated is washed when it passes through each washing unit, washing in a process before plating and washing in a process after plating can be carried out continuously in a condition that the object product to be plated is kept in the carrier tape.
