Abstract

Abstract An apparatus for use in selective plating a component, which apparatus comprises an electroplating zone, a series of movable selective plating heads in an endless chain configuration, wherein each plating head comprises an electrolyte opening, means for indexing the plating head to a component, means for engaging the component so as to expose an area to be selectively plated to electrolyte, means for releasably sealing the rear of the component in the region of the area to be plated, means for fastening the sealing means prior to the entry of the plating head into the electroplating zone and means for releasing the sealing means after the plating head leaves the electroplating zone, resilient or slidable couplings provided between the plating heads and means provided in the electroplating zone for supplying electrolyte to the area to be selectively plated, as well as a method of selective plating a component, which method comprises: providing an electroplating zone and moving through the electroplating zone a series of movable selective plating heads in an endless chain configuration, each plating head comprising an electrolyte opening, indexing a plating head to the component, engaging the component so as to expose an area to be selective plated, sealing the rear of the component in the region of the area to be plated, prior to the entry of the plating head into the electroplating zone, releasing the rear of the component after the plating head leaves the electroplating zone, providing resilient or slidable couplings between the plating heads and supplying, in the electroplating zone, electrolyte to the area to be selectively plated.

Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 138 words
An apparatus for use in selective plating a component, which apparatus comprises an electroplating zone, a series of movable selective plating heads in an endless chain configuration, wherein each plating head comprises an electrolyte opening, means for indexing the plating head to a component, means for engaging the component so as to expose an area to be selectively plated to electrolyte, means for releasably sealing the rear of the component in the region of the area to be plated, means for fastening the sealing means prior to the entry of the plating head into the electroplating zone and means for releasing the sealing means after the plating head leaves the electroplating zone, resilient or slidable couplings provided between the plating heads and means provided in the electroplating zone for supplying electrolyte to the area to be selectively plated.
Claim 2
Independent Claim 138 words
An apparatus for use in selective plating a component, which apparatus comprises an electroplating zone, a series of movable selective plating heads in an endless chain configuration, wherein each plating head comprises an electrolyte opening, means for indexing the plating head to a component, means for engaging the component so as to expose an area to be selectively plated to electrolyte, means for releasably sealing the rear of the component in the region of the area to be plated, means for fastening the sealing means prior to the entry of the plating head into the electroplating zone and means for releasing the sealing means after the plating head leaves the electroplating zone, resilient or slidable couplings provided between the plating heads and means provided in the electroplating zone for supplying electrolyte to the area to be selectively plated.
Claim 3
Dependent Claim 42 words
An apparatus according to claim 1, wherein the plating heads comprise track links having spring hinged lids, with electrolyte openings provided in the track links and pressure pads on the underside of the lid, the lids being biased into the open position.
Claim 4
Dependent Claim 37 words
An apparatus according to claim 1 or 2, wherein a plating tank is provided in the electroplating zone and wherein the plating heads comprise track lines which slide on tracks formed by walls of the plating tank.
Claim 5
Dependent Claim 31 words
An apparatus according to claim 3, wherein the spacing between two track lines of a plating head, and that between the tracks on which the track lines are slidable, is adjustable.
Claim 6
Dependent Claim 46 words
An apparatus according to claim 4, wherein the means for engaging the strip so as to expose, in use, the area to be selectively plated to electrolyte comprises a masking member insertable between the two track lines, and having one or more plating openings formed therein.
Claim 7
Dependent Claim 41 words
An apparatus according to claim 3, wherein the plating tank is provided with adjustable weirs, so that the flow of electrolyte to the plating zone can be adjusted in conjunction with the rate of flow of electrolyte into the plating tank.
Claim 8
Independent Claim 52 words
An apparatus according to claims 1 or 2, wherein the means for supplying electrolyte to the area to be selectively plated, and the electrolyte openings, comprise an elongate slot jet, and a corresponding slot formed in a lower part of each plating head and in which the elongate slot jet locates, respectively.
Claim 9
Independent Claim 123 words
A method of selective plating a component, which method comprises: providing an electroplating zone and moving through the electroplating zones a series of movable selective plating heads in an endless chain configuration, each plating head comprising an electrolyte opening, indexing a plating head to the component, engaging the component so as to expose an area to be selective plated, sealing the rear of the component in the region of the area to be plated, prior to the entry of the plating head into the electroplating zone, releasing the rear of the component after the plating head leaves the electroplating zone, providing resilient or slidable couplings between the plating heads and supplying, in the electroplating zone, electrolyte to the area to be selectively plated.
Claim 10
Independent Claim 123 words
A method of selective plating a component, which method comprises: providing an electroplating zone and moving through the electroplating zones a series of movable selective plating heads in an endless chain configuration, each plating head comprising an electrolyte opening, indexing a plating head to the component, engaging the component so as to expose an area to be selective plated, sealing the rear of the component in the region of the area to be plated, prior to the entry of the plating head into the electroplating zone, releasing the rear of the component after the plating head leaves the electroplating zone, providing resilient or slidable couplings between the plating heads and supplying, in the electroplating zone, electrolyte to the area to be selectively plated.
Claim 11
Dependent Claim 27 words
A method according to claim 8, wherein the component being plated is a strip of lead frames and wherein the strip is being selectively plated with silver.
Claim 12
Dependent Claim 17 words
A method according to claim 9, wherein the lead frames are indexed by means of slots therein.
