Abstract
Articles carried by a carrier are processed in a sequence of processing steps that includes a plating step where a base layer of plating material is plated on a surface of the carrier. The plating material plated on the surface of the carrier is selectively stripped to partially remove the plating material to reduce e thickness of the base layer of plating material plated present on the surface of the carrier. A residual protective layer of plating material having the reduced thickness is left on the surface of the carrier.
Claims14
A method, comprising:
- processing articles carried by a carrier in a sequence of processing steps including at least one plating step wherein a base layer of plating material is plated on a surface of the carrier, and
- selectively stripping the plating material plated on said surface of the carrier to partially remove the plating layer and reduce a thickness of the base layer of plating material plated on the surface of the carrier leaving a residual protective layer of plating material on the surface of the carrier.
