ROLL-TO-ROLL ELECTROLESS PLATING SYSTEM WITH MICRO-BUBBLE INJECTOR

摘要

A roll-to-roll electroless plating system including a reservoir containing plating solution. A web advance system advances a web of media though the plating solution in the reservoir, wherein a plating substance in the plating solution is plated onto predetermined locations on a surface of the web of media. A distribution system injects an inert gas into the plating solution to reduce the amount of dissolved oxygen. The distribution system includes an injector having a converging tube segment, a diverging tube segment downstream of the converging tube segment, a throat formed at a junction of the converging tube segment and the diverging tube segment, and an inlet for the inert gas in proximity to the throat.

1. A roll-to-roll electroless plating system, comprising:
a reservoir containing plating solution; a web advance system for advancing a web of media from an input roll through the plating solution in the reservoir to a take-up roll, wherein a plating substance in the plating solution is plated onto predetermined locations on a surface of the web of media as it is advanced through the plating solution in the reservoir; and a distribution system for injecting an inert gas into the plating solution, wherein the distribution system includes an injector for injecting the inert gas into the plating solution, wherein the injector includes:
a converging tube segment;a diverging tube segment downstream of the converging tube segment;a throat formed at a junction of the converging tube segment and the diverging tube segment; andan inlet for the inert gas in proximity to the throat.
