TLDR
In this paper, a method of ELECTRODEPODEPOSITING AMETAL COATING on DISCRETE CONDUCTIVE PORTIONS is described, where the contraints of the contours are contacted with a cathode fused of a valve METAL MATERIAL, which is able to function as an ELECTRODE but is passive to METAL de-position.
Abstract
A METHOD OF ELECTRODEPOSITING AMETAL COATING ON DISCRETE CONDUCTIVE PORTIONS IS DESCRIBED. THE METHOD COMPRISES IMMERSING THE DISCRETE CONDUCTIVE PORTIONS IN A STANDARD METAL PLATING BATH CONTAINING A SUITABLE ANODE. THE DISCRETE PORTIONS ARE THEN CONTACTED WITH A CATHODE FABRICATED OF A VALVE METAL MATERIAL, WHICH MATERIAL IS CAPABLE OF FUNCTIONING AS AN ELECTRODE BUT WHICH IS PASSIVE TO METAL DEPOSITION UPON ITS OWN SURFACES. A CURRENT DENSITY IS THEN MAINTAINED WITHIN THE PLATING SOLUTION WHICH IS SUFFICIENT TO METAL PLATE THE DISCRETE PORTONS TO A DESIRED THICKNESS. D R A W I N G

Method for forming printed circuits by elctroplating

TL;DR: In this paper, a cylindrical drum rotatable about a generally vertical axis and a tank for holding an electrolytic plating solution is used for continuously forming primed circuits. But the metal layer is masked to expose a plurality of patterns aligned along the web and a continuous strip of exposed metal along one edge of the web.

Method and device for electrolytically increasing the thickness of an electrically conductive pattern on a dielectric substrate.

TL;DR: In this paper, a method for increasing the thickness of an electrically conductive pattern on a dielectric substrate was proposed, comprising the steps of immersing the substrate with the pattern present thereon in an electrolytic bath, electrically contacting in the electrolytic body a negatively charged electrode during immersion of the substrate, and effecting contacting movement in the electrode and the pattern with respect to each other during immersion.
