ELECTROCHEMICAL STRIP AND MANUFACTURING METHOD THEREOF

摘要

An electrochemical strip is disclosed. The electrochemical strip includes a substrate and an electrode deposited on the substrate. The electrode includes a conductive paste layer, a first metal layer, a second metal layer, a third metal layer, and a fourth metal layer. The conductive paste is made of a material selected from the group consisting of copper paste, nickel paste, silver paste, and silver-carbon paste. The first metal layer is made of a group VIII metal. The second metal layer is made of nickel. The third metal layer is made of a group VIII metal. The fourth metal layer is made of a material selected from the group consisting of palladium, gold, and platinum.

主权项

1. A manufacturing method of an electrochemical strip, comprising steps of:
providing a substrate; and disposing an electrode layer on the substrate, which comprising steps of:
printing a conductive paste layer on the substrate;printing a carbon layer on a first region of the conductive paste layer;etching a second region excluding the first region of the conductive paste layer;chemically plating a first metal layer on the second region of the conductive paste layer;chemically plating a second metal layer on the first metal layer;chemically plating a third metal layer on the second metal layer; andchemically plating a fourth metal layer on the third metal layer;wherein the first metal layer is made of a group VIII metal, the second metal layer is made of nickel (Ni), the third metal layer is made of a group VIII metal, and the fourth metal layer is made of a metal selected from the group consisting of palladium (Pd), gold (Au) and platinum (Pt).
