Sheet type precious metal product manufacturing method and product

The invention relates to a sheet type precious metal product manufacturing method and a product, and the method comprises the following steps: 1, material selection: selecting an anode material, a cathode material and a precious metal salt solution material, the cathode material being made of a conductive material which does not react with the precious metal material and is easy to strip from the precious metal material; a conductive material is selected as the anode material; a conventional precious metal salt solution capable of separating out precious metal in a power-on state is selected as a precious metal salt solution material; 2, plate manufacturing, specifically, plate manufacturing is conducted on the cathode material according to a preset pattern; 3, electrified deposition: direct current is introduced between the anode material and the cathode material for electrochemical reaction, and the noble metal material is deposited on an electrified area on the cathode material through the electrochemical
