Abstract

This invention discloses a method to form multilevel pattern on the aluminum compound board surface, which comprises the following steps: providing one aluminum compound material metal board materials and forming first ink pattern on the metal surface; making first etching on the metal board to form first pattern on the shielding area of the first ink pattern; forming second ink pattern on the metal surface; making second etching on the metal board to form second pattern on the shielding area of the second ink pattern; removing the first and second ink patterns; processing the metal board by positive electrode and sealing its opening.

Description

technical field [0001] The invention relates to a method for manufacturing a multilayer pattern, in particular to a method for forming a multilayer pattern on the surface of an aluminum composite plate. Background technique [0002] For 3C products such as computers, communications, and consumer electronics, in addition to the requirements for speed and functionality, in order to adapt to the development trend of consumers who pay attention to metal textures, high-end products gradually use metal casings as the mainstream. The use of metal materials has four advantages: good electromagnetic shielding effect, good heat dissipation, good rigidity, impact resistance, etc., and also has strength protection and environmental protection characteristics of recyclability. [0003] In order to change the surface properties of metal casings, such as giving metal luster and beauty, anti-rust or anti-wear, etc. The surface treatment technology of the metal casing has attracted much att...
