Embodiment Construction

[0016] see figure 1 and figure 2 , the manufacturing method of the housing 10 in a preferred embodiment of the present invention includes the following steps:

[0017] A substrate 11 is provided, and the substrate 11 can be glass, ceramics or stainless steel.

[0018] Clean the surface of the substrate 11 to remove impurities and oil stains on the surface of the substrate 11, and dry it for later use after cleaning. The cleaning includes putting the substrate 11 into an ultrasonic cleaner filled with ethanol or acetone solution for vibration cleaning.

[0019] The substrate 11 after cleaning is fixed on the turntable of a magnetron sputtering coating machine (not shown), and the vacuum chamber of this magnetron sputtering coating machine is vacuumized so that the pressure in the vacuum chamber is 3× 10 -8 Pa, after that, argon gas (working gas) with a flow rate of 100-400 sccm (standard state ml / min) is introduced; and the temperature of the cavity is kept at about 100-20...

Abstract

The invention provides a manufacture method of a shell, which comprises the steps of: providing a substrate; forming a color layer on the surface of the substrate by a magnetic sputtering method; then arranging a moveable baffle at the front end of a metal target, and powering on the power supply of the target, wherein the target is any one of a titanium target, a chromium target or a zirconium target; adjusting the baffle right ahead the target, and depositing for a certain time; sputtering target atoms on the baffle and removing the baffle when the number of atoms sputtered on the target and the sputtering speed are stable, so that the target atoms are sputtered on the substrate; after continuously sputtering for a period of time, powering off the power supply of the target; depositing and remaining a pattern layer on the surface of the color layer in the nucleation stage to form the pattern layer on the color layer. The shell manufactured by the manufacture method disclosed by the invention comprises the substrate, the color layer and the pattern layer, wherein the color layer is formed on the surface of the substrate, the pattern layer is formed on the surface of the color layer, and the pattern layer is a Ti, Cr or Zr film layer.

Description

technical field [0001] The invention relates to a manufacturing method of a shell and a shell made by the method. Background technique [0002] With the continuous advancement of technology, various electronic devices such as mobile phones and computers are also developing rapidly, and their functions are becoming more and more abundant. In order to make the design of the appearance pattern of the electronic device more colorful, traditionally, a pattern can be formed on the surface of the casing by pad printing, printing or laser engraving, or a pattern layer can be formed on the surface of the casing of the electronic device by spraying paint. Presents a good appearance. [0003] Magnetron sputtering technology is more and more widely used in the field of decorative coating because of its environmental protection and the appearance of the prepared film has a very metallic texture. At present, the method of forming a pattern layer on the housing of an electronic device by...
