Abstract
The invention provides the preparation method of a kind of mobile phone back panel with antenna, comprise the following steps: step 1, offer glass back of the body screen；Step 2, by can metalization ink be screen printed onto on glass back of the body screen according to designed antenna pattern, form ink layer after drying, described can be containing chemical plating active substance in metalization ink；Described ink layer is radiated by step 3, employing energy beam, exposes chemical plating active substance, is formed and chemically plate activating area；Step 4, carry out electroless copper on the described surface chemically plating activating area, glass back of the body screen forms copper facing antenna stack.Present invention also offers the mobile phone back panel with antenna made by above-mentioned preparation method, shield including the glass back of the body and be formed at the antenna on described glass back of the body screen, described antenna is copper facing antenna.The preparation method of the present invention is capable of making antenna on the surface of glass back of the body screen so that mobile phone back panel not only meets beyond fashion degree and the good texture of outward appearance, also meets functional need.
Description
Technical field
The present invention relates to field of mobile phones, particularly relate to a kind of mobile phone back panel with antenna and preparation method thereof.
Background technology
Along with development and the raising of people's living standard of science and technology, the popular requirement to digital products such as mobile phones is increasingly
Height, not only focuses on that it is functional, and the fashion degree and texture to its outward appearance reaches to be close to overcritical stage.Plastic cement and gold
The mobile phone shell on the back belonging to quality has made people create aestheticly tired, thus, the most each big mobile-phone manufacturers begin with glass
Glass is as back of the body screen material.
It will be apparent to one skilled in the art that the mobile phone shell on the back of existing metal quality, sky can be set on mobile phone shell on the back
Line, the mobile phone shell on the back of existing plastic cement quality, it is also possible to by forming metal level at frosting, make the most on the metal layer
Make antenna.But, this area does not also have about employing glass as back of the body screen material, and makes antenna on glass back of the body screen
