Manufacturing method of hardware decorative rear cover with grounding function

Abstract

The invention discloses a manufacturing method of a hardware decorative rear cover with a grounding function, and belongs to the technical field of hardware decorative rear covers. The manufacturing method of the hardware decorative rear cover with the grounding function comprises the following steps: step 1, carrying out pretreatment; step 2, carrying out copper exposure treatment; step 3, carrying out electrophoresis; step 4, performing laser processing; step 5, drying; step 6, assembling, wherein the step 1 comprises a step 11 and a step 12; and step 11, providing a PCB assembly, conductive foam, a TFT screen and a TFT screen hardware rear cover. A part, which can be seen by a user, of a hardware rear cover is made to be black, a part, which needs to be grounded, of an internal structure (a part which cannot be seen by the user) is made to be a conductive area, a laser etching process is adopted, the purpose of laser etching is to remove a surface insulating layer after electrophoresis, and laser etching is carried out on the overall insulating local area according to actual design requirements of a product; and the purpose of grounding with internal structural parts is achieved.

Description

technical field [0001] The invention relates to the technical field of hardware decoration back cover, more specifically, it relates to a method for manufacturing a metal decoration back cover with grounding function. Background technique [0002] Hardware: Traditional hardware products, also known as "small hardware", history has entered the modern industrial society, and the metal-hardware industry has developed rapidly. The hardware industry has played an inestimable role in the development of the national economy, and hardware products have also become industrial manufacturing. An indispensable part of the industry. Instead, it is used as ancillary products, semi-finished products, and tools used in the production process for industrial manufacturing. Only a small part of daily hardware products are tools and consumer goods necessary for people's life, while related products in the category of metal products in manufacturing and general parts in general equipment manufa...

Problems solved by technology

The surface of the SECC material has a galvanized layer, which has a protective effect and also has conductive properties. However, because its color is silvery white, it forms a very sharp contrast with the black contrast of the front touch screen, and it will cause discomfort when viewed by users. comfortability

On the other hand, as an OEM, the dual-screen product is delivered to the OEM. Since the structure of the rear cover is not installed on the car, the outer side of the rear cover is exposed as a whole. The color contrast between the black touch screen and the silver-white rear cover is large. Reduced the grade of dual-screen products
