Embodiment Construction

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0025] An embodiment of the present invention provides a method for making an identification code, which is applied to form an identification code on a camera module. The identification code is an identity code of the camera module and is used for product tracking and tracing. Wherein, the identification code may be a two-dimensional code, or a barcode, etc., which is not limited in the present invention.

[0026] like figure 1 As shown, the process flow of t...

Abstract

The invention provides a method for making an identification code, a camera module and an electronic device, comprising: forming an ink layer and an ink alignment mark on the part of the identification code to be produced, the ink layer and the ink alignment mark are located on the same layer, And the distance between the ink alignment mark and the ink layer is a fixed distance; the position of the ink layer is determined according to the ink alignment mark, and an identification code pattern is formed on the ink layer. The present invention forms the ink alignment mark while forming the ink layer, and the distance between the ink alignment mark and the ink layer is a fixed distance, that is to say, when the position of the ink layer deviates, the position of the ink alignment mark The offset of the corresponding distance will also occur. Therefore, the position of the ink layer can still be accurately determined according to the ink alignment mark, so that the deviation of the identification code can not be caused, and the alignment accuracy is high.

Description

technical field [0001] The invention relates to the technical field of camera modules, and more specifically, to a method for making an identification code, a camera module and electronic equipment. Background technique [0002] At present, more and more camera modules require identification codes (such as QR codes) to facilitate product tracking and tracing. In the prior art, when making the identification code, a layer of ink is screen-printed on the ink area on the metal layer of the main circuit board of the camera module, that is, PCB (Printed Circuit Board, flexible circuit board), and then according to the metal on the metal layer. The position mark determines the position of the ink area, and finally the identification code pattern is made on the ink of the ink area. [0003] However, since the screen printed ink often deviates from the ink area when printing ink, and the position of the metal alignment mark is fixed, if the position of the ink is still determined a...
