Problems solved by technology

[0003] Generally, the traceability QR code will be laser engraved on the copper surface of the circuit board. However, the circuit board needs to go through many processes during the production process. These processes include mechanical processing and chemical treatment. After these processes, the circuit The traceable QR code engraved by laser on the board is easy to be ground and covered, which will greatly affect the success rate of later code reading and even make the traceable QR code unreadable

Embodiment Construction

[0025] The features of the present invention and other related features are described in further detail below through the examples, so as to facilitate the understanding of those skilled in the industry:

[0026] like Figure 1 to Figure 3 As shown, a method for making a two-dimensional code for traceability of a circuit board includes the following steps:

[0027] Step 1: provide a circuit board blank 1 with a code area 2 reserved on the circuit board blank 1;

[0028] Step 2: Virtually divide a rectangular array consisting of several square units 3 of the same size within the scope of the code area 2, and the adjacent square units 3 share a side;

[0029] Step 3: Drill a circular through hole 4 through the circuit board blank 1 in the center of some of the square cells 3 according to the preset traceability information, and all the square cells 3 with the circular through hole 4 in the rectangular array are drilled Together with the square unit 3 without the circular throu...

Abstract

The invention discloses a manufacturing method of a circuit board traceability two-dimensional code, which comprises the following steps of: 1, providing a circuit board blank, and reserving a code area on the circuit board blank; 2, virtually dividing a rectangular array formed by a plurality of square units with the same size in a code area range, wherein the adjacent square units share the same edge; and step 3, drilling circular through holes penetrating through the circuit board blank in the centers of part of the square units according to preset traceability information, wherein all the square units drilled with the circular through holes and all the square units without the circular through holes in the rectangular array jointly form a traceability two-dimensional code used for bearing the traceability information of the circuit board.

Description

technical field [0001] The invention relates to a method for making a circuit board traceability two-dimensional code. Background technique [0002] At present, in order to better track each circuit board, a traceability QR code is often printed on the circuit board during the production process of the circuit board. The traceability QR code carries the relevant information of the circuit board. Information about the board can be obtained. [0003] Generally, the traceability QR code will be engraved on the copper surface of the circuit board by laser. However, the circuit board needs to undergo many processes during the production process. These processes include mechanical processing and chemical treatment. After these processes are processed, the circuit The traceability QR code engraved by laser on the board is prone to be flattened and covered, which will greatly affect the success rate of later code reading and even cause the traceability QR code to be unreadable. ...
