Embodiment Construction

[0024] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0025] Such as figure 1 As shown, the traceability identification code of the whole process of PCB manufacturing is formed by drilling holes on the PCB. The identification code includes a mark area, a data area, and a verification area. The mark area is used to identify the row and column marks, and the data area is used to verify PCB board code, the check area is used to cooperate with the data area for error correction and identification error judgment.

[0026] The data area includes 120 data holes, which are divided into 4 rows, with 30 holes in each row, and each data hole can be punched with one data hole.

[0027] The verification area is located on the right side of the data area, including 16 verification holes, divided into 4 rows...

Abstract

The invention discloses a PCB manufacturing full-process tracing identification code, a coding method and application. An identification code is formed on a material in a drilling mode, the identification code comprises a mark area, a data area and a verification area; the mark area is used for identifying row and column marks, the data area is used for encoding a PCB, and the verification area isused for conducting error correction and identification error judgment in cooperation with the data area. According to the identification code provided by the invention, the problem that a traditional bar code or a two-dimensional code cannot be read due to damage when the surface of a material is damaged and covered in the production and processing process of the material is solved in a manner of drilling a through hole in the material by adopting a numerical control drilling machine, and the identification code is firstly applied to a whole-process tracing project in the PCB manufacturing industry.

Description

technical field [0001] The invention belongs to the field of traceability of PCB manufacturing, and specifically relates to a traceability identification code, an encoding method and an application of the whole process of PCB manufacturing. Background technique [0002] During the production and processing of materials, the surface of the material as an information carrier has to be damaged or covered by the production process (such as corrosion, electroplating, grinding, spraying, pressing, etc.) during the production process, so that the material attached to the surface of the material Information cannot be read effectively. For example, the two-dimensional codes and barcodes we use now are easily damaged by wear and tear during the production process, making it impossible to read the information recorded on them. Contents of the invention [0003] The identification code provided by the invention solves the problem that the traditional bar code or two-dimensional code ...
