Abstract

The invention discloses a printed circuit board product coding device and method. The coding is designed by adopting a binary system. The coding method adopts a CNC drilling mode to destroy the electrical conductivity of a copper-clad plate, the part which is not drilled is conductive, the drilled part is not conductive, the on-off signal is tested by an electrical testing device so as to performdecoding, then coded data is displayed through a display screen, the read codes can be connected to an MES management system so as to be transmitted, stored and queried in an Ethernet mode, and product information is enabled to be associated with manufacturing time and process parameters and operators so as to facilitate product tracing. The printed circuit board product coding method solves the problems that the surface of a circuit board is corroded, oxidized and contaminated by a liquid medicine due to process characteristics such as the environmental impact of electroplating and etching processes in the production process of the printed circuit board, thus the traditional method of marking by using barcodes or two-dimensional codes cannot be applied, and the code reading for tracing inautomation production is perplexed.

Description

technical field [0001] The invention relates to the field of traceability of the production process of printed circuit board products, in particular to a coding device and method for printed circuit board products. Background technique [0002] With the development of society and the trend of the manufacturing industry towards Industry 4.0, information factories have higher and higher requirements for product traceability. In the production process of printed boards, each board needs to have a unique code, and ensure that Each workstation can read the code. [0003] The production process of printed circuit boards is limited by the process. The production process of electroplating, wiring, etching and other processes needs to be polished and rinsed with liquid medicine. Traditional barcodes, two-dimensional codes, and RFID cannot adapt to the production environment of the process, especially in copper plating. In the process, a thin layer of copper will be deposited on the ...
