Embodiment Construction

[0025] In order to better understand the technical content of the present invention, specific embodiments are given and described as follows in conjunction with the accompanying drawings.

[0026] combine figure 1 , which is a flow chart of the RFID tag-based electronic assembly process product traceability method of the present invention; the present invention is a RFID tag-based electronic assembly process product traceability method, comprising the following steps:

[0027] S1: At the beginning of the production line, when the PCB substrate is on the line, write the batch code of the batch substrate into the unique identification code UID of the RFID tag, and establish a corresponding batch table in the product traceability system database;

[0028] S2: During assembly, when the pallet with the RFID tag arrives at a certain station, the RFID reader on the station first senses the arrival of the tag, and then the station controller on the station sends out a signal , write ...

Abstract

The invention provides a product traceability method of an electronic assembly process based on RFID tags. By attaching RFID electronic tags to a tray carrying an electronic product and batch materials and providing a traceability system, the real-time tracking of each link of the electronic assembly process is achieved. By the set of traceability method, the problems of late information collection and incomplete data in the electronic assembly process be solved, quality-related assembly process information such as personnel, equipment, a production environment and processing parameters in theelectronic assembly process can be traced, a disadvantage that only the composition relationship between materials and components can be recorded in original product traceability is improved, thus the product traceability in the electronic assembly process is more comprehensive, detailed and efficient. The method can be widely applied to product information management and quality management in the electronic assembly industry.

Description

technical field [0001] The invention belongs to the technical field of product traceability in an assembly process, and in particular relates to a product traceability method in an electronic assembly process based on an RFID tag. Background technique [0002] As a necessary part of the electronic product manufacturing industry - electronic assembly is a key step in the formation of electronic equipment products, and it is the last step in determining whether electronic products can finally be qualified. The task of electronic assembly is to assemble various components such as electronic components, chips, PCB boards, connectors and wires into circuit boards (board-level assembly), and then assemble the circuit boards into modules (module assembly), and finally assemble the modules into The process of assembly, inspection and maintenance of the complete machine (complete machine assembly). Generally speaking, the electronic assembly workshop has various automatic assembly a...
