Background
With the aggravation of market competition and the acceleration of the informatization process of the manufacturing industry, the market puts higher requirements on the management and control of product quality and product production. The products in the discrete manufacturing industry have complex structures and a plurality of uncertain factors in the production process, and are difficult to acquire production data and diagnose quality problems. The PCB (Printed Circuit Board) is widely applied to various electronic products, is an important electronic connecting piece, and the quality of the PCB concerns the quality of the whole electronic product, and for better management and control of the product quality, relevant production information needs to be recorded, so that the whole-process tracing and quality management and control of the electronic product are facilitated.
At present, in the PCB printing process, a series of procedures such as coating ink, copper deposition electroplating, dry film and solder resist ink can be experienced, and marks such as fonts or two-dimensional codes on the PCB board are easily covered and fail, so that some PCB printing enterprises adopt the hole array codes made inside to mark the PCB board in a punching manner so as to record production information in the printing process. However, this method can only trace back the printing process of the PCB board since the raw material label of the PCB is covered during the printing process and does not trace back the supplier before the printing of the PCB and the production process of the raw material of the PCB. In addition, supply chain manufacturers involved in manufacturing the PCB are numerous, production is easy to be disordered, and the product query speed is low or even the product source cannot be traced.
