Traceability system suitable for PCB manufacturing

Abstract

A traceability system suitable for PCB manufacturing comprises a plurality of two-dimensional code makers disposed at a starting end of a production line, before a laminating step, after the laminating step and before the step of molding and shipment, two-dimensional code readers disposed at equipment feeding ports of different production steps, and a traceability system database. The two-dimensional code makers and the two-dimensional code readers are in communication connection with the traceability system database. Each two-dimensional code maker stores information on a two-dimensional code made on a PCB into the traceability system database. When the PCB enters production steps after the corresponding two-dimensional code maker, the two-dimensional code reader of each production step reads out the independent two-dimensional code on the PCB, and stores the two-dimensional code, code reader number and readout time into the traceability system database. Before the step of molding and shipment, the two-dimensional code is made on the surface of the PCB through a two-dimensional code ink-jet printer or a two-dimensional code laser coding machine. The entire production process of the PCB can be traced more accurately and conveniently.

Description

technical field [0001] The invention relates to the technical field of PCB manufacturing, in particular to a traceability system suitable for PCB manufacturing. Background technique [0002] Traceability of the cause of product problems is a serious challenge for manufacturers in every industry, from automotive to aerospace, from medical to food. In an era of globalization, businesses pursue relationship management to maximize customer satisfaction. Consumer and environmental regulations are becoming stricter, making traceability even more necessary. More than ever, manufacturers are looking to maximize production capacity and reduce costs. To achieve this goal, every step in the entire manufacturing process must be monitored and complete historical records kept. Issues affecting product quality must be quickly identified and corrected to prevent defective products from continuing down the production line, with the ultimate goal of achieving zero product returns as much ...
