A traceable circuit board production method

Abstract

The invention relates to the technical field of circuit board production, in particular to a traceable circuit board production method. By first setting the production process of the circuit board, a unique code corresponding to the circuit board is formed, and a two-dimensional code is generated by a two-dimensional code generator. Script, and then process and manufacture circuit boards according to the set process flow. Each equipment machine records the actual processing parameters corresponding to the coded circuit board during process production, and then the information department can collect the data of each equipment machine through Ethernet. The processing information forms traceable information, which is inserted into the QR code script as a hyperlink to realize the traceability of the circuit board. Through-resistance soldering process, the subsequent circuit board graphics transfer exposure process can only be performed after exposing the two-dimensional code pattern on the circuit board. Through one transfer and two exposure operations, it is ensured that the QR code pattern can be obtained and traceable by scanning the code. Circuit board production information to achieve the purpose of circuit board traceability.

Description

technical field [0001] The invention relates to the technical field of circuit board production, in particular to a traceable circuit board production method. Background technique [0002] With the rapid development of electronic communication, in order to meet the needs of traceability of electronic equipment, the cycle under the traditional human intervention, that is, the text screen printing cycle, has a large cycle variability, chaotic batch control, and low cycle reliability. And so on a series of questions. In addition, the customer terminal cannot lock the PCB cycle, material number, processing equipment, processing parameters and other information. Once the quality of the PCB is abnormal, the scope of influence cannot be effectively and accurately locked, and it is difficult to trace the batches of PCBs with quality problems, resulting in large The isolation of batch products and the analysis of the causes of quality abnormalities are hindered, resulting in the fai...
