Reliable Reading of DPM Codes on moving PCB in Processing

Fixed mount barcode scanner

In the electronic PCB industry, the process of reading codes is a crucial step in ensuring the accuracy and efficiency of the manufacturing process. This step typically involves the use of code reading equipment, such as barcode scanners or fixed code readers, to capture and interpret the unique codes and identification markings on the PCB boards.

The code reading process can occur at different stages of the PCB manufacturing process, depending on the specific requirements and regulations of the industry. For example, it may take place during the incoming inspection of raw materials, at the end of the production line to check for defects and errors, or during the packaging and labeling of the finished products.

Regardless of the stage, the goal of the code reading process is to accurately identify and track each PCB board as it moves through the production line, ensuring the quality and integrity of the final product. By using state-of-the-art code reading technology, the electronic PCB industry can stay ahead of the competition and deliver high-quality products to their customers.

PCB manufacturer came to the Heroje office requesting a solution that could stably and accurately read QR codes on moving PCBs.


In this project, the code reader needs to accurately capture the QR code and read it stably at the servo motor rotation speed of 5000 rpm. The QR code is laser marked on the copper plate, and the QR code size is 6x6mm. All these factors are combined Together, it adds a certain degree of difficulty to this project.
