Scanning codes on PCBs with misaligned printing

Traceability management is essential on manufacturing lines for electronic components and printed circuit boards (PCBs). However, a common problem is that 2D codes such as DataMatrix printed on the silk screen of a board can become misaligned from their original position due to timing shifts during transport, leading to frequent reading errors. With conventional code readers, this slight print misalignment causes unstable reading, resulting in production line stoppages and manual recovery work, which significantly hinders productivity improvements.

KEYENCE's SR-X Series AI-powered code reader solves these on-site challenges. Its newly developed powerful reading algorithm and excellent position misalignment correction function enable it to instantly recognize the pattern and achieve stable reading even if the code's print position is off. This allows for smooth and reliable traceability management even in PCB manufacturing processes that previously suffered from reading errors, contributing to a significant improvement in production efficiency and a higher level of quality control.
