Reading LED packages/ceramics

As electronic components become smaller and more densely packed, traceability management for LED packages and ceramic substrates is becoming increasingly important. However, the 2D codes printed in limited spaces are becoming microscopic. Laser engraving on white ceramic materials, in particular, tends to have low contrast, causing frequent reading errors with conventional code readers. This leads to production line stoppages and reduced yield rates.

The KEYENCE AI-powered code reader, SR-X Series, solves these challenges of reading challenging codes. The SR-X Series utilizes proprietary image processing algorithms and a variety of lighting technologies to instantly and stably read even microscopic codes with cell sizes as small as 10 μm, or low-contrast codes with faded or uneven printing, on fast-moving workpieces. Furthermore, the AI automatically generates optimal settings from the captured images, allowing even users without specialized knowledge to easily achieve the best reading performance.

By eliminating minor stoppages caused by reading failures and building a reliable traceability system, this solution significantly contributes to enhancing quality control and improving productivity in electronic component manufacturing.
