CO2 Laser Marker for Substrate with Readable Backside Code for Semiconductor Manufacturing

A laser marker that reads the two-dimensional code printed on the back and prints it on the front.

In the semiconductor manufacturing industry, wafer traceability management is crucial. In particular, individual identification and tracking during the manufacturing process are essential for quality control and yield improvement. Incorrect identification or tracking errors of wafers can lead to the occurrence of defective products or delays in the process. Our CO2 laser marker for readable substrates on the back side can be integrated into the SMT assembly line, achieving substrate printing without stopping the line (on-the-fly printing). This contributes to efficiency and quality improvement in process management while maintaining tact time. Additionally, as an optional feature, it supports the processing of "reading the two-dimensional code printed on the back and printing it on the front." This automates the data linking after the substrate is flipped, enabling advanced traceability management that integrates both sides. 【Usage Scenarios】 Versatile code printing: Support for QR codes, DataMatrix, Micro QR codes, barcodes, etc. 【Benefits of Implementation】 Prevention of misidentification: By printing the front side based on the individual information on the back, it eliminates mistakes in substrate mix-ups. Strengthening traceability: Achieves accurate individual tracking management in the assembly process.
