Application No.199

Traceability Control for Important Automotive Safety Components



For quality control, important components affecting safety are physically managed by inscribing them with 2-dimensional codes.
For example, when assembling engines, the 2-dimensional code is read and linked to the engine number, and this data is stored in a database for history management.

Application No.200

Reading of 2-dimensional Codes on PCBs



Small, 4 mm x 4 mm 2-dimensional codes (with product number, lot number, production history, inspection history, etc.) are inscribed onto PCBs with direct marking for physical management.

Application No.201

Sheet-feed Control of LCD Glass Substrates with Stringent Quality Controls



Two-dimensional codes containing product information, lot information, serial numbers, etc., are printed directly onto LCD substrates using a laser marker or exposure device, and the 2-dimensional codes are read at each process.

Application No.202

Reading of 2-dimensional Codes on Individual Boxes



Product information, serial numbers, lot data, etc., is written into 2-dimensional codes and printed onto labels that are attached to individual boxes. Because the data cannot be visually confirmed by using only the 2-dimensional codes, the necessary data is also printed in text form.
The 2-dimensional codes are read when shipping the individual boxes, and when the individual boxes are received by the customer.
