Application No.206

Reading 2-dimensional Codes on Metallic Parts



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.207

Managing PCBs with 2-dimensional Codes



PCBs can be physically managed by direct marking them with a small (approximately 4 mm x 4 mm) 2-dimensional code ( with model number, lot number, production history, inspection data, etc.).

Application No.208

Sheet-feed Control for Liquid Crystal Glass Substrates



Two-dimensional codes containing product information, lot information, serial numbers, etc., are printed directly onto LCD substrates using an exposure device or laser marker, and the 2-dimensional codes are read at each process.
In locations where people are involved, a handheld reader is used.

Application No.209

Random Sampling of Electronic Components in a Clean Room



Two-dimensional codes containing product information, such as serial numbers and feature values, are printed onto components by direct marking.
This data is read during inspections, and saved onto an SD card together with the inspection results.
When the work is completed, the saved log is transferred to a database.
