Mount ID Tags (Data Carriers) to dedicated cassettes that contain (several dozen) disks. Write product information, lot information, work instructions for each process, process completion flags, and instructions for the next process to the ID Tags. In each process, read the information from the ID Tags using R/W Heads mounted to the machinery, and perform processing or inspection based on this information. For inspection processes, write the inspection results (i.e., OK or NG) to the ID Tags.

At the end of each process, write instructions relating to process completion flags and the next process as appropriate.

At the final process, read all the information in the ID Tags, and store it in the host for lot control.

Know-How

ID Tags are mounted to special cassettes, and the necessary information is written to the ID Tags. Due to their heat resistance (up to 180 degrees centigrade), the same ID Tags can be used for all facilities, including high-heat locations such as those for drying processes.

Benefits

• Using a highly environment-resistant RFID System enables stable monitoring of lot information and process information, allowing the creation of accurate, error-free automated lines. In particular, the RFID System contributes greatly to increasing yield rates, which, in a climate of intense competition to reduce costs, is an important factor in ensuring profits.
• Writing history information for each process ensures traceability within the process without placing an undue burden on the host. This leads to improvement in quality control (contributing to ISO 9000).
