DISCO Laser Saws Sales Exceed 200

DISCO Corporation (Headquarters: Ota-ku, Tokyo; President: Kazuma Sekiya) has announced that the sales of the laser saws launched in 2002 reached 200 in January 2010. This record was achieved four months ahead of the May 2010 target established in the planning at the beginning of this year.

As background to this early achievement, DISCO's unique stealth dicing technology for high-intensity LEDs has been highly evaluated by major LED manufacturers all over the world. Accordingly, the DFL7340 laser saw having this technology has been shipping at a pace greatly exceeding the estimate, and the laser saws for Low-k film grooving, which is commonly used in high-speed devices currently, has also sold steadily.

DFL7340 DISCO Laser Saw Sales for LED


So far DISCO's business consists of three segments: dicing saws, backgrinders, and precision processing tools (consumables). The sales results in 2009 indicate that the laser saw business, which has been steadily developing, has now grown to a new strength for DISCO supported by strong LED demand.
