As part of the growing market of the LED segment and the on going demand to lower the cost of production per unit (CoO), ADT has responded with a dual spindle system model 7900 Duo that double the productivity while maintaining the same current production floor space.
The 7900 Duo system provides a perfect solution for applications that require a long cut cycle time such as image sensors and saw devices.
Further to the automatic vision and easy New User Interface (NUI), ADT is offering a unique feature for processing and programming of broken wafers.
