microDICE - Wafer Dicing System using TLS-Dicing

Compared to traditional separation technologies, such as saw dicing and laser ablation, TLS-Dicing enables a clean process, micro-crack-free edges, and higher resulting bending strength. Capable of dicing speeds up to 300mm per second, the microDICE™ system provides up to a 10X increase in process throughput compared to traditional dicing systems.
