EVG560 HBL Fully Automated Wafer Bonding System for HB-LEDs by EV Group

The EVG560 HBL is a dedicated, fully automated wafer bonding system for High-Brightness LED (HB-LED) manufacturing. The flexible tool supports metal, adhesive and fusion bonds of various substrate types. Cassette-to-cassette operation, multisubstrate bonding capability and a modular design with up to four swap-in process modules make the EVG560 HBL the perfect solution for high-volume HB-LED manufacturing. EVG's field proven wafer bonding technology, as well as our unique approach to low temperature metal wafer bonding, results in highest throughput and yields.
