EVG620 HBL Gen II Fully Automated Mask Alignment System for HB-LEDs by EV Group

The EVG620 HBL is a dedicated, fully automated mask alignment system for high volume manufacturing of High-Brightness LEDs (HB-LEDs), compound semiconductors and power electronics. Based on the highly successful and field-proven EVG620, the HBL-version - in its second generation - is optimized for lowest cost-of-ownership and highest yield in LED and compound semiconductor manufacturing. Processing of up to 165 wafers per hour with highest alignment accuracy. Designed to handle bowed, warped and transparent substrates up to 150 mm, as being common in HB-LED, RF and power devices or surface acoustic wave filters. These features make the EVG620 HBL the perfect solution for high volume manufacturing of HB-LEDs and compound semiconductors.


Dedicated mask alignment system for HB-LEDs

  • Wafer sizes up to 150 mm
  • Up to 220 wafers per hour in first print mode
