JENOPTIK - VOTAN™ G
Selective Deletion for CIS/CIGS Thin Film Solar Modules with Brushes
Machine Solution
JENOPTIK-VOTAN™ G with brushes
JENOPTIK-VOTAN™ G with brushes
- parallel-selective ablation of the long substrate sides by a one time overpass of rotating brushes
- selective ablation of the short sides by a one time overpass of rotating brushes
- measurement of the reflection and transmission values of the processing area for quality control
Advantages
- no molybdenum damages
- process combinable with the edge ablation process
