The X Link system enables fast and accurate evaluation of the level of EVA cross-linking after
lamination. It can be integrated into any solar module production line, and offers 100% co -
verage for process control and quality assurance:
- non-destructive method
- testing time of seconds
- in-line measurement capability
- module mapping option
- data output in “% gel content”
- multi-point measurement capability
- sturdy design for industrial application
LayTec X Link measurement systems predict the long-term stability of solar modules by evaluating the level of
cross-linking in EVA solar module encapsulation: within seconds, non-destructively and accurately. It enables in-line
monitoring of the solar module lamination process. Customized systems are available.
- no more scrapping of laminates
- easy integration into existing production lines
- feedback control of lamination process
- gapless quality assurance
Speciﬁcations are subject to further technical development
and may differ from those given in the datasheet.

The measurement requires the module to have a temperature of 80 °C or higher. Ideally, it is
installed immediately after the lamination process.
Optional heating stages are available for measurements further along the production line
or for off-line measurements. During the measurement, physical contact to the back sheet
The in-line version is based on highly robust industrial grade embedded system protocols
and can be directly connected to production systems and SPC databases by a large variety of
protocols along with clear user visualization for quick on-line inspection.
