Meyer Burger and LayTec have collaborated to produce the world’s first fully integrated EVA cross-linking metrology solution for PV module production lines.
Problem
Until recently, the guaranteed life-time and long term stability of a module was calculated by carrying out destructive off-line tests on less than 1% of the modules and then statistically extrapolating the results for end-users.

Solution
The integrated EVA cross-linking metrology system is a stream-lined solution for process optimization and yield enhancement in module manufacturing lines. The measurement heads are directly integrated into the cooling press of Meyer Burger laminators. They facilitate closed loop process control and 100% quality assurance of EVA lamination. The system fully replaces slow, error-prone and costly off-line analysis methods. By integrating original OEM technology into the non-destructive lamination process control, module manufacturers are able to undisputedly prove the long-term stability of 100% of their module production. Based on in-line and off-line X Link technology, certifiers can now refer to a non-destructive and repeatable standard method for line and fab certifications.
Applications
EVA lamination of PV modules.
Platform
Upgrade possible for NG and JT 3S Modultec laminators.
Availability
July 2013 onwards.
