X Link® off-line
X Link® enables fast, automated, non-destructive and accurate evaluation of the level of EVA or polyolefin cross-linking in PV module encapsulation processes.
In solar modules, the ethylene vinyl acetate (EVA) or polyolefin encapsulation protects the sensitive solar cells from the environment. In consequence the degree of intermolecular cross-linking of EVA or polyolefin is decisive for the long-term stability and performance of a module. Cross-linking is achieved by thermally curing the polymers during the lamination process.
The X Link® system enables fast, automated, non-destructive and accurate evaluation of the level of EVA or polyolefin cross-linking immediately after lamination. It can be integrated into any solar module production site, offering a flexible platform for encapsulation quality control ranging from single point sampling to full module mapping.
The stand-alone version is designed for lab applications, manual product sampling, areal mappings, R&D labs and pilot lines, ready to test full-size production-type modules with or without frames. High-resolution spatial mappings of the cross-linking degree and statistical evaluation can be performed.
Furthermore, the manual off-line version allows multiple-point measurements on laminates and out-of-production modules, and modules from the field. This setup is a highly useful quality control tool for incoming goods inspection for EPCs, certifiers and consultants.

Features
X Link® in-line version
The in-line version is designed line integration into the manufacturing automation system. Here, multiple head configurations are available so that several fixed positions can be measured on every sample in a fully automated way.
X Cal calibration device
High accuracy of X Link® systems is indispensable for process control and quality management in solar module production. It is recommended to calibrate X Link® after its delivery or moving as well as once a year to fulfill the requirements of quality auditors. To guarantee X Link's high precision, LayTec offers X Cal - a set of high precision equipment for on-site calibration of X Link® systems.
