All the pastes we sell have to be qualified with RoHS requirements through SGS lab. We avoid all the listed forbidden materials while we start to research and develop our paste. The concept of environmental protection has been applied to our product development continuously. 

 

We have excellent product certification capability. This reliable quality control system is involved during the developing stage. Concerning the product quality, we also did tests for preservations during storage and transportation. Further to ensure durability and validity, we produce the cell and module by using our paste, which will be tested by Thermo Cycle, Damp Head, and UV Exposure according to the law IEC 61215.
