Quality control

Each batch of products will be inspected, our production process has a strict quality control system, from raw materials to the final inspection, each production link has self-inspection and re-inspection, and IPQC inspection. We also provide samples for customers to re-inspection, if the customer has a designated inspection organisation, we also support third party inspection and issue inspection reports.

Packaging and Storage

Copper Indium Gallium Selenide sputtering targets are usually packed in double vacuum bags.
Copper Indium Gallium Selenide sputtering targets should be stored in a dry, cool, well-ventilated environment protected from light, in sealed packages to prevent moisture and oxidation, while avoiding contact with corrosive substances such as acids and alkalis, and away from high temperatures and possible mechanical collision, in order to maintain the integrity and chemical stability of the target.
