Frequently Asked Questions

FAQ of Ooitech Solar Cell No-Destructive Laser Cutting Machine.

Ooitech NDC adopted the thermal laser separation technology (TLS-Dicing), which called “No-Destructive Cutting” in domestic China. And have two integrated long lifetime and low-maintenance fiber laser sources, to cut solar cells without damages.
Ooitech NDC Cutting Machine, is a WATER-FREE spray cooling laser NDC machine, which using the latest solar cell cutting technology with lower power, lower temperature, and WATER-FREE dicing. The cutting cell has higher bending strength, better electrical performance, and NO secondary pollution or WATER-CAUSED micro-BROKEN after cutting. And the Breakage rate less than 0.03% in mass production.
NDC machine already working in Longi solar, Jinko solar, Renesola Solar, Yingli Solar, Suntech, Chint, etc factory and overseas like Australia, India, Turkey...
Ooitech NDC machine could install and maintain by remote internet, or get services from our agents in some countries. And we are sincerely looking for agent distributors from all countries.
