Company History

Our story begins with our parent company COFAN USA, established in 1994 with global sales and manufacturing offices in the United States, Canada, Taiwan, and China. As a specialist in thermal management and PCB/MCPCB design and production, COFAN’s products are used in world-class automotive, aviation, medical, industrial, commercial automation, and LED lighting products around the world.

Flip Chip Opto was created in 2015 as COFAN’s first venture into high power lighting utilizing COFAN’s revolutionary and patented technologies. Recognizing thermal issues as a persistent challenge in producing efficient and reliable UV LEDs, Flip Chip Opto was later rebranded as Violumas, COFAN’s official UV LED division. With revolutionary chip and bonding technologies, we succeeded in providing UV LEDs with the best thermal resistance and thus the highest power and reliability on the market. Leveraging the vast resources of the COFAN USA group, we aim to be an industry leading one-stop-shop for UV LED solutions, including reliable UV LEDs, thermal management solutions, and MCPCBs.
