Photon

Photon makes flexible printed circuit board assemblies, thin, bendable wiring components, used inside the autofocus and optical image-stabilisation mechanisms of smartphone cameras.

It supplies these parts to actuator manufacturers, which are the first-tier suppliers to large Korean electronics companies. Listed on KOSDAQ, Korea's tech-focused small-cap board, the company earns the large majority of its revenue from two product lines: autofocus and optical image-stabilisation assemblies, and focus-zoom assemblies, which together account for nearly all of its sales.
