Taesung

Taesung makes the automated wet-process machinery used on factory lines that manufacture printed circuit boards (PCBs), the flat boards that connect electronic components inside devices.

It supplies these machines to PCB makers at home and abroad, and also provides contract PCB production and consumable process parts such as ceramic brushes. Listed on KOSDAQ, Korea's tech-focused small-cap board, the company is expanding its core PCB equipment business into machinery for glass substrate fabrication and for producing copper foil, a key material in rechargeable batteries.
