Kostecsys

Kostecsys develops packaging and thermal-management components for power semiconductors, the chips that control and convert electrical power in demanding applications.

Its products are aimed at makers of power semiconductor modules and high-performance computing systems that need to handle high heat and high power density. The company is focused on a shift from traditional wire-bonding interconnects to metal-block-based connections, such as copper blocks and copper clips, which offer lower electrical resistance and better heat dissipation. It is listed on KOSDAQ, South Korea's tech-focused small-cap exchange.
