Overview

SEC, listed on KOSDAQ (Korea's tech and small-cap exchange), makes inspection equipment that uses X-rays and electron beams to detect defects inside products without damaging them, a technique known as non-destructive testing.

Its systems serve semiconductor and battery manufacturers, defense contractors inspecting large structures such as rocket propellants and warheads, and research laboratories in materials science, biotech, and chemistry. The majority of its revenue comes from X-ray inspection systems for the semiconductor and battery industries.
