Pemtron

Pemtron makes precision three-dimensional inspection machines that check for defects during the manufacture of electronics, semiconductors, and rechargeable batteries, catching problems such as misapplied solder or misaligned components on circuit boards before a product is finished.

Its customers are manufacturers in those industries who need automated quality checks built into their production lines. Listed on KOSDAQ, Korea's tech-focused small-cap exchange, the company assembles its inspection systems from high-speed cameras, precision optical lenses, and precision stages, then ships them to customers across Asia, the Americas, and Europe.
