SEOUL – South Korea's Interflex will invest approximately $18 million in its Vietnamese subsidiary, Korea Circuit Vina, as part of an ongoing effort to expand printed circuit board manufacturing capacity in Vietnam.

The investment will increase Interflex's ownership stake in Korea Circuit Vina from 83.5% to 89.3%. Located in Vinh Phuc province, the facility serves as a PCB manufacturing base supporting the Korea Circuit Group's regional production strategy.

Interflex, a major supplier of flexible printed circuit boards, operates manufacturing facilities in South Korea, China and Vietnam. The company said the latest investment is intended to strengthen overseas manufacturing operations and enhance competitiveness in global electronics markets.

The move follows a previous $28 million capital injection into Korea Circuit Vina in 2025 and reflects continued investment in Vietnam as a growing electronics manufacturing hub.
