As of 9:20 a.m. on the day, Samsung Electro-Mechanics was trading at 630,000 won, up 46,000 won (7.88%) from the previous session on the Korea Exchange.

According to Bloomberg News on the previous day, Samsung Electro-Mechanics is understood to be planning to invest $1.2 billion (about 1.8 trillion won) in its Vietnam manufacturing subsidiary to expand production capacity for flip-chip ball grid array (FC-BGA), a high value-added substrate.

Samsung Electro-Mechanics is said to have received an investment registration certificate related to FC-BGA production, a high value-added semiconductor substrate, from the Vietnam Foreign Investment Agency.

FC-BGA is a high-density package substrate in which a semiconductor chip is flipped and mounted on a substrate and then connected with fine metal balls. As demand has surged recently, supply shortages have continued.

Samsung Electro-Mechanics has been producing FC-BGA in Vietnam since 2024.
