Electronics giant Samsung has approved the spending of some 850 million USD for its unit in Vietnam to manufacture flip-chip ball grid arrays (FC-BGA), according to KBS News. FC-BGA is a highly-integrated package board used to connect a high-integration semiconductor chip to a main board. The company will spend the investment in phases until 2023 to build a new FC-BGA production line. Under the plan, the Vietnamese subsidiary will focus on producing FC-BGA while Samsung's factories in the Republic of Korea will specialise in technology development and high-end products./.
