[Samsung Electro-Mechanics plans to spend nearly US$5 billion to expand semiconductor substrate production in South Korea and Vietnam] October 7th, it is reported that Samsung Electro-Mechanics plans to invest nearly US$5 billion in South Korea and Vietnam by 2028 for semiconductor substrate production, further enhancing Vietnam’s position in the production of key components for artificial intelligence servers and high-performance computing. As an electronic components subsidiary of South Korea's Samsung Group, Samsung Electro-Mechanics announced two FC-BGA (flip chip ball grid array) substrate investment plans last week. This product is used in AI servers, robots and smart car chips. One of the investments, worth 4.27 trillion won ($3.2 billion), is for the Sejong factory in South Korea, which is the company's largest investment in a single product to date; the other is 2.51 trillion won ($1.87 billion) for its Vietnamese subsidiary. The company announced in 2022 that it would test FC-BGA substrates in Tai Nguyen Province in northern Vietnam. The expansion of the facility now shows that pilot production results are in line with expectations and the company is ready to enter large-scale production.
