Samsung Electro‑Mechanics adds Broadcom
What happened
- Samsung Electro‑Mechanics announced Broadcom as a new customer for high‑end FC‑BGA AI semiconductor substrates. - The supplier already supports Google, Amazon, and Nvidia with high‑end substrate products. - That win places Samsung substrate supply even more centrally in AI chip packaging and board‑level ecosystems.

Why it matters
Samsung Electro-Mechanics has added Broadcom as a customer for high-end flip-chip ball grid array, or FC-BGA, substrates used in artificial intelligence chips, according to industry reports published April 21. (kedglobal.com) FC-BGA is the thin, high-density board that sits between a chip and the main circuit board, carrying power and data while helping manage heat. Samsung Electro-Mechanics is expected to start supplying Broadcom’s AI accelerators in the second half of 2026, EEWorld reported, citing industry sources. (eeworld.com.cn) The Broadcom win extends a customer list that already included Google, Amazon, Apple and Nvidia for advanced substrate programs, according to multiple Korean and industry reports. Samsung Electro-Mechanics said in August 2024 that it had already begun mass production of high-performance computing server FC-BGA for AMD. (chosun.com, samsungsem.com) Broadcom has become one of the largest suppliers of custom AI chips and networking silicon for hyperscale data centers, which makes its packaging supply chain more important as AI systems get larger. In a September 2025 filing, Chief Executive Hock Tan said Broadcom’s AI semiconductor revenue reached $5.2 billion in the third quarter and was on track for $6.2 billion in the fourth quarter. (sec.gov) Packaging has turned into a bottleneck in AI hardware because faster chips need larger substrates, more layers and tighter manufacturing tolerances. Samsung Electro-Mechanics said in 2024 that server FC-BGA is among the hardest substrate products to mass-produce and that only a small number of companies can make high-end server substrates at scale. (samsungsem.com) Broadcom has been pushing more advanced package designs for custom accelerators as well. On its AI packaging page, the company says its 3.5D XDSiP platform combines 2.5D and 3D chip integration for next-generation custom XPUs, with a smaller package and lower warpage. (broadcom.com) Samsung Electro-Mechanics has been expanding capacity to meet that demand. Chosun reported on April 14 that the company decided to invest $1.2 billion, or about 1.772 trillion won, in Vietnam to increase FC-BGA output for AI servers and high-performance semiconductors. (chosun.com) Investor interest has followed the substrate buildout. Seoul Economic Daily reported on April 15 that Samsung Electro-Mechanics shares rose 35% in six trading days, adding 12 trillion won in market value, as investors bet on AI substrate demand and the Vietnam expansion. (sedaily.com) The Broadcom order adds one more large AI chip designer to a part of the supply chain where customers are trying to lock in capacity years ahead. That leaves Samsung Electro-Mechanics more deeply tied to the boards and packages underneath the biggest AI systems now moving into production. (kedglobal.com, broadcom.com)
