Recently, Samsung Electro-Mechanics announced that by 2026, the sales share of its high-end Flip Chip Ball Grid Array (FCBGA) substrates for server and artificial intelligence will exceed 50%.

FCBGA is an integrated circuit (IC) packaging technology，which involves flipping the chip and connecting it to the packaging substrate, then using spherical solder bumps to attach the package to the substrate.

It is mainly used in the packaging of high-density, high-speed, multi-functional large-scale IC chips, offering advantages such as high integration, small size, high performance, and low power consumption.

After a prolonged period of inventory cutting, the balance between semiconductor supply and demand sides has improved, with market demand gradually recovering.

The strong demand in fields such as high-speed network, server, smart driving, and optical module has continuously energized the development of high-multilayer high-speed boards and advanced HDI boards, which in turn is gradually boosting the prosperity of the packaging substrate industry.

As one of the main packaging methods for core electronic components like PC central processing unit, memory, and graphics processor, FCBGA boasts significant market potential in the development of 5G communications, artificial intelligence, virtual reality, and other fields.

Globally, IDM companies such as Micron, Infineon, and NXP have conducted extensive research and development in the FCBGA packaging field, while specialized packaging and testing companies like ASE Group, JCET, and Amkor have also developed various FCBGA technologies.

It is reported that numerous major international semiconductor companies, including Intel, Qualcomm, NVIDIA, AMD, and Samsung, are utilizing FCBGA technology.

Intel is one of the pioneers of FCBGA technology, first applying it to processors in 1997, while Apple is a loyal adopter of FCBGA technology, having used it in its processors from an early stage.

Data indicates that the global FCBGA packaging technology market will continue to grow rapidly in the coming years, with the market size expected to exceed USD 20 billion by 2026.

In face of such a highly potential opportunities, an increasingly more companies are channeling more efforts in developing FCBGA packaging technology, continuously facilitating its innovation and upgrade, and Chinese companies are also a part of this competition.

Currently, main companies engaging in FCBGA packaging substrates business in China include Fastprint, SCC, and FHEC (Forehope-elec), etc, which have disclosed their current progresses referring to FCBGA research and development.

Besides, Strongteam, a real estate company attempting to enter the semiconductor field, has set its sight on the FCBGA sector.

Fastprint disclosed that its low-layer FCBGA packaging substrates are currently in the small-batch delivery stage, with primary applications in the automotive and AI sectors.

SCC stated that it already has the capability of mass producing FCBGA packaging substrates with 16 layers and less, and the capability of sample manufacturing products with more than 16 layers.

The production line validation, sample delivery, and certification processes for various product levels have proceeded smoothly on track. Strongteam is actively transitioning into the semiconductor field and plans to invest in high-end FCBGA IC substrate enterprises.
