Market Growth Factors

1) Performance-driven packaging for 5G, AI, and edge workloads

The rapid rise in 5G devices, AI accelerators, and high-bandwidth computing is driving up the demand for signal integrity, low latency, and power efficiency in advanced packaging. Flip-chip BGA (FC BGA) substrates are leading the way by shortening interconnect paths and enhancing electrical performance, making them the most popular choice. This technology allows for quicker data transfer, improved thermal management, and denser integration—essential for smartphones, high-performance computing, networking equipment, and wearables. As manufacturers strive for sleeker designs and greater computing power, investments in multilayer, fine-line substrates are increasing across fabrication plants and OSATs, further solidifying FC BGA’s market share and opening new premium opportunities.

2) Miniaturization and integration trends across consumer, auto, and telecom.
Consumers are looking for thinner devices that boast longer battery life and a wealth of features like AR/VR and HD displays, which is pushing substrates to fit more components into smaller spaces. Advanced IC substrates facilitate high-density interconnects, multilayer stacking, and dependable power delivery without sacrificing performance—perfect for consumer electronics, which is the largest application, and the increasingly complex automotive electronics found in ADAS and EV platforms. In the IT and telecom sectors, compact radios and baseband units gain from fine-pitch routing and effective thermal management. These trends toward miniaturization and integration are steadily increasing the value of each device, promoting the adoption of premium substrates across various end markets.

3) Cloud and data-centre scale-out boosting thermal and reliability needs.
The global cloud landscape is rapidly evolving, with big-data workloads driving an increase in server numbers and compute density. As a result, thermal hotspots and reliability issues are becoming significant challenges. To keep systems running smoothly and efficiently, we need substrates that excel in heat dissipation, controlled impedance, and low loss tangents. Cutting-edge materials and techniques, like precision lithography and laser drilling, are enhancing consistency and scalability for complex, high-layer builds. As hyperscale’s focus on boosting energy efficiency and throughput, substrate suppliers who meet these demands are seeing a steady rise in demand, particularly as the Asia Pacific region ramps up its supply chain capabilities to add capacity in a timely manner.
