Delta provides the thermal systems required to keep the finished data centre racks cool, while Accton supplies the networking hardware that connects the data centre racks together. The interconnectedness of all the supply chains means that if there are capacity constraints at any single point within the supply chain, it will immediately affect the entire global marketplace.
All market participants, including buyers, investors and systems architects, need to understand how the physical flow of materials plays an important role in the overall supply of technology worldwide.
Executive Q&A: Navigating the Taiwan Hardware Ecosystem
How do restricted advanced packaging processes impact the deployment of AI servers?
The advanced processor does not serve its purpose if it cannot connect to memory. Advanced packaging processes integrate logic and memory chips into a single, high-performance package. Once the packaging suppliers, like TSMC or ASE again, reach their respective production line capacity, global AI server production would stop completely, no matter how many logic chips are printed.
What unique supply chain risks are posed by mature foundry nodes versus leading-edge logic foundries?
Chips that are cutting-edge receive the most media attention. However, the majority of vehicles and industrial equipment rely on older, larger chip designs. UMC’s foundry places emphasis on supporting the mature nodes of the foundry.
The lower margins associated with the older technology have deterred the foundries from building new manufacturing facilities. As a result, whenever demand for the older technology surges, suppliers of industrial products will quickly reach their capacity constraints and cannot increase production quickly enough.
How are Taiwanese ODM firms able to generate revenue beyond simple assembly?
The assembly margin is traditionally very thin at ODM. Many ODMs have started diversifying into other areas to improve their profit levels, such as system integration and direct sales to hyper-scale data centre operators or cloud providers.
Rather than simply providing unbranded boxes filled with assembled parts to large retail brand owners, Taiwanese ODMs, such as Quanta and Wiwynn, are also designing customised server architectures. As a result, the ODM has transitioned from being a replaceable labour partner to an integral engineering partner supporting major data centre operations.
