OKI Electric Industry Co., Ltd. (TOKYO: 6703) launches comprehensive Electronics Manufacturing Services (EMS) for AI server equipment, marking a strategic expansion into advanced data center infrastructure manufacturing. The service, introduced on March 25, 2026, is designed to support AI server manufacturers with end-to-end capabilities spanning design, component procurement, PCB assembly, system integration, testing, and reworking.
The launch comes as demand for AI infrastructure continues to surge, driven by the rapid adoption of generative AI applications. AI workloads require significantly higher computing power than traditional cloud services, leading to increased deployment of AI servers equipped with high-performance components such as GPUs and high-bandwidth memory (HBM). This shift has intensified manufacturing challenges, particularly in areas such as thermal management, precision assembly, and quality control.
OKI’s EMS offering addresses these complexities through its proprietary high heat dissipation technology embedded within large-size multi-layer printed circuit boards (PCBs). The company’s copper coin-based design enables efficient heat management for densely packed AI semiconductors, while supporting high-speed, high-capacity data transmission essential for modern AI data centers.
Production of AI server equipment presents several technical hurdles, including maintaining high component placement accuracy, mitigating thermal expansion issues during high-temperature processing, and detecting solder defects that are difficult to identify through conventional inspection methods. Increasing traceability requirements and the complexity of reworking expensive components have also contributed to lower yields and longer production cycles across the industry.
To overcome these challenges, OKI is leveraging its expertise in semiconductor testing equipment and communications infrastructure manufacturing. The company integrates simulation-driven PCB design, high-speed X-ray solder inspection, and automated functional testing to enhance quality and efficiency. These capabilities are aimed at improving production yields and reducing lead times for AI server equipment.
A notable feature of the service is its advanced reworking capability. Using proprietary tools combined with skilled technician intervention, OKI can repair complex AI semiconductors with high pin counts, even after assembly. This approach enables manufacturers to reduce waste, lower failure-related costs, and improve operational efficiency.
With this initiative, OKI aims to achieve sales of JPY 1 billion in fiscal year 2026, positioning itself as a key manufacturing partner in the rapidly expanding AI infrastructure ecosystem.
