Company and Industry Summary Company: Ta Liang Key Points - **Upgrade of Communication Protocol**: The upcoming NVIDIA Rubin platform will feature an upgraded communication protocol between GPU and NVSwitch, utilizing 224GSerDes on PCB with a significant signal frequency increase to a maximum of 56GHz, compared to 28GHz on the Blackwell platform. This upgrade indicates that even minor via stubs can lead to severe signal degradation, establishing a ±2mil stub height as the threshold for signal transmission quality. Accurate closed-loop measurement is deemed crucial for manufacturing quality control [1][1][1] - **StubMapper Device**: Ta Liang has developed a proprietary device called StubMapper, which enables ±2mil depth measurement to guide subsequent back-drilling processes executed by Ta Liang's 6-axis CCD drilling machine. StubMapper can provide profile measurement data back to the back-drilling machine, enhancing precision in manufacturing [1][1][1] - **Increased Demand for Back-Drilling**: There has been a surge in industry demand for back-drilling to meet the requirements of high-end AI PCBs, resulting in an extension of PCB equipment delivery cycles from 1.5 months to over 3 months. This demand has led Ta Liang to consider outsourcing more low-end drilling tool production to focus on high-end tool manufacturing [2][2][2] - **Production Capacity and Future Plans**: Ta Liang's current monthly production capacity is approximately 300 sets of drilling tools. The company plans to enhance the throughput of StubMapper by introducing a four-probe version, with mass production scheduled for March 2026, and initial customer reservations already in place [2][2][2] - **Semiconductor Equipment Division**: Ta Liang also operates a semiconductor equipment division focused on measurement and automated optical inspection (AOI), offering 7 types of inspection equipment used in processes such as HBM incoming material and flip-chip bonding. This division has received certification from a leading foundry for CoWoS and SoIC platforms, with CoWoS-related revenue accounting for approximately 75% of its semiconductor equipment business [2][2][2] - **Milestone Achievement**: The certification from the leading foundry is considered a key milestone for Ta Liang, facilitating smoother entry into the OSAT supply chain as OSAT manufacturers expand their 2.5D capacity [2][2][2]
