Driven by the rapid development of applications such as AI, electric vehicles, the Internet of Things (IoT), and smart healthcare, the global electronics industry is accelerating its transformation and creating a new wave of opportunities and challenges for the components supply chain. Taiwan boasts a solid foundation in key areas such as MEMS sensors, passive components, and printed circuit boards (PCBs). Despite the international political and economic uncertainties and the market fluctuations in 2025, the industry remains strong in its growth momentum and strategic resilience.

In the first half of 2025, the MEMS sensor market held steady amid low-seasonal effects and cautious demand sentiment. However, as the markets for automotive electronics, AI sensing, hearing aids, LiDAR, and human-machine interfaces continue to expand, the industry holds optimistic expectations for purchase order pull-ins from new projects in the second half of the year. According to estimates by the Industrial Technology Research Institute (ITRI), the production value of MEMS sensors is projected to reach NT$223.2 billion for the year, up about 2.5% year-on-year. 

This growth is largely driven by the rapid development of new applications such as AIoT, electric vehicles, and smart healthcare. There is an increasing demand for high-performance sensor solutions with low power consumption. Given their small size, low power consumption, and high sensitivity, MEMS sensors have become an indispensable key component for these applications. As system design is moving towards modularization and miniaturization, the trend for the customization and integration of MEMS technology is bringing new growth momentum to the industry. 

Whilst the demand for sensors continues to expand at a steady pace, the passive components market is slowly stabilizing. The changes in the U.S. tariff policies are putting the global electronics supply chain under pressure to restructure. Shipments in the first half of 2025 were boosted in anticipation of potential tariffs with the demand for AI servers showing the most significant growth during the period. That said, the market is also concerned that stockpiling in the first half of the year may dilute order momentum for the second half of the year. If the demand fails to meet expectations, full-year revenue could be under pressure. Overall, the production value of passive components from Taiwan is estimated to reach NT$250.7 billion in 2025, up by about 4.2% from the prior year and reflecting steady growth amid the uncertainties.

The robust demand for AI servers and satellite communications applications continues to serve as the growth engine of the PCB industry in Taiwan. However, the U.S. tariff policy has become one of the biggest variables for the market this year. In tandem with the ongoing supply chain adjustments in response to the anticipated tariffs and the allocation of countries of origin, the PCB industry is witnessing a short-term boost in shipments and strong business performance in general. Nonetheless, it remains to be seen whether this wave of pull-in shipments now comes at the expense of lower demand in the second half and weaker order momentum going forward. Overall, the production value of the PCB industry in Taiwan is projected to reach NT$866.1 billion in 2025, marking a 6.0% increase on the previous year. 

While the markets for sensing and passive components continue to advance steadily, the PCB industry has emerged as another bright spot in Taiwan’s electronic components market for 2025, driven by the growing momentum of AI and satellite communication applications. That said, the PCB sector also faces significant uncertainty due to U.S. tariff policies in a way similar to the passive components market. In response to potential impacts, some companies have been adjusting production locations and supply chain configurations in advance, which has indeed boosted shipment volumes in the short term. 

Although the first half of the year benefited from the growth momentum driven by inventory stockpiling, the market remains cautious about demand sentiment in the second half of the year. If momentum weakens in the latter half of the year, it could place pressure on order visibility and overall production value.

As far as the MEMS sensors, passive components, and PCB industries are concerned, Taiwan has demonstrated solid technological capabilities and a high degree of flexibility by responding to the changes in demand from different use cases and policy shifts and achieving steady growth with strategic agility. As AI, electric vehicles, and IoT applications develop and evolve, the demand for high-performance components with low power consumption will continue to rise. That said, uncertainties such as tariff policies, geopolitical risks, and economic fluctuations persist. To maintain a long-term competitive edge, industries in Taiwan must continue strengthening their supply chain resilience, advancing technological differentiation, and deepening international collaboration.
