Historical Context

The Semiconductor Assembly and Testing Services (SATS) market is changing quickly because of the increasing need of advanced packaging, miniaturized chips and effective quality assurance procedures. AI, 5G, automotive electronics, and IoT applications are highly growth-driven and necessitate efficient assembly and cost-optimized performance as well as the high level of testing. There is also a shift to green manufacturing practices in the industry and the prime movers are using energy efficient fabs, water recycling systems and environmentally friendly packaging. On-going system-in-package (SiP) and fan-out wafer-level packaging research and development in the area of system-in-package and the new technology of test automation is rendering SATS essential to scale semiconductor innovation worldwide.

Impact of Latest Tariff Policies

The semiconductor supply chain has been derailed by trade tensions between the U.S., China, and the European Union that have impacted the supply of raw materials, wafer equipment, and high-tech test systems. Increased tariffs on semiconductor devices, electronic parts, and manufacturing equipment are leading to increased costs which have made SATS providers take increased costs or raise service charges.

The limitation to small and mid-sized SATS firms is a disproportionate impact since they have relatively limited access to suppliers and little financial flexibility when compared to large integrated device manufacturers (IDMs) and international outsourced assembly and test (OSAT) giants. Regional players have postponed capacity growth or relocated business to tariff favorable locations like Malaysia, Vietnam and Taiwan where subsidies by their governments and low labor costs give them competitive advantages.

This trend gives the big multinational OSAT suppliers a stronger edge, as they enjoy global sourcing, diversified manufacturing, and huge investments in research and development.
