Cohu
Who are Cohu's primary customers and where do they operate?
The semiconductor back-end testing surge in 2025 turned Cohu into a core supplier of thermal subsystems and handlers for cutting-edge 3nm–2nm chips. Its evolution from TV instruments to integrated test-cell solutions makes it essential for chipmakers prioritizing zero-defect yields.
Cohu serves IDM and OSAT chipmakers, automotive Tier‑1 suppliers, and hyperscalers needing high-reliability test flows; major markets are North America, Taiwan, South Korea, Japan and Southeast Asia. See Cohu Porter's Five Forces Analysis.
Who Are Cohu’s Main Customers?
Cohu serves a B2B market focused on semiconductor manufacturers and assembly houses, split between Integrated Device Manufacturers (IDMs) and Outsourced Semiconductor Assembly and Test (OSAT) providers. The company’s revenue mix has shifted toward automotive and industrial end markets, driven by higher-margin, long-lifecycle applications.
Primary Segments
IDMs require custom, deeply integrated test solutions and now represent the more stable portion of Cohu’s revenue streams. OSATs drive high-volume, cyclical demand for standardized handlers and contact systems.
End-Market Mix
Automotive and Industrial combine for about 47% of revenue in the 2024–2025 fiscal period, while Computing & Communication contributed roughly 22%, with the remainder split across Consumer and Medical.
Customer Evolution
Demand has moved from standalone hardware to integrated test cells combining handling, contactors, and analytics—reflecting Industry 4.0 and multi-chip module complexity. Top-ten customers now account for nearly 40% of annual revenue.
Geographic & Strategic Partners
Key partners include global IDMs and tier-one OSATs in Taiwan and mainland China; notable customers include NXP and STMicroelectronics, representing concentrated, high-value relationships.
Segment Characteristics & Implications
The Cohu customer base favors long-term, high-reliability test solutions for safety-critical and high-voltage applications, making automotive and industrial customers strategically important for margin stability and revenue predictability.
- IDMs: stable, custom solutions; long purchasing cycles
- OSATs: volume-driven, cyclical demand; scale-sensitive

What Do Cohu’s Customers Want?
Customers prioritize lower Cost of Test and higher yields, demanding high-throughput, ultra-reliable equipment that supports extreme temperatures and robust thermal management for high-power AI and automotive chips.
Yield-driven purchasing
A 1 percentage point yield improvement can equal tens of millions in 2025 semiconductor margins, so buyers focus on throughput and reliability.
Extreme temperature capability
Customers require handlers and contactors rated from -40°C to 175°C for automotive-grade qualification.
Integrated one-stop solutions
Preference shifts to integrated systems that reduce compatibility risk and streamline support compared with multi-vendor stacks.
Thermal management for AI
High-power AI chips need advanced thermal control to test at full speed without throttling or damage; this is a critical unmet need Cohu addresses.
High switching costs
Loyalty is driven by technical support and consumables availability; production lines are calibrated to specific hardware, raising switching barriers.
Data-driven feedback loops
DI-Core analytics deliver real-time equipment insights, enabling product tailoring for regions—cost-optimized handlers for Asia, ruggedized systems for Europe.
Customer requirements summary
Key preferences center on lowering CoT, maximizing yield, integrated solutions, extreme environmental specs, and reliable thermal control; purchasing is technical and regionalized.
- Prioritize throughput and reliability to impact profitability

Where does Cohu operate?
Cohu’s geographical market presence is concentrated in Asia, which accounted for approximately 62% of revenue by mid-2025, led by Taiwan, China and Malaysia; the Americas and Europe make up the remaining 38%, with strong automotive demand in Germany and France.
Asia: Core Market
Asia drives the semiconductor test equipment market for Cohu, with Taiwan critical due to OSAT density and leading foundries supporting high-volume test and inspection sales.
China: Strategic Localisation
Cohu maintains strong China operations via local partnerships, targeting the expanding EV chip market despite geopolitical headwinds and export controls.
Americas: Onshoring Tailwinds
The U.S. market benefits from CHIPS Act-driven IDM capacity buildouts, increasing demand for onshore automated test equipment and handlers.
Europe: Automotive Strength
Germany and France are core European markets where Cohu holds leadership in power semiconductor and sensor testing for automotive supply chains.
Cohu localizes support with global service centers—Southeast Asia for rapid, high-volume OSAT support; Europe for collaborative R&D with automakers—and is expanding manufacturing in the Philippines while pursuing a targeted sales push into India as a long-term growth market.
Market Share Focus
Cohu concentrates on segments with high test intensity: OSATs, IDMs and automotive suppliers, aligning customer segmentation with regional industry clusters.
Service Network
Global service centers reduce lead times and support field calibration, contributing to higher retention among large semiconductor manufacturers.
Capacity Expansion
Recent manufacturing expansion in the Philippines increases regional production flexibility and shortens supply chains for Asian customers.
India Strategy
Cohu targets India’s emerging semiconductor cluster as a long-term opportunity, deploying sales resources to capture early-market share.
Customer Mix
Primary customers include OSATs, IDMs and automotive Tier‑1s; this customer mix shapes regional revenue distribution and product focus.
