How Does Cohu Company Work?

How does Cohu drive quality for AI and HPC chips?

Cohu specializes in back-end semiconductor equipment that tests, inspects, and handles advanced ICs to reduce costly final-stage failures. Operating in 30+ countries, it integrates thermal, electrical, and high-speed handling to serve IDMs and OSATs globally.

Cohu combines modular testers, handlers, and thermal solutions into unified workflows that speed throughput and improve yield for customers producing complex chips. Its IP portfolio and global service footprint support scalability and uptime.

How does Cohu Company work? It aligns testing, inspection, and handling into a single automated process to validate performance and reliability before shipment. See Cohu Porter's Five Forces Analysis for strategic context.

Cohu optimizes the back-end semiconductor value chain by providing integrated test handlers, automated test equipment (ATE), and interface products that identify defects early and maximize yield for chip manufacturers.

Test Handlers

Robotic systems move diced chips through high-speed test flows while controlling extreme temperatures needed for automotive-grade and high-reliability devices.

Automated Test Equipment (ATE)

ATE platforms execute electrical and functional tests at scale, supporting diverse architectures from MEMS to power ICs and enabling early defect detection.

Interface Products

Contactors and probe solutions provide the physical interface between chips and testers, reducing integration complexity and improving test repeatability.

One-Stop Testing

Combining handler, contactor, and software lowers total cost of ownership and shortens time-to-market for customers with high-mix, low-volume requirements.

Cohu's operational footprint spans Malaysia, the Philippines, and the United States, aligning manufacturing close to Asian fabs while keeping R&D and engineering in Western markets to support its Cohu business model and Cohu company structure.

Operational and Financial Highlights

Key metrics illustrate the value proposition: test-driven yield improvement drives customer profitability and recurring service and spare revenue. In 2025 Cohu reported that backend test and handler solutions contributed a material portion of its revenue mix, with aftermarket and services representing a growing ~30% of revenue in recent disclosures.

• Global manufacturing in Malaysia and the Philippines reduces lead times for Asian customers
• High-end engineering in the U.S. supports product customization for MEMS and EV power devices
• High-mix, low-volume supply chain enables rapid customization and tighter integration
• Integrated offering reduces customer's integration cost and accelerates time-to-market

Cohu’s revenue model blends large-scale capital equipment sales with recurring, high-margin revenue from consumables, services and software, creating resilience against cyclical capital spending; as of 2025 roughly 55% of revenue comes from new system sales and 45% from recurring sources.

Capital equipment sales

New systems like Neon and Diamondx drive large one-time revenues tied to chip design cycles and capacity expansions.

Consumables and wear parts

Test contactors, pins and interface products wear out and require frequent replacement, supporting steady aftermarket sales.

Service contracts

Tiered service agreements provide maintenance, rapid repair and guaranteed uptime, often multi-year and margin-accretive.

Software and diagnostics

Licensed software adds predictive maintenance and analytics, sold via tiered pricing to boost recurring revenue and customer lock-in.

Spare parts and upgrades

Decade-long hardware upgrades and spare parts for installed bases create lifecycle revenue and higher lifetime customer value.

Geographic mix

Asia accounts for the majority of sales due to OSAT concentration, while North American and European design-in activity fuels premium automotive and industrial contracts.

The mix enables Cohu to monetize interface-specific products and capture value across the testing platform lifecycle; see corporate strategy and values here: Mission, Vision & Core Values of Cohu

Revenue composition and metrics (2025)

Key financials and monetization insights for stakeholders and investors evaluating Cohu business model and Cohu semiconductor testing offerings.

• System sales: ~55% of 2025 revenue, driven by Neon/Diamondx platform deployments.
• Recurring revenue: ~45% of 2025 revenue from consumables, service contracts, software and spare parts.
• Aftermarket margins: Consumables and services typically deliver materially higher gross margins than capital equipment.
• Regional exposure: Majority revenue weighted to Asia, with strategic design wins in North America and Europe for automotive/industrial customers.

Cohu's transformation from a handler specialist to a full automated test equipment provider reshaped its addressable market and fortified its competitive edge through strategic acquisitions, thermal innovation, and a large installed base.

Key Milestone: Xcerra Acquisition

The 2018 acquisition of Xcerra moved Cohu into the ATE market, expanding its addressable market by several billion dollars and enabling end-to-end test and handler offerings.

Strategic Move: Advanced Packaging & Chiplet Inspection

In 2024 and 2025 Cohu prioritized entries into advanced packaging and chiplet inspection, capturing demand from heterogeneous integration and system-in-package trends.

Product Innovation: Thermal Sub-systems

Launches of high-end thermal sub-systems addressed AI processor heat dissipation, supporting operation across minus 55 to plus 175 degrees Celsius for HPC, aerospace, and automotive customers.

Installed Base & Ecosystem

Cohu maintains an installed base of over 24,000 systems globally, creating high switching costs and an ecosystem advantage that supports recurring equipment and services revenue.

Cohu's business model blends equipment sales, service and spare revenue, and R&D-driven product upgrades; lean manufacturing and balance-sheet strength helped weather the 2023–2024 inventory correction while preserving investment in growth verticals.
