Cohu vs Semtech
Side-by-side comparison of AI visibility scores, market position, and capabilities
Mid-size semiconductor test handler and contactor specialist; ~$500M revenue. ABTS and Neon thermal test handler platforms serve mobility, automotive, and data center SoC testing.
About
Cohu Inc. was founded in 1947 in Poway, California and has grown into a leading mid-size provider of semiconductor test equipment through organic development and acquisitions. The company focuses on test handlers (which position chips in automated test systems), contactors (which make electrical contact between chips and test sockets), thermal management during test, and integrated test cell solutions. Cohu is a complement to ATE vendors like Teradyne and Advantest, providing the mechanical handling infrastructure that feeds chips into testers at high volume.\n\nCohu's product portfolio includes the ABTS (Automated Burn-in and Test System) platform, the Neon thermal handler for extreme temperature testing (-55°C to +165°C), and a comprehensive contactor library for BGA, QFP, and advanced packaging formats. Key served markets include automotive (ADAS, power management), mobility (smartphone application processors, modem chips), and data center (SoC, memory interface). Automotive reliability testing is a major growth driver, as automotive-grade chips require extensive burn-in and temperature cycling per AEC-Q100 standards.\n\nCohu acquired Xcerra in 2018 to significantly expand its handler product line and global service network. The company reported approximately $500 million in revenue, with margins impacted by semiconductor capital equipment cycles. As automotive electrification and ADAS content per vehicle grow, Cohu's thermal test handler business is expected to see sustained demand growth.
LoRa wireless IoT technology licensor and Sierra Wireless acquirer; ~$900M revenue. LoRaWAN ecosystem spans 250+ LoRaWAN networks in 170+ countries for LPWAN IoT.
About
Semtech Corporation was founded in 1960 in Camarillo, California and has evolved from a manufacturer of discrete semiconductors into a provider of high-performance analog and mixed-signal chips for IoT, data center, and wireless infrastructure markets. The company is globally best known for owning the LoRa (Long Range) modulation technology, a proprietary wireless protocol enabling long-range, low-power IoT connectivity that has been standardized as LoRaWAN.\n\nLoRa/LoRaWAN has become the world's largest LPWAN (Low-Power Wide-Area Network) ecosystem, with over 250 deployed networks in more than 170 countries and hundreds of millions of LoRa-based sensor nodes for smart cities, agriculture, utilities, supply chain monitoring, and industrial IoT. Semtech licenses LoRa IP and sells LoRa transceiver chips, generating recurring royalty and chip revenue as the ecosystem scales. The company acquired Sierra Wireless in 2023 for approximately $1.2 billion to expand into cellular IoT modules and managed IoT connectivity services.\n\nSemtech also produces high-speed signal integrity ICs (GearBox, ClearEdge) for data center optical interconnects (400G/800G Ethernet) and timing products for telecom and 5G. The company generated approximately $900 million in annual revenue, navigating integration challenges following the Sierra Wireless acquisition while maintaining LoRa ecosystem leadership.
