Teradyne makes automated test equipment that helps chipmakers and electronics companies check whether their products work properly before they ship. Its main products are testers used for semiconductors, circuit boards, and other electronic components, plus robotic systems for factory automation. The company sits at a critical point in the electronics supply chain: customers use its machines to catch defects early and to keep manufacturing lines running reliably.

The main customers are semiconductor manufacturers, electronics makers, and industrial companies that want faster, more precise testing or material handling. Teradyne makes money by selling test systems, software, and related support services, including upgrades, maintenance, and replacements. In robotics, it sells collaborative robots and automation systems through distributors and direct sales to factories that want to automate repetitive tasks.

What makes Teradyne different is that its business depends on technical know-how and close ties to customers’ production processes. Its test equipment is often designed around the specific chips or devices a customer makes, which creates switching costs and long product cycles. That gives Teradyne a role as a specialized toolmaker for advanced manufacturing, rather than a mass-market hardware seller.
