Trio-Tech International was incorporated in 1958 under the laws of the State of California. The company has historically focused on providing reliability test equipment and services to the semiconductor sector. Over time it expanded its capabilities to include the design and manufacture of equipment for broader industrial applications. Today Trio-Tech International operates facilities in the United States Singapore Malaysia Thailand and China serving customers worldwide. The firm’s founder envisioned a business that would support the growing need for quality assurance in electronics. Over the decades Trio-Tech International has built a reputation for engineering excellence and responsive customer service.

The company generates revenue primarily from three activities equipment sales testing services and value added distribution. Equipment sales include burn in systems reliability test chambers and specialized tools used in semiconductor back end processes. Testing services are performed in dedicated labs located in Asia and cover electrical environmental and burn in evaluations. Value added distribution involves sourcing electronic components and test related products from global manufacturers and reselling them after customization to meet specific client needs. After sales support such as maintenance calibration and repair further contributes to the company's income. Research and development efforts are directed at improving existing products and creating new solutions that address emerging technology trends. The company also earns income from licensing its proprietary test know how to select partners.

The company operates through the following segments: Semiconductor Back-end Solutions and Industrial Electronics.

• Semiconductor Back-end Solutions designs and manufactures burn in systems burn in boards and related hardware that assesses the structural integrity of integrated circuits. The segment also offers comprehensive testing services that include electrical stress environmental exposure and burn in cycles performed to client specific standards. These services support customers during new product introduction by providing expert technical assistance and rapid prototyping capabilities. In addition the segment distributes burn in test related equipment such as boards sockets and connectors sourced from approved suppliers and resold after value added processing. By combining equipment manufacturing testing and distribution the segment aims to be a one stop solution for semiconductor manufacturers seeking to improve yield and reduce time to market. The segment maintains a team of application engineers who work closely with clients to tailor test protocols to specific device requirements. Continuous investment in automation and data analytics enhances the efficiency and repeatability of its testing operations.

• Industrial Electronics focuses on the design manufacture and distribution of test process and other equipment used in diverse manufacturing environments. Its product portfolio includes environmental chambers leak detectors autoclaves centrifuges dynamic testers HAST testers and temperature controlled chambers. The segment also provides preventive maintenance calibration repair and upgrading services for equipment that controls temperature humidity and pressure. Industrial Electronics acts as a value added reseller of components such as connectors sockets cables LCD displays and touch screen panels enhancing each item through custom engineering and integration work. Furthermore the segment serves as an extended research and development arm for customers helping them refine product designs and improve performance through expert engineering support. Industrial Electronics also provides on site installation and training to ensure that customers can operate equipment safely and effectively. Its service network spans multiple countries in Asia enabling rapid response to maintenance requests.

Within the semiconductor test equipment market Trio-Tech International competes with numerous independent testing laboratories and equipment manufacturers. The company leverages its six decade history deep technical expertise and long standing customer relationships to differentiate itself from newer entrants. Its reputation for reliability and consistent product performance helps retain business even during industry downturns. In the industrial electronics arena the company competes with broad line distributors and specialized equipment makers but distinguishes itself through value added services and customization capabilities. Long term partnerships with key suppliers give the company cost advantages and reliable access to critical components. The shift toward electric vehicles and renewable energy creates new demand for test equipment in the industrial sector.

The company serves semiconductor manufacturers integrated device manufacturers fabless firms and end users of electronic components across automotive computing data storage consumer and communication markets. Industrial electronics customers span sectors such as aerospace medical device manufacturing industrial automation and general manufacturing where test and measurement equipment is required. Geographically the majority of sales are made to customers outside of the United States with significant activity in Southeast Asia and China. The three largest customers together account for approximately forty seven percent of total revenue while a single major customer contributes about twenty one percent of revenue in the most recent fiscal year. Efforts to broaden the customer base have reduced reliance on any single account over recent years. Nonetheless the company continues to monitor credit risk and maintain stringent approval processes for new customers.
