inTEST Corporation is a global supplier of innovative test and process solutions for use in manufacturing and testing in target markets which include automotive, defense/aerospace, industrial, life sciences, and security, as well as both the front-end and back-end of the semiconductor manufacturing industry.  Backed by decades of engineering expertise and a culture of operational excellence, inTEST solves difficult thermal, mechanical, and electronic challenges for customers worldwide while generating strong cash flow and profits. inTEST’s strategy leverages these strengths to grow organically and with acquisitions through the addition of innovative technologies, deeper and broader geographic reach, and market expansion.

We launched our 5-Point Strategy early in 2021 and successfully began the effort to drive growth, diversify our markets, expand our customer base and add new talent to enhance our team. 20220630 INTT Alliance Presentation FINAL 5



Founded in 1981, inTEST served the semiconductor industry with manipulator and docking systems to support ATE production test equipment at end users and OEMs. As the success of its engineered solutions grew the company established operations in Asia, quickly followed by a subsidiary in Europe. 

In 1997, inTEST joined the ranks of public companies with an initial public offering, ticker symbol INTT (NYSE). With this additional capital, inTEST expanded its presence in supporting production test with tester interface products by acquiring TestDesign in 1998.

With a strategy to broaden the company's semiconductor business to include thermal systems for electronics test, inTEST acquired Temptronic Corporation in 2000 and created the ThermoStream brand of temperature forcing systems known throughout the world today for characterizing ICs and devices.

In the mid-2000s, inTEST executed a strategy to expand the reach of thermal products outside of the semiconductor industry, resulting most notably as the leading supplier to optical transceiver production test customers. Continuation of the thermal strategy to handle conditioning of larger devices, inTEST acquired Sigma Systems, thermal chamber and plate products in 2008. This permitted the company to deliver thermal using conduction and convection for larger test articles such as electronic modules, subassemblies, and PCBs, used extensively in automotive, aerospace, defense, and industrial applications. The company has been expanding thermal electronics test ever since.

As the strategy for thermal evolved, inTEST looked to develop business in the industrial arena. That challenge was met most recently with the acquisition of Ambrell Corporation, a manufacturer of induction heating systems used in a myriad of industrial processes.

With the launch of the 5-Point Strategy, the Company became much more focused on both organic and acquisitive growth and completed three acquisitions in 2021.  These were North Sciences, Videology Imaging Solutions and Acculogic.  These additions enhanced our thermal, process and electronic test technologies.
