World-Class Manufacturer of Automatic Test Equipment

Welcome to TESEC, INC. Web site!

  For over half a century, TESEC has been a trusted name in the semiconductor and electronic component industries—synonymous with quality, innovation, and reliability. Since launching our first semiconductor test systems in 1969, TESEC has remained at the forefront of power device testing and semiconductor package handling technologies.

  Our SpeKtra DC Tester Series continues to set the industry standard for power discrete component testing, while the TESEC MAP Handling System revolutionized high-volume CSP device handling and remains the market leader in Film-Frame handling.

  Building on this legacy, TESEC has introduced the Ultra Series—a new generation of MEMS handlers delivering unmatched accuracy and cost-efficiency for tri-temp, high-volume production testing of accelerometer and gyro-based MEMS devices.

  Looking forward, TESEC is driven by our mission:

“To ensure the comfort, security, and safety of human life and the Earth through our testing technologies.” As global demand grows for energy-efficient, low-carbon technologies, we are committed to leading the development of advanced test systems for emerging high-power semiconductor technologies such as SiC and GaN. At the same time, we continue to innovate in test handling solutions for next-generation package types—including Strip / Lead Frame, MEMS, CSP, and advanced Molded Interconnect Systems.
