A Strategic Acquisition in 2023
In early 2023, Smiths Interconnect solidified its position as a global leader in semiconductor testing solutions by acquiring Plastronics, a renowned brand in the burn-in test socket field. This acquisition significantly expanded Smiths Interconnect’s product portfolio and market share, particularly in the burn-in test socket market.
As a pioneer in semiconductor test socket manufacturing, Smiths Interconnect has long been at the forefront of high-end testing applications for markets including high-performance computing and AI chips, smartphones, PCs, communications, and enterprise-level data centers. Notably, the DaVinci series high-speed test sockets that deliver unmatched performance in terms of pin count and fine pitch, reinforcing its leadership in high-speed testing.
With the addition of Plastronics’ expertise and product offerings, Smiths Interconnect is now better equipped to provide comprehensive testing solutions, meeting diverse customer needs.

Plastronics: A Legacy of Innovation
With over 50 years of experience, Plastronics has been a trusted name in the burn-in test industry, boasting the largest library of QFN product test socket part numbers. Its innovative product line includes burn-in test sockets, patented spring probes, and custom interface connectors tailored for industrial applications.
Central to Plastronics' success is the H-pin technology, a patented stamped spring probe that surpasses traditional spring probes in mechanical, electrical, and thermal performance. This design also enables cost-effective, automated mass production, making it a standout innovation in the industry.
The Importance of Burn-In Testing
Semiconductor chips, often called the "brains" of electronic devices, play a crucial role in delivering seamless user experiences. The burn-in test is vital for ensuring the reliability of these chips, allowing manufacturers to identify potential defects early in the production process.
By subjecting chips to extreme conditions such as high temperatures (100-150°C), low temperatures, or accelerated aging tests, Smiths Interconnect ensures product reliability, reduces failure rates, and enhances customer satisfaction. These rigorous tests not only improve product quality but also enable design and manufacturing refinements.
