Smiths Interconnect Expands DaVinci Test Socket Offering

Article by: Smiths Interconnect

The new DaVinci Micro test socket from Smiths Interconnect is designed for high speed testing of 0.35mm minimum pitch.

Smiths Interconnect has expanded its DaVinci product line to include the DaVinci Micro test socket, designed for high-speed testing of minimum 0.35mm pitch.

The rapid expansion of connected devices and data-intensive applications is driving a growing demand for highly efficient and adaptive high-performance computing solutions. Mobile devices such as cell phones, tablets and car infotainment systems are equipped with the most sophisticated systems on a chip (SoC) ever produced. In fact, these SoCs must combine CPU, GPU, AI engine, camera processor, memory and 5G modem in the smallest possible form factor.

The demand for increased functionality in the smallest possible footprint has led to a reduction in the pitch of integrated circuits to below 500μm. At the same time, the increased performance of SoCs affects pin-to-pin noise or what is commonly referred to as crosstalk during testing.

Despite great efforts to improve packet design, size reduction inevitably leaves critical high-speed signal lines susceptible to crosstalk, causing false failures during testing.

This is the field of test engineering that Smiths Interconnect aims to break into with DaVinci Technology. The DaVinci Micro test socket leverages DaVinci coaxial technology for integrated circuit (IC) applications at 350µm pitch to provide ideal pin-to-pin isolation, canceling the effect of crosstalk during testing and dramatically improving accuracy chip performance testing. Its innovative design protects small diameter signal probes and ensures the product can be deployed and withstand the rigors of a production test environment.

“The addition of the DaVinci Micro high-speed test socket will enable Smiths Interconnect to offer a solution that can dramatically accelerate our customers’ innovation in high-performance computing, graphics and adaptive SoC technologies.” said Brian Mitchell, vice president and general manager of the semiconductor test business unit at Smiths Interconnect. “DaVinci Micro’s fully shielded signal path, which eliminates the negative effects of crosstalk during testing, provides an immediate performance boost that sets it apart from non-DaVinci products.”
