Array High Speed Test - DaVinci Micro Test Socket

Impedance Controlled Coaxial Solution for High Speed Test

The rapid expansion of connected devices and data-intensive applications are driving the growing demand for highly efficient and adaptive high-performance computing solutions. Whether it’s a complex SoC for a mobile phone or gaming system, volatile memory or an automotive radar application, the core functions and performance requirements all are being manufactured in the smallest possible footprint. The need to add more functionality in the smallest possible size has led to a reduction in IC pitch to less than 500 μm. At the same time, the increased performances in system-on-chip affect pin-to-pin noise or what is often called crosstalk during testing.

DaVinci Micro fully shielded signal path negates the effects of cross-talk during test, allowing an immediate yield enhancement over non-DaVinci products.
