Johnstech Verticon™ 100 BGA Test Sockets
For QFN, DFN, and other Pad-Style Applications

For High Speed Digital, RF, and Precision Analog Applications

Exceptional Electrical Performance.

The very short electrical contact length of the Verticon™ 100 BGA contactor, makes it very well suited for high frequency wireless and microwave applications as well as high-speed digital interfaces. The combined contact profile design and proprietary plating enable low and stable contact resistance measurements. This makes the Verticon™ 100 BGA well suited for precision low noise DC measurements.
