Custom Grid Array Technology for Medical Applications - 1

Custom Grid Array for Medical Custom Grid Array Technology for Medical Applications Specifically designed and tested to offer RF performance to medical systems Custom Grid Array layout to offer RF performance with the same stable signal integrity offered by cabled coax solutions but with reduced size, weight and cost. The use of spring probes and target contacts in a grid array layout reduces the size, weight, and cost of the connector. Comparing the relative size of the grid array and coaxial contact connectors in selected applications, the Spring Probe based Grid Array contacts occupy only about ½ the space of traditional coaxial contacts. Also by replacing pin and socket contacts with spring probes, cleaning the cable connector can be faster and easier since flat target contacts are simpler to clean than coaxial sockets, thus improving throughput in a medical devices. Features & Benefits ■ 50% smaller than cabled coax solutions ■ 30% cost reduction thanks to the material reduction and to the lower cost of the contacts ■ Up to 100k mating cycles ■ Temperatures: from 15° to 35° ■ Contact resistance ≤ 50m Ω ■ RF Performance from DC to 300MHz for the 2A and 4B configurations: -1dB of Insertion Loss

Custom Grid Array Technology for Medical Applications - 2

Custom Grid Array for Medical Pin Grid Array (PGA) Layout ■ Using a spring probe grid array allows for the designer to customize the number of ground pins used to optimize the performance of the connector for specific frequencies/ coil designs, saving size, weight, and cost while maintaining the performance of a coax channel where needed. Spring probe grid arrays also simplify cable termination activities by allowing mass solder termination to printed circuit boards. ■ This grid array layout shows multiple configurations that can be used for different purposes. The top configuration...
