The SPCB-1 Spring Clip Board does not require the usual sample bonding process invoving the use of small wires.

The Spring Clip Board is for use with the 0.55 Tesla magnet kit (not the 1.0T) and it has spring loaded clips and spring loaded tips to make contact without using bonding wires. (When using the Spring Clip Board, usually the contacts must still be annealed with a conductive material such as indium to insure good probe contact)

SPCB-2 Spring Clip Board

 

The SPCB-2 Spring Clip Board is for mounting thicker samples that are from 2mm up to 4.5mm in thickness.
