Introduction
The EM-Tec C-Square multi pin stub holders are primarily designed to hold multiple Ø12.7mm and/or Ø25.4mm pin stubs with the standard 3.2mm pin diameter. Larger or smaller pin stubs can also be used on the EM-Tec C-Square multi pin stub holders. They offer optimum X-Y coverage of the SEM stage and allow for easy alignment with the square sides and additionally engraved lines in X-Y directions. To facilitate quick and easy loading and exchange of the pin stubs, proprietary conductive gripping O-rings hold the pin stubs in place and provide a conductive path at the same time. The EM-Tec C-Square multi pin stub holders are available in 7 different sizes:
