The current standards of modern electronics mean that it is important to guarantee high quality through accurate electrical testing. This requires a reliable electric connection between the testing equipment and the product under test (UUT). Columbia has developed a series of linear test fixtures especially for this purpose: the CMK series test fixtures. The reliability and accuracy of a test fixture are strongly determined by its mechanical construction. This is why CMK fixtures uses solid aluminium parts.
Columbia have created a unique mechanical click system using ball bearings and guiding sleeves. The UUT is connected to the spring contact pins that are connected to the testing environment in a completely linear fashion. Connecting the UUT to probes can beapproached both from the top and the bottom and, optionally, even from the side. The ergonomic housing provides generous spacefor additional measuring electronics. The back and bottom of the housing can be adapted to the various test system interfaces.
