Section 3: Installation Model 9139B Probe Card Adapter Instructions
3-2 9139B-901-01 Rev. A / January 2019
Mechanical structure
The mechanical structure of the 9139B enables installation in a wide variety of probers. It consists of
a motherboard suspended from the prober ring. See the figure in
Probe card adapter standard
components (on page 2-1) for details.
Spacers inserted between the motherboard and prober ring connect the two assemblies. The length
of the spacers determines the overall stack height of the probe card assembly.
Safety
Failure to make sure that the safety interlock and safety shields and guards are properly
installed and arranged as indicated will put personnel in severe danger. Severe personal
injury or death due to electric shock or electrocution may result.
For the safety interlock to function properly, the device under test (DUT) interlock sensor
must be installed near the DUT connections and the interlock magnet must be installed on
the safety shield. It must be set up so that when the magnet is near the switch (interlock
closed) the operator cannot touch voltage-carrying conductors. If not properly installed, it will
render the interlock inoperative and place personnel at severe risk.
