This document outlines the design elements that address the welfare and safety of the user and facility where an RI8611A Cassini V93K CTH Infrastructure (Cassini Infrastructure) is installed and stored. The Roos Instruments model MZYB336A Cart for Cassini V93K CTH Infrastructure storage includes static safe lockable casters and two push bars for easy manipulation. The methods for attaching and removing the RI8611A Cassini V93K CTH Infrastructure from the Advantest V93000 SoC Tester (Advantest V93000 Head) are detailed in the following text. These instructions assumes the Cassini V93K CTH Infrastructure has been setup and a Fixture attached.
The Roos Cassini to V93000 connection is very similar in concept to that of a production Device Handler or Wafer Prober and the ATE System that makes measurements within a test cell. The two systems are independent devices with minimal interconnect. Both can be used without the other.
When in use the RI8611A Cassini V93K CTH Infrastructure hardware is manually docked to the V93000 just as a typical Advantest Load Board Assembly or Probe Card Assembly would be docked.
The RI8611A Cassini V93K CTH Infrastructure hardware weighs 18Kg and has 4 handles. Even though this is within a single person lift range, RI recommends a two person lift due to the Physical shape.
When not in use the Roos RI8611A Cassini V93K CTH Infrastructure hardware has an included cart (P/N MZYB336A) to facilitate storage. RI recommends that the cart have a static control chain contacting the floor in addition to the static safe casters.
Below is a picture of the RI8611A infrastructure being removed and from the RI cart to be placed on the V93K.
The Cassini configuration without the custom fixture and socket weighs approximately 34Kg. A fully loaded Cassini system (infrastructure plus instruments, and now including fixture and socket) is approximately 42Kg. This is within the 75Kg V93000 maximum DIB restrictions.
RI and Advantest have performed center of gravity/tipping calculations with the standard Advantest recommended manipulators. If alternate manipulators are used, the customer will need to perform the mechanical analysis for safety compliance.
RI8611A Cassini V93K CTH Infrastructure hardware, TIM instruments, and Test Fixture on Cart (P/N MZYB336A)
The Roos RI8611A Cassini V93K CTH Infrastructure system has only two external connections: 1) to IEC-320 C14 Male Plug AC Power mains and 2) via USB C to the Advantest V93000 test cell computer.
Power requirements of the Roos RI8611A Cassini V93K CTH Infrastructure system is low power 48V DC which is provided by an external commercial AC-DC converter (that is CE certified). This converter requires connection to AC mains (110-240VAC and a total power of only 400W).
RI recommends the Cassini AC Power Supply plugged directly into the V93000 test head AC power connection so that it takes advantage of the V93000 EMO and mains protection.
If the customer is using any other optional V93000 accessory that utilize this built in power connection, then the customer must provide a suitable connection that still maintains the EMO safety standards.
An options may be a 1 to 2 CE certified AC power splitter cable.
Safety / AntiStatic ground
When docked to the V93K the chassis both systems are grounded and connected via mechanical clamping at the DIB interface.

In addition, the RI8611A Cassini V93K CTH Infrastructure is connected to the safety ground via the AC-DC converter connection
to a mechanically attached wire (yellow green) to the RI8611A Cassini V93K CTH Infrastructure .
This ground wire is extended via a dedicated ground wire included in the cable connection between the converter and the mainframe.
