Floor Requirements
The system tester (testhead and support bay, if included) is the heaviest part of the system. The
controller and test development stations present no special load-bearing concern. The following table
lists the approximate weights of fully-loaded systems.
Anti-Static Surface
Static electricity is destructive to your production process and to your board test system. Careless
handling and poor planning can cost you yield and system reliability.
This is not an exhaustive description of anti-static precautions but a reminder as you plan your system
area:
• Anti-static flooring. Plan to use an anti-static floor covering or mats.
• Grounding straps. Plan for foot straps in conjunction with anti-static flooring and wrist straps for
system operators. The testhead has external connectors for wrist straps.
• Anti-static DUT storage. Plan for anti-static tote bins for your devices-under-test and storage for
anti-static bags.

Moving Access Requirements
The system is shipped from the factory on one large crate (on a pallet) and several smaller crates or
boxes. The support bay, if included, is shipped on a separate pallet. The large testhead crate may be
too large to move to your system’s destination. If you cannot move it to its final destination, you will
need to unpack the testhead and roll it on its casters (see Chapter 8, Receiving and Moving
Instructions). Other smaller boxes, containing the controller and test development hardware, should
not present access problems.

Dimensions of the Crated System
Dimensions of the Uncrated System
When removed from the crates, the testhead and support bay can be rolled on their casters. This may
make them easier to move.
Table 3-4 lists the dimensions of the uncrated testhead and support bay. Chapter 8, Receiving and
Moving Instructions describes moving the tester on its casters.
Table 3-3 Dimensions of the crated system
System Type Dimension Measurement
Testhead Width 2095 mm (82.5 in)
Depth 1080 mm (42.5 in)
Height 1600 mm (63 in)
Support bay Width 1120 mm (44 in)
Depth 860 mm (34 in)
Height 1600 mm (63 in)
When moving a four-module system that has already been installed, you must move
the testhead and support bay together, subject to the restraint imposed by the cabling
between them. Be very careful not to damage system cables during moving.
3-4 Site Preparation
3 Structural Requirements
Access Requirements
• Ramps
When moved on its casters, the testhead will negotiate ramps with inclines up to 8% before the
leveling feet drag on the floor.
• Hallways and door
As a rough guide, if you have room to move a 4-foot by 8-foot (1.25 m x 2.5 m) sheet of plywood,
parallel to the floor, through hallways and doors, you will be able to move the crated testhead. If
you cannot move the testhead crate all the way, remove it from its crate in a receiving area and
push it on its casters to the destination.
