Electromagnetic Compatibility Requirements
This product complies with EN 55011 (CISPR 11) Group 1, Class A for conduc ti ng emissions. The product excee ds the EN 55011 (CISPR 11)
Group 1, Class A limit for radiated emissi ons by less than 10 dB when measured on a test site at a distance of 30 meters. Therefore, some site
preparations may have to be don e in order to comply with the Class A lim it in th e frequency range of 30 MHz to 1 GHz for ra diated emissions at
30 meters from the exterior wall of a buil di ng i n w hi ch t he equi pm ent is installed. See the figure bel ow for an illustration of the site calculations.
To obtain the necessary at te nua ti on at the Customer’s site, perfor m t he se ca lc ul at ions (if the calculated site attenuation (A) is less than 10 dB,
contact the Technical Regulatory Support Engine er (T RSE) in your country):
1. The attenuation of a concrete wall (W) (without any openings) = 10 dB
2. The distance (D) (the distance from the equipment to the exterior wall plus 30 meters) increases the attenuation by X and can be calculated
as follows:
X = 20 * log (D/30)
Where: X = attenuation in dB
D = distance in meters
3. The total attenuation (A) is calculated as follows:
A = n * W + X
Where: A = total attenuation in dB
n = number of concrete wa ll s w ith in dist ance D
W = 10 (dB)

1-2 Introduction and Overview
5DX Series 3 What’s New With the Series 3?
What’s New With the Series 3?
The Agilent 5DX Series 3 includes the following upgrades and changes from the
Series II/2L:
• Panel Handling and motion control have been redesigned.
• The motion control driver assembly is integrated into the Motion Control
Assembly. There is no motion control power supply
• XYZ Stage initialization has been improved.
• Brushless motors are now used, eliminating the need to change motor
brushes.
• A mechanical “middle rail” option is available so two boards or panels can
be tested simultaneously for increased through put.
• The Power Subsystem has changed
• There are only nine power options available, reducing confusion of which
one to use.
• The isolation transformer and Brute power supply have been eliminated.
• The PDU now controls servo module power.
• External power outlets have been eliminated to reduce confusion about
what is or is not 5DX power.
• A new controller and expansion chassis are used.
• The new controller provides faster handling of information.
• The new expansion chassis uses primarily PCI bus components instead of
the older ISA components.

What is the 5DX Automated X-ray Inspection System? 5DX Series 3
What is the 5DX Automated X-ray Inspection System?
The 5DX System uses X-ray Laminography to examine solder joints on plated
through-hole, single and double-sided surface mount technologies (all common
package types), solder paste and grid arrays (solder bump, Ball Grid Array,
connectors), as well as, fine pitch Chip-On-Board assemblies.
The 5DX System can operate inline with the Printed Circuit Assembly
manufacturing process equipment and is designed to be used on PCA’s only.
X-ray Laminography is used to separate solder joints into individual layers, the
resulting detailed slice images are easily analyzed through gray level (256 gray
scale) processing.
The 5DX System is capable of a testing a single or double-sided board or a panel
of boards with an area of up to 455 x 455mm (17.5 x 17.5 inches).
How It Works
X-ray Laminography produces high-resolution cross-sectional slice images of
solder joints of a printed circuit assembly (panel). An electron beam generated by
the X-ray Tube is magnetically steered in a circular synchronous motion. The
electron beam is 180° out-of-phase from a rotating capture device called the
Rotary Scintillator. The Plane of Focus is produced in the area between the source
and the scintillator, thereby, ima ging a sli ce ima ge on the scint illator of the Rotary
Scintillator Assembly.
When a PCA is positioned within the Plane of Focus, the X-ray beam acts as a
penetrating source of illumination t hat forms a negative shadow on the scinti llator.
The phosphor molecules coating the scintillator become excited and radiate light.
The light is then viewed by the X-ray Image Camera and information is passed to
the imaging subsystem. The process of image averaging blurs out objects that
occupy areas above and below the Plane of Focus, while the area within the Plane
of Focus is clear. By this means various layers of the solder joints can be imaged
by moving the panel up and down through the Plane of Focus.

The PCA is loaded into the 5DX. For the 5DX to correctly test the solder joints,
the PCA has to be aligned. A surface map is made to compensate for variations in
the manufacturing process. The solder joints are measured and these
measurements are analyzed by the a lgorithms to determin e if they pass or fa il. The
algorithm thresholds, set up by the user will determine the pass or fail criteria. The
PCA is then unloaded from the 5DX.

5DX Series 3 5DX Overview
Safety Interlock Subsystem
The Safety Interlock Subsystem prevents the X-ray, Laser and Motion Driver
assemblies from operating in the event that any access panel is open. The Safety
Interlocks are used to prevent injury to personnel, the 5DX System and printed
circuit assemblies under test
127(
The X-ray Tube Dielectric Pressure Sensor is also connected to the
Safety Interlock Subsystem, and will automatically shut OFF power
to the X-rays if the vessel pressure fal ls below safe operating limits
(less than 2.8 kg/cm2 (40 psi)).
X-ray High Voltage Power Supply
The X-ray High Voltage Power Supply provides -160 kilovolts dc of conditioned
power required to operate the X-ray Tube. It also supplies +15 volts dc and -15
volts dc for the X-ray Tube Electronics. The X-ray HV Power Supply also
provides software controlled monitoring facilities, necessary to maintain a stable
X-ray source.
WARNING There are high voltages inside of the X-ray High Voltage Power Supply and
running through the High Voltage Cable. There are no User serviceable
parts inside of the X-ray High Voltage Power Supply. Do Not attempt to
open or otherwise service this item. Do Not remove the High Voltage Cable.
The X-ray High Voltage Power Supply produces -160 kilovolts dc of conditioned
power to drive the X-ray Tube, +15 volts dc and -15 volts dc for the X-ray tube
electronics. The X-ray High Voltage Power Supply is discussed in the power
subsystem chapter

5DX Overview 5DX Series 3
Panel Handling Subsystem
The Panel Handling Subsystem provides loading and unloading of printed circuit
assemblies (panels) for testing. The Panel Handling subsystem supports Surface
Mount Equipment Manufacturers Association (SMEMA) interface standards.
The Panel Handling Subsystem also positions the panel under test. This is done by
controlling the three mechanical motion axes (X, Y and Z) and the Autowidth
Adjust Motors. The X-Axis and Y-Axis are driven by servomotors, while the ZAxis is driven by four vertically positioned stepper motors. The rails in the XYZ
Stage Assembly are adjusted to the size of the panel by the autowidth adjust
motors.
Surface Map Subsystem
The Surface Map Subsystem maps the surface characteristics of each panel.
Components of the Surface Map Subsystem include the laser, the laser camera and
the surface mapping software. Surface measurement is required to facilitate the
accurate positioning of the Z-Axis in relationship to the Plane of Focus.
Imaging Subsystem
The Imaging Subsystem contains image acquisition hardware and software
necessary to generate slice image data. The process begins with the Electron Beam
and resultant Video images are digitized into 256 gray levels and analyzed.
Pneumatics Subsystem
The 5DX System contains several pneumatic assemblies. Pneumatics operate the
inner and outer barriers, the panel clamps on the XYZ Stage Assembly, and the
panel in place mechanical actuator.
System Controller and Expansion Chassis
Combined, the System Controller and Expansion Chassis provide the necessary
hardware I/O connections to operate the 5DX System. The System Controller
controls the 5DX System operations. Interaction is provided by the User Interface.
The System Controller contains the Frame Grabber PCA, the Transceiver PCA, the
floppy and hard disk drives, the DAT tape unit and the CD-ROM drive. The
Expansion Chassis contains a fourteen-slot backplane and is where the Motion
Control, Camera Control, Modem, Serial Port and Receiver PCAs reside.
