CI1000™ FEATURES
The CI1000™ Automated Controlled Impedance Testing
System is designed to lower the cost and maximize the throughput of the TDR
measurement process.
Manual TDR probing induces error in the
measurement process. The current error window of TDR instruments and the manual
probing process limits the type of measurements which can be taken, the length
of the trace that tests can be conducted on, and dictates the use of test
coupons. The CI1000™ automated system eliminates those restrictions by providing
high accuracy. This accuracy allows measurements to be taken on live traces as
well as on coupons.
Robot Assembly
 The
CI1000™ robot assembly is designed to quickly,
accurately and repeatably move the Probe Assembly onto the board, coupon, or
panel under test. The assembly is a four (4) axis robot which includes rotation
of the probe to allow testing of all orientations of test pads. The assembly's
working envelope is 1000mm (39.3") x 750mm (29.5") with 360 degree
rotation and extend/retract capability of 225mm (8.9"). The robot moves
quickly (over 65 inches/sec) with an example point-to-point move from one test
point to another of 12" including extend/retract being completed in 0.3
seconds. The repeatability of motion of each part of the robotic assembly is
+/-0.01mm (+/-0.0004"). The robot is mounted in the horizontal position to
allow easy manual load/unloading of boards to be tested. This configuration
supports the standard SMEMA conveyer standard interface which allows third party
automatic load/unload equipment to be incorporated with the CI1000™.
Operator's Station
|
 The operators
station consists of an operator interface (flat
panel monitor, keyboard, and mouse) on an ergonomic
swing arm and a system controller (PC computer). A
windows style graphical user interface (GUI) runs on
the System Controller to provide a way for the
operator and other personnel to access the CI1000™
system. The GUI provides all the necessary
functionality to operate the CI1000™: |
 |
System Log-in:
Three (3) levels of access is permitted (Operator, Management, Maintenance). |
|
|
Run Tests:
Tests can be started with simple keystrokes (or mouse button clicks). |
|
|
Test Monitoring:
Several screens allow the operator and/or manager to monitor the testing
operations. |
|
|
Automatic Test Data Handling:
The necessary information about the specific board (panel) characteristics can
be imported from the boards CAD/CAM files using the Introbotics file format. All
imported data is stored in the CI1000™ systems relational database. Test results
are also stored in the database and are available for exporting to the CI1000™
reporting package or the users plant SPC system. |
|
|
Manual Teach:
If CAD/CAM data is not available, the CI1000™ has a manual teach capability
utilizing the camera system which allows the user to quickly and accurately
teach the desired test points. |
|
|
Measurement System Verification:
The GUI provides the ability for the operator at any time to instruct the
CI1000™
to self verify the accuracy of its measurement system. |
|
|
Interface to Equipment:
The GUI provides interface to standard and optional equipment including the TDR
Instrumentation, SPC System, Board Load/Unload Equipment. |
Flexible Board
Holder
The flexible board holder allows a variety of
board sizes to be mounted easily and quickly onto the CI1000™ for testing. The
board holder supports mounting of boards from 5-1/4" x 1/2" up to
36" x 28.5". The holder has pneumatic foot pedals (to leave hands
free) which control the opening and closing of the holders moving clamp. The
operator simply places a board onto the bed of the holder and then closes the
holder's moving clamp. The holder will simultaneously lift the board off the
holder bed (leaving an air gap below the board) and clamp the board firmly and repeatably in place for testing.
TDR Probe Assembly
The TDR Probe Assembly includes all components
connecting the TDR sampling head to the probe tip. This assembly is designed to
maximize the measurement accuracy. The assembly includes the following:
-
High Frequency Connectors (SMA and 3.5 mm)
-
High quality flexible coax
-
Introbotics High Frequency Probe (Patented)
The assembly provides a very accurate measurement
with high resolution. This is achieved through the use of the TDR
instrumentation, high quality coax components to connect the instrument to the
probe, and Introbotics high frequency probe. The combined probe assembly
produces a rise-time at the probe tip of 35 psecs and a fail-time of 50 psecs.
This allows accurate measurements on traces as short as 1/2" and high
resolution of impedance discontinuities on longer traces.
The Introbotics probe is extremely robust and is
designed for manufacturing operations. The probe tip itself does not utilize
pogo pins and does not have any moving parts that can wear out.
Camera System
CI1000 Camera |
A high resolution camera and lens
assembly is mounted to the robotic system for fiducial finding or to simplify
the manual teach process. |
Verification
Station
|
The verification station consists of a standard
50 calibrated airline (an 28 airline assembly can be substituted or added) which
is mounted inside the robot probing area. Upon operator command or at a
predefined interval the robot will move the probe assembly up to the
verification location and verify the system's TDR measurement accuracy. |
 |
Probe Tool Stand
The probe tool stand contains four (4) slots to
hold up to four (4) probe tools at a time for automatic pick-up by the CI1000™
robotic system. Each slot is monitored for the presence of a probe tool.
Currently up to two (2) tool stands (for a total of six probe tools) can be
mounted in the robot area.
|
|
Tool Changer-Robot Side
The robot side tool changer is fixed to the end
of the robot arm and allows the robot to automatically pickup a variety of probe
tools. It contains all of the necessary electrical hook-ups including high
frequency coaxial disconnects and a tool identification system that can identify
which probe tool the robot currently is utilizing.
|
|
|
Tool Changer -Probe Side
The probe side tool changer is mounted to the
Introbotics probe assemblies to allow the probes to be utilized with the Tool
Changer system.

HFT Report Writer
The CI1000™ comes complete with a flexible data
reporting package called the HFT Report
Writer™. A report can be generated locally or
sent over the net. Extensive data sorting capability is provided to support
process analysis. Hardcopy printouts and electronic outputs are available in the
following formats:
-
Word
-
Excel
-
Adobe Acrobat (.pdf)
-
Rich Text Format (.rtf)
Please see HFT Report Writer™ for more details.
Base Table
The system's base table is wheeled
to support the weight of the equipment during transportation within the
facility. Leveling legs are also provided for permanent installations.
WaveForm Viewer™ and Screen Capture
Included with both the CI1000™ and the ACCU-Prober™,
the WaveForm Viewer™ allows graphic viewing of the the testing results of each
controlled impedance trace. TDR waveforms can be captured for each test point,
viewed off-line, and sent electronically to your engineers or customers. The
Waveform Viewer allows easy selection of the impedance measurement zone and
dynamically recalculates impedance for each selected zone. The viewer displays
controlled impedance, propagation delay, and dielectric constant information for
each trace. End and midpoint VIA affects are displayed and a dynamic cursor
provides readouts of impedance along the entire trace. Printouts can be produced
for documentation purposes.
