Revision 1.0:  April 2020

This guide helps you get started using Intermittent Fault Detector (IFD) test equipment and facilitates the discovery of all its amazing capabilities.

General

Supported IFD Models

• Intermittent Fault Detection & Isolation System™ (IFDIS™)
• Intermittent Fault Detection & Isolation System 2.0™ (IFDIS 2.0™)
• Portable Intermittent Fault Detection™ (PIFD™)

Introduction

Universal Synaptics is the industry leader in detecting and isolating elusive intermittent faults in accordance with the Department of Defense MIL-PRF 32516. The massive digital testing void that exists today with conventional scanning test equipment, led to  he development of the patented portable Intermittent Fault Detector™ (IFD™), the Intermittent Fault Detection & Isolation System™ (IFDIS™) and the Intermittent Fault Detection & Isolation System 2.0™ (IFDIS 2.0™) family of Intermittent Fault Detectors. Our primary mission is to provide test solutions to the Department of Defense (DoD), commercial aircraft operators, Maintenance Repair and Overhaul (MRO) facilities and electronics manufacturing organizations to solve their intermittent failure problems to drive Customer Solutions across existing and new platforms.

Each IFD utilizes Synapse™ application as the user interface for testing and operation. The remainder of this guide will navigate you through the application’s functions and the steps needed to successfully test for and isolate intermittent faults.

Operation

Testing

From the “Home” screen – Press Start.

If a Map has not yet been selected, the top drawer will advise that a selection is required. Select a Map Group and a Map.

Enter the Serial Number of the Unit Under Test (UUT).

Once a Map is selected, press Start.

All tests will automatically run unless a fault is discovered during the testing process. If any of the tests fail, an operator action will be required to continue testing.

All IFD™ models perform the following tests automatically:

• Continuity
• Shorts
• Intermittence
• Fault Isolation*
• Reports

*Fault Isolation will be skipped if no intermittences are detected.

Meter
During testing, a meter pop-out icon will be available in Continuity, Shorts, and Fault Isolation. The meter can be used to monitor an intermittent connection or series of connections for fault isolation.

Sensitivity
Intermittence detection sensitivity can be adjusted only while Intermittence testing. At the start of Intermittence, sensitivity should be adjusted until no noise is detected by the intermittence hardware. This can be done by using the pareto chart while adjusting sensitivity until there are no new intermittence events.

As shown above, the bottom of the meter will display the test point numbers and the corresponding nomenclatures. As the meter value changes, the meter range will be displayed on the top left. The meter value will be displayed in red when the read value is out of the defined tolerance for that test point.

Icon & Drawer Glossary

Home Screen – Icons

Home Screen – Icon Indicators

Continuity, Shorts, and Intermittent are pass/fail tests. These Icons will be outlined depending on the current state of the test. A green outline indicates a test that has passed (example shown below). A red outline indicates a test that has failed. Fault Isolation and Reports are outlined in green by default.

Left Drawer

The Left Drawer can be used to navigate between the “Home” screen and other information screens.

Top Drawer – Left

Test Settings located in the Top Drawer is separated into two sections: Map Selection and Sensitivity.

Map Selection is used to select the Map Group and Map for testing. The Serial Number input block is used by Synapse in the Reports for documentation.

NOTE: Sensitivity is only active during Intermittence Testing and is used to adjust the sensitivity of the hardware to intermittent events. Adjusting sensitivity can be done by dragging the dial or pressing the plus/minus icons.

Top Drawer – Right

The Results portion of the Top Drawer includes the selected Map Graphic as well as a table containing the failed results, if any, of the selected test. Test results are available at the completion of Continuity and Shorts and live during Intermittence testing. The Fault Isolation table is a duplicate of the Intermittence Results with the addition of a meter pop-out icon . The meter pop-out icon is also available in the Continuity and Shorts results table.

Results can be accessed only after a test is started/ran. The respective test icon will be inactive until results are available. Additional icons displayed on the Results panel include Start/Continue and Rerun.

During Intermittence, two additional icons will become available/active: stop and Pareto . Stop must be used to end Intermittence testing and the Pareto icon will display a Pareto chart representing the live intermittence results. The Pareto can be used in addition to the results table.

In addition to the above, Continue and Rerun icons are available to continue on to the next test or rerun the current test.

Tests Explained

Continuity

A continuity test verifies that current will flow in an inteded electrical circuit. The test is performed by placing a small voltage between 2 or more endpoints of the circuit. Continuity testing is performed utilizing a digital multimeter to measure the resistance between the endpoint. In continuity testing the resistance between two points is measured. Low resistance means that the circuit is closed and there is electrical continuity. High resistance means that the circuit is open and continuity is lacking.

Shorts

A short circuit is any electrical flow that strays outside its intended circuit with little or no resistance to that flow. The usual cause is bare wires touching one another or wire connections that have come loose. The immediate impact is that a large amount of current suddenly begins to flow. This condition is known as a “short” circuit because the current is bypassing the full circuit wiring and flowing back immediately to the source by a shorter pathway.

Intermittence

Intermittent faults occur randomly in time, place, amplitude and duration. The very nature of the failure mode suggests that the ability to detect and further isolate the intermittence root cause is based on detection sensitivity and probability rather than conventional methods concentrating on ohmic measurement accuracy. You can’t detect an intermittent fault until it occurs, and you must be on the specific intermittent circuit when it does in order to detect and isolate the intermittent fault.

The Intermittent Fault Detector (IFD) family of testers utilize a proprietary, patented hardware neural network to continuously and simultaneously monitor every electrical path in the Unit Under Test (UUT).

Fault Isolation

Fault Isolation is the method used to identify the root cause for a failure that has been detected by the IFD during Intermittence Testing.

Reports

Reports automatically save after each test run whether the test passes or fails. At the conclusion of the testing sequence, a Full Report of the last set of testing results is saved automatically. Each report includes the Map Group and Map name, Serial Number of UUT, and the date of the test. Simply click the Reports icon and the Synapse Reports folder will open.
