PIND
Built by the Experts
PIND
For reliability testing of all types of Ics / Relays / switches and hybrid electronics , detect the particles with our PIND Felix system.
For over fifty years, Spectral Dynamics Inc. has given users simple, reliable and inexpensive tools to perform Particle Impact Noise Detection (PIND) testing to increase the reliability of electronic components.
The PIND FelixTM is the most advanced system available. Combining sensors that monitor and display the shaker motion with computer generated control to correct for changes in test conditions, the PIND FelixTM test system generates accurate and repeatable test conditions while meeting or exceeding all of the globally recognized test specifications.. The PIND FelixTM is truly a technology that the industry has been waiting for.
To provide always the best to our customers, Spectral Dynamics Inc decided in 2019 to discontinue the manufacturing, marketing and sale of the Spectral Dynamics former PIND Model 4511. Any representation by others that a similar or like product with the same features, functions or model number advertised or available for sale by the Spectral Dynamics USA or an affiliate of Spectral Dynamics is an unauthorized representation by such parties.
Support and services are still available for all Spectral Dynamics PIND systems including PIND FelixTM, PIND 4511 and PIND 4501 in our offices in the USA and France (for Europe).
The PIND Felix™ System has been designed to detect loose particles in electronic components. The system is programmable to provide speedy and precise automatic testing in accordance with the various standards. The interactive interface allows the operator to enter the desired stored test sequence and to control the test with ease.
The solution is completely designed by Spectral Dynamics. As this system is designed, manufactured, and built by Spectral Dynamics the quality of both components and build is controlled.
The PIND FelixTM is composed of:
- Precision Shaker with a crystal sensor system
- DPA600 digital Amplifier and FelixTM controller system
- Computer system with FelixTM software
- STU (Sensitivity Test Unit) unit to verify that the system is functional.
The system performs five major tasks:
- Vibrate a test article
- Shock a test article
- Detect any particle contaminants within the cavity
- Display the detected impact signals created by the loose particles
- Record the motion environment and the acoustic signals detected
The controller driven shaker provides shock and vibration motion of the test article. The impact sensor detects signals generated by a loose particle within the cavity of the test article, converts the physical energy into electrical energy which is passed through the cables to the amplifier and detection circuitry within the controller. Indication of the presence of loose particle detection occurs when the Acoustic Impact signal exceeds the programmed threshold limit.
Key features of the PIND FelixTM solution:
- Sensors
Depending of the test, Spectral Dynamics can supply single crystal or multiple crystal sensors. All our sensors have a complete Faraday shield around each crystal to protect the sensor from unwanted stray electrical signals. The embedded accelerometer allows monitoring and display of the actual shaker motion with computer analysis and correction for any changes in test conditions.
- Shaker
The unique shaker creates accurate “Active Shocks” with adjustable shock levels by controlling the velocity of the shaker head and correcting for device differences prior to impact
- Advanced software (Windows 10)
PIND FelixTM software allows for data collection of the vibration, shock, and acoustic channels. Each type of signal can be replayed for more in depth understanding of the interactions between the acoustic noise and the motion environment. Visual and audio particle detection are integrated to easily control your component. The software is compatible with tools like Microsoft Office. Reports for presentation or printing are simple to do.
- PIND testing according to international standards and internal process
The PIND FelixTM easily exceeds the requirements of all military standards for PIND testing (U.S. MIL-STD-883, 750, 202,39016D). It is also fully programmable to your own specifications if so required.
Our high frequency acoustic test monitors for loose particles moving inside high reliability internal cavity electronic components such as relays, transistors, integrated circuits, and switches – particles that have the potential of causing short circuits and serious malfunctions in system operations.
A shaker is used as a linear motor to excite loose particles to move within the component cavity. Upon striking the lid of the cavity, some of the particle kinetic energy is converted to a wide band acoustic pressure wave that travels through the lid, through the attachment media and onto the top surface of the Impact Detection Sensor.
The acoustic wave is detected by the sensitive ultrasonic crystal or crystals within the sensor and is converted into an electrical signal. To keep the particle moving, a very accurate shock, generated internal to the shaker and controlled by the computer, monitoring the motion of the sensor, is employed.
In the PIND Test, the particles are never measured directly. As the loose particles are placed in motion with a vibration, shock, the system then detects the impacts of those particles as they contact the lid of the cavity.

Contact local Spectral Dynamics sales representative to find out more about our DFAT capabilities and experience as well as see the detail below MIMO Random acoustic Module.
The JaguarTM solution provides a complete software suite for all your applications.
MISO Control software (Multiple Input Single Output)
Tests configurations with multiple input and requiring only one output drive, can be configured easily with the Jaguar™.
Sine Module
The main analysis of the test consists in using tracking filter to bandpass the desired data, synchronizing the center frequency of the bandpass filter and locking it to the drive frequency. Our team is proud to provide one of the best tracking filters with the JaguarTM solution.
Random Module
The purpose of random excitation is to expose the test article to all frequencies, all phases, and all amplitudes in a truly random nature. The only condition to this is the customers shape must be produced and maintained, without losing the true random nature of the energy.
Shock
The JaguarTM uses patented adaptive control algorithm with transfer function updating and coherence smoothing to accurately and quickly compensate for non-linearities or time-varying changes in the dynamic load.
Mixed mode (Sine on Random / Random on Random / Sine & Random-on-Random)
The mixed mode consists in combining broadband, narrow band and tones to perform vibration tests.
MIMO Control software (Multiple Input Multiple Output)
As a majority of vibration testing is performed with single shaker excitation systems, conditions often exist where single excitation is not appropriate to achieve the desired test control and results. For these applications, Spectral Dynamics has developed a MIMO applications software suite to simulate the “real world” and allow a multiple channel input while allowing for multiple output drive generation.
MIMO Random Module
MIMO Random provide digital real-time closed loop shaker control for production testing, design qualification, and reliability testing applications. The system allows the definition, simulation, and closed loop control of random vibration excitation of a system with multiple exciters.
MIMO Sine Module
During manufacturing and use, all products encounter stress. MIMO sine tests are performed on both prototype and production-line products to ensure that the product will survive actual production and in-use conditions. MIMO sine vibration environments generally consist of a single sine wave frequency that changes frequency over time at several driving (excitation) points.
MIMO Shock Module
Do you have a need for closed loop control shock testing with multiple vibration actuators? Our MIMO Shock application is the solution.
MIMO Replication Module
This application allows the replication of field measured time history vibration data. Real vibration environment can be played back and controlled on the test system in a laboratory environment.
MIMO Random acoustic Module
Closed-loop acoustic tests are typically performed on products to ensure that the product will survive actual in-use conditions. Random acoustic environments are characteristically non-repetitive in time, the energy is generally present at all frequencies over a frequency range. This acoustic environment can accurately simulate many real-world operating conditions.
The JaguarTM can generate a wide range of random acoustic environments to satisfy nearly any commercial, industrial, or military test requirement. For instance, Direct Field Acoustic Testing (DFAT) for satellites can be performed thanks to the Spectral Dynamics’ MIMO random acoustic application.
