PIND refers to particle impact noise detection, which detects loose particles in packaged components such as integrated circuits through shock and vibration generated by shaker. PIND products of Chengdu PIND Instrument Co., Ltd. will give users simple, reliable, and inexpensive tools to perform Particle Impact Noise Detection (PIND) testing.

The application of our product greatly improves the reliability of electronic components.

P.I.N.D.--Particle Impact Noise Detection

Vibration, Shock and Acoustic means are used to ensure the reliability of electronic components

In the past 10 years, Chengdu PIND Instrument Co., Ltd. has been committed to providing users with simple operation, reliable performance and cost-effective particle impact noise detection equipment and related technical services, the application of this equipment has greatly improved the reliability of electronic components products.

Our PD series particle impact noise detector can detect loose particles moving freely in the cavities of electronic components including relays, transistors, hybrid circuits, integrated circuits and switches. These particles are often the potential cause of short circuits and serious system operation failures.

The shaker is used to excite loose particles in the cavity of the component. The energy of the particles striking the cavity housing is converted into a wide-band pressure wave, which passes through the housing and is detected by a sensitive ultrasonic sensor mounted on the test equipment. In order to ensure that the particles can make accurate impact motion, we use sensors to provide feedback vibration signals to the controller, and through the controller to control the closed-loop shaking table work.

PD series Particle Impact Noise Detector

ADVANCED TECHNOLOGY THAT'S EASY TO USE

Our PD series features packaging and is the most advanced system available today. Combining sensors that monitor and display the shaker motion with computer control to correct for any changes in test conditions, Our PIND test system generates accurate and repeatable test conditions. Its ultra-sensitive, ultrasonic (155 kHz) sensor with multiple crystals can detect particles as smaller than 15 microns in diameter impacting the package cavity.

The multiple computer technology not only controls the motion but also allows the user to program the motion including both shock and vibration at the precise amplitude and timing to simulate the whole range of testing requirements. The operator simply needs to input the desired impact amplitude and duration, or the vibration frequency, and the PIND system automatically calculates the appropriate frequency and drives the shaker to produce the appropriate motion. You will be surprised by the quick and easy way of programming and operation of PD series PIND equipment. The system functions can fully meet the requirements of relevant PIND test specifications.

PROGRAMMABLE SOFTWARE FOR MORE VERSATILITY

Using our software developed entirely based on engineering applications, PIND's operating system is customized to meet your specific testing requirements. Through Windows programming, greatly facilitate the use of operators.

System with a low-pass filtering feature will automatically reduce the vibration amplitude to perform low-frequency tests up to 25 Hz. Such test objects mainly include relays, hybrid circuits and components that need to be carefully tested. If other testing requirements, you can modify the parameter Settings to reality.

UNIQUE FEATURES OFFER CONVENIENCE AND FLEXIBILITY

Whether you're testing electronic components for cardiac pacemakers, manned spacecraft or undersea cables, you'll enjoy the convenience and flexibility of the special features which set our system apart from any other PIND test system.

Based on years of after-sales maintenance experience of mainstream PIND products, our technical developers ensure that the detection sensitivity of PD series particle collision noise detector is consistent with the current domestic mainstream PIND equipment standards, so as to ensure the reference and traceability of customer test results to the maximum extent!

·         The PD series system easily exceeds the requirements of all military standards for PIND testing(QJ 2863、QJ 789A、GJB65B、GJB128A、GJB548B、GJB360B、GJB2888A).

·         Imbedded sensors that monitor and display the actual shaker motion with computer control to correct for any changes in test conditions, the PD series system generates accurate and repeatable test conditions.

·         The unique PD series PIND 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.

·         The PD series system offers a low profile, low stray magnetic field design that eliminates any need for an expensive special test bench, required for conventional shakers with external shock fixtures.

·         The PD series system is an all-DIGITAL system with no knobs or screws to adjust. It is fully programmable to your own specifications or as required by military standard. Since everything is generated by the computer, the user can create different amplitudes, frequencies, and durations. There is future expansion to more complex motion environments including Random Vibration and advanced Shock conditions.
