P.I.N.D. - Felix Computer Aided Test System

Computer Aided Test System for

• Windows 10

• Easy Calibration

• Digital Power Amplifier

The Complete PIND Felix System

  • Precision Shaker with a crystal sensor system
  • DPA600 digital Amplifier and Felix controller system
  • Computer system with Felix™ 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

Felix Features

 For over fifty years the PIND Products Group of 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.
 Our non-destructive high frequency acoustic test monitors for loose particles moving inside high reliability internal cavity electronic components such as relays, transistors, hybrids, 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 (½mv2) 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 converted to 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.

Spectral Dynamics, Inc. is a leading worldwide supplier of systems and software for vibration testing, structural dynamics, and acoustic analysis. Spectral Dynamics' products are used for design verification, product testing and process improvement by manufacturers of all types of electronic and mechanical products.
