The Spectral Dynamics SD Felix 4540M4 PIND System is a high frequency particle impact noise detector with a 155kHz ultrasonic sensor capable of detecting particles as small as 15 microns in diameter (0.01mm). Spectral Dynamics 4540M4 PIND testers utilize crystal sensors to identify loose particles moving within electronic components. The SD Felix system operates by recording acoustic, vibration, shock and current amplifier output data via four unique channels of data collection. All four channels digitize the data at 2.5M samples per second. In military test applications, the unit fulfills and exceeds MIL-STD-883, MIL-STD-750, MIL-STD-202 and MIL-STD-39016D requirements.
