3 Terms

STU (SenstivityTestUnit) Transducer. Electrical and acoustic energy conversion devices to each other. Will be converted into electrical energy It referred to as transmit acoustic energy transducer; acoustic energy is converted into electrical energy receiving transducer. Transmitting and receiving transducers are usually It used separately, but can also be a share. Transducer key performance indicators are. operating frequency, bandwidth, electricity Sound frequency, impedance of the resonance frequency of the directivity (transmit beam width) and sensitivity.

4 Overview

Particle Impact Noise Detection System (PIND) is to detect the presence of components encapsulated cavity free particle EQUIPMENT Preparation. The main system consists of four components excitation means, ultrasonic testing unit, the oscilloscope and the transducer. Excitation device To provide an approximation of actual application of the components to be detected shock and vibration environment; ultrasonic detection means for detecting particles Shock and vibration noise emitted in the process; oscilloscope is used to observe the level of the signal and the detection threshold; transducer used to assess Sound sensitivity performance PIND ultrasonic detection unit.

5 Metrological characteristics
