Techniques for Standardization of Particle Noise in Electronic Packages

A model of the behavior of a particle being vibrated within an enclosed space is presented. This model predicts increased particle detection probabilities by varying vibration parameters. The independent variables of the model are the acceleration level and the package thickness of the device being tested. The dependent variable is the vibration frequency. Support experimental evidence is included. A miniature magnetostriction transducer for calibration of the Particle Impact Noise (PIN) system has been developed. The device can be fabricated into an easily operated, self contained unit for system testing during production line usage of the PIN system. It has also been valuable in testing individual components of the system.
