The Optimum Conditions of Loose Particles Detection for Microelectronic Packaging

To achieve effective detection of loose particles within small cavities in microelectronic devices, this paper proposes the optimal detection conditions of loose particles in ceramic packaging for microelectronic devices based on simulation. Through establishing a particle-cavity collision dynamics model in ADAMS, the motion process of particles under sinusoidal excitation is simulated. Subsequently, the paper examines the impact of different accelerations, frequencies, loose particles' properties, and cavity heights on optimal detection conditions. Furthermore, the paper presents the optimal conditions for vibration testing, providing a valuable reference for the effective detection of loose particles in hermetically sealed microelectronic devices.
