PIND ( Particle Impact Noise Detection Test ) testing is performed in order to detect the presence of loose particles inside a device cavity. Loose particle contamination is often caused by dirt, fibers, solder residues and other elements trapped inside the cavity during the sealing process. Loose particles can be a cause of electrical anomalies (or other physical problems) which in their turn can cause abnormal functioning of the parts and affect their reliability.
