Pind testing
WebThe objective of the NASA project is to use Particle Impact Noise Detection (PIND) to determine the probability that the devices currently in inventory, will manifest failures due to loose particles. Since the minimum shorting distance in some devices are 0.125″, particles which are too small to cause a short circuit pose no threat. WebParticle Impact Noise Detection (PIND) The objective of the test is to find out if sealed cavity devices contain free-moving particle pollutants. This test procedure is intended …

Loose particle contamination … WebMar 11, 2024 · 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.
Webmagnetization shall be degaused prior to PIND testing. 3.3.2 Lead protection. When a device incorporates relatively long and flexible leads, the leads shall be suitably restrained from striking the shaker/fixture or striking each other during test. Care shall be taken to prevent damage caused by resonance. 3.3.3 Testing. WebHowever, if the part fails the PIND test, it must be decapped to verify the nature of the particle causing the failure because the PIND test cannot differentiate between conductive and nonconductive particles. X-ray radiography. X-ray radiography is a good method for nondestructive analysis of most device types.
