Large-Scale CT Inspection of Feed-Through EMI Filters for Space Application
A type of Feed-Through Electromagnetic Interference (EMI) Filter incorporating two discoidal (ring-shaped) capacitors was selected for use in the Europa Clipper spacecraft propulsion systems. Parts reliability specialists were aware of historical problems with the attach materials used to provide mechanical support and electrical contact within these devices, so therefore a screening was desired to ensure the longevity and ruggedness of units intended for the space environment. CT X-ray, a technology which has become more widely available thanks to the compelling depth of information it offers, was selected as the inspection method of choice.
