Abstract
Printed circuits on plates of epoxy resin reinforced by glass fibres or on glass or ceramics are deformed by electrical loads applied to them. These deformations can be made visible by real-time holography. This testing method reveals concealed defects such as hairline cracks, circuits peeling off the plates or air cavities in multi-layer plates.
