Apparatus and methods for inspection of electrical materials and components |
| abstract |
A capacitor has a top plate 2 in the form of a photodiode assay and a bottom plate 2. An RF source 3 is connected between plates 1 and 2. Insulating or semiconducting material to be tested is inserted between the plates 1 and 2 to act as dielectric. Where a printed circuit board or other conductive electrical component is to be tested it forms bottom plate 2. A flying spot scanner 11 produces a modulated light beam 12 which scans the top surface of plate 1. The resulting modula-ted photocurrent envelope is detected and displayed in a display monitor 15 in synchronism with the scanning beam. |
