Printed circuit board testing system with page scanner

摘要

A method for verification of components installed on a printed circuit board includes the step of capturing an image of an entire printed circuit board and components mounted thereon using a scanning device. After it has been determined that a printed circuit board having no defects, the scanned image of the circuit board has no defects is stored in a memory. The image of the entire printed circuit board under test, and having potential defects is then captured using a scanning device. The image of the printed circuit board under test is then stored in a memory. The stored image of the printed circuit board having no defects is then overlaid in registration with the stored image of the printed circuit board with potential defects on a display in alternating sequence in order to visually provide an indication of a defective component or defective component placement on the printed circuit board under test to an operator.
