Abstract:
An apparatus for inspecting a board is shown. The board inspection apparatus includes at least one illuminating module, an imaging lens, a first beam splitter, a first camera, and a second camera. The illuminating module provides light to an inspection board and the imaging lens transmits a light reflected from the inspection board. The first beam splitter transmits a portion of the light transmitted from the imaging lens and reflects the rest of the transmitted light. The first camera image-captures by receiving the light that transmits the first beam, and the second camera image-captures by receiving the light reflected from the first beam splitter. Therefore, by using one imaging lens to inspect the inspection board, the decrease in accuracy caused by the different optical axis or magnification may be prevented.
