Abstract
A light-transmissive support disk supports a tube for attracting an LED chip, and a light-transmissive electrically conductive film is disposed on the support base. The LED chip is electrically connected to a negative terminal of a DC power supply by the light-transmissive electrically conductive film. An imaging unit is disposed coaxially with the tube and has a CCD camera for capturing an image of a light-emitting state of the LED chip via the support disk and a cover member when the LED chip attracted by the tube emits light. The light-emitting center of the LED chip can be detected accurately, and bonded easily and highly accurately on a board at a desired position thereon.
