ABSTRACT:
A coplanarity inspection device for a printed circuit board includes a base, a supporting disk, a driver, a printed circuit board, a light source, an image acquisition means, and a controller. The supporting disk is arranged on the base, and the driver rotates the supporting disk. The printed circuit board is placed on the supporting disk, and includes a to-be measured side facing downward. The light source projects light beams on the to-be measured side of the printed circuit board. The image acquisition means aims at a specific area of the to-be measured side for image acquisition. The controller is to control the driver, and to store image taken by the image acquisition means. As such, the coplanarity inspection device for a printed circuit board can be employed to inspect whether the coplanarity of the printed circuit board satisfies the standard of setting values in a certain range.
