Abstract
A method for checking the proper dispensation of glue onto a circuit board in manufacture includes the use of fluorescent materials in such glue, activating a light source to illuminate a circuit board when the circuit board is placed on an electronic device, and controlling an image capturing device to capture an image of the circuit board. The image captured by the capturing device is compared with a standard stored image of the circuit board, and a determination is made as to whether the circuit board passes test according to the comparison.
