Abstract
In an apparatus for inspecting cream solder on a PCB, a camera captures an image of cream solder coated on the upper surface of the PCB. A first illuminator illuminates the cream solder such that the light reflected from an edge of the-cream solder, forming an angle with respect to the upper surface of the PCB, proceeds toward the camera. A second illuminator illuminates the cream solder such that the light reflected from the upper surface of the cream solder, parallel to the upper surface of the PCB, proceeds toward the camera. A controller controls the camera, the first and the second illuminators, and for processing the image captured by the camera into a binary image.
