PROBLEM TO BE SOLVED: To provide an electronic component mounting apparatus, which is able to adjust parallelism between a tool and a stage required at the pressing mounting of COG(chip-on-glass) or TCP(tape carrier package) in a short time, to evaluate it quantitatively, and also to provide a method therefor. SOLUTION: This apparatus includes tools 35 which are disposed under lower ends of mounting heads 30 for pushing electronic components, a tilt adjusting mechanism positioned at a position higher than the tools for adjusting front, back, right and left tilts of the tools, a transparent stage 181 for carrying thereon an object on which the electronic parts are to be mounted, an illuminating device 90 for illuminating light on an object-carrying surface of the stage, and an image-pickup device 30 for detecting Newton interference fringes, based on light received from the illuminating device with the tools contacted with the object-carrying surface of the stage. Parallelism of the tools to the stage is adjusted by a tilt adjusting mechanism so that the Newton interference fringes are positioned equal in forwards, backwards, right and left directions with respect to a center of the tools, and then the electronic components are mounted on the object carried on the stage by means of the tools. |
