摘要:
In an electronic components mounting process fabricating a mount circuit board due to an electronic components mounting system formed of a plurality of electronic components mounting apparatuses by connecting them to each other, data of solder paste position which is printed on the circuit board is transmitted as feedforward data to an electronic components placement apparatus and a placement state inspecting apparatus. A control parameter which controls a placing position in a components placement operation due to the electronic components placement apparatus and an inspection parameter which indicates a standard position of the components in a placement state inspection are updated on the basis of the soldering position data. Therefore, it is possible to achieve a precise mounting by effectively and properly using inspection information obtained from each process.

An object is to provide an electronic component mounting method in which an adequate component mounting work to which a check result is correctly reflected is enabled and it is possible to satisfy both reduction of the failure occurrence rate and improvement of the working efficiency. An electronic component mounting apparatus in which an appearance checking section which checks a board to detect existence or non-existence of a failure item, and a component mounting section which transfers and mounts an allocated mounting object component to the board in which the check is ended are integrally disposed includes a mounting availability determination processing section 28d which determines an availability of an execution of an operation of mounting the mounting object component, based on a result of detection of a failure item. In a mounting availability determining process, an availability of an execution of a mounting operation for the mounting object component is automatically determined based on preset failure patterns of the detection result.

摘要:
One objective of the present invention is to provide an electronic component mounting system and an electronic component mounting method that can prevent a mounting defect due to a positioning error in the direction of the thickness of a substrate, and that can deliver a specific mounting quality. According to an electronic component mounting system, which is constituted by coupling a plurality of apparatuses used for mounting electronic components, the height measurement device 22 of a printing inspection apparatus measures the heights at height measurement points, designated on the upper face of a substrate, and outputs the measurement results as substrate height data. Then, once the substrate has been delivered to an electronic component placing apparatus, the substrate height measurement apparatus again measures the height of the substrate at specific height measurement points to obtain substrate height correction data, and based on the initial substrate height data and the substrate height correction data, updates a control parameter for controlling the component placing operation performed by a loading head. In this manner, discrepancies in the positions of the heights of individual substrates can be accurately corrected, and mounting defects due to positioning errors in the direction of the heights of the substrates can be prevented.
