Abstract: 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.

Abstract: Regarding electronic component mounting in which an electronic component having plural solder bumps for external connection on its lower surface is mounted on a board, in an electronic component mounting operation of previously measuring the height position of solder paste on the board on which the solder paste has been printed, and mounting the electronic component on the board on which the solder paste has been printed by a loading head, whether the transfer of the solder paste to the solder bumps is necessary or not is judged on the basis of the measurement result of the height of the solder paste. In case that it is judged that the transfer is necessary, the transfer of the solder paste is executed, and thereafter the electronic component is mounted on the board. Hereby, it is possible to prevent the poor joint in case that a thin-sized semiconductor package which causes easily warp deformation is mounted on the board by soldering.

Abstract: 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.
