COMPONENT MOUNTING LINE AND COMPONENT MOUNTING METHOD

PROBLEM TO BE SOLVED: To provide a component mounting line and a component mounting method for carrying out screen printing for different kinds of substrates simultaneously without requiring any complicated substrate supply system.SOLUTION: The component mounting line includes two screen printers 11A and 11B each equipped with: a substrate carrying-in section 12 in which a substrate is carried from an upstream side of the component mounting line; a printing execution section 13 which prints the carried-in substrate 4; a substrate carrying-out section 14 which carries the substrate 4 having been printed to a downstream side; and a substrate moving stage 15 which receives the carried-in substrate 4, positions the substrate 4 at the printing execution section 13, and moves the substrate 4 having been printed to the substrate carrying-out section 14. The two substrate carrying-in sections 12, the two printing execution sections 13, and the two substrate carrying-out sections 14 are provided at positions which are symmetrical with respect to a vertical symmetry plane S extending in the carrying direction of the substrate 4 of the component mounting line 3, respectively, the printing execution sections 13 being provided more apart from the vertical symmetry plane S than the substrate carrying-out sections 14.
