Abstract

A component mounting line has a screen printing apparatus and component mounting apparatuses. The screen printing apparatus carries in substrates based on substrate carrying-in order data which is determined so that alternate carrying-in in which a first type substrate and a second type substrate are alternately carried in and continuous carrying-in in which the first type substrate or the second type substrate which has a shorter line tact time is continuously carried in are mixed.

First claim

What is claimed is:

1. A component mounting method in a component mounting line including a screen printing apparatus that prints paste on a substrate and a plurality of component mounting apparatuses that are arranged in series on a downstream side of the screen printing apparatus and perform a component mounting-relevant operation on the substrate on which the paste has been printed by the screen printing apparatus, the screen printing apparatus including a mask in which a first pattern-forming area in which a first pattern corresponding to a first type substrate is formed and a second pattern-forming area in which a second pattern corresponding to a second type substrate is formed are arranged in a predetermined pattern arrangement direction, a substrate support unit moving mechanism that moves a substrate support unit supporting a substrate in the pattern arrangement direction below the mask and that selectively brings the substrate into contact with one of the first pattern-forming area and the second pattern-forming area, and a print head that prints the paste on the substrate selectively brought into contact with one of the first pattern-forming area and the second pattern-forming area by moving over the mask, each of the plurality of component mounting apparatuses including a first substrate carrying lane and a second substrate carrying lane which are arranged in the pattern arrangement direction, the component mounting method comprising:
a first operation step in which the each component mounting apparatus carries the first type substrate on which the first pattern has been printed in the first substrate carrying lane and performs a component mounting-relevant operation on the first type substrate;
a second operation step in which the each component mounting apparatus carries the second type substrate on which the second pattern has been printed in the second substrate carrying lane and performs a component mounting-relevant operation on the second type substrate;
an alternate carrying-in step in which the screen printing apparatus alternately carries in the first type substrate and the second type substrate; and
a continuous carrying-in step in which the screen printing apparatus continuously carries in the first type substrate or the second type substrate which has a shorter line tact time.

2. The component mounting method according to claim 1 , wherein the continuous carrying-in step is periodically repeated and the period is determined based on a line tact time of the first type substrate and a line tact time of the second type substrate.
