ELECTRONIC COMPONENT MOUNTING METHOD AND ELECTRONIC COMPONENT MOUNTING SYSTEM

摘要

An electronic component mounting system includes a screen printing apparatus, a coating unit and an electronic component mounting apparatus. The screen printing apparatus supplies a solder paste to first specific lands of a board, using a mask plate that includes a stepped portion and pattern holes formed so as to correspond to the first specific lands. The coating unit coats the solder paste on second specific lands of the board which are positioned in a region of the board overlapping the stepped portion of the mask plate and a vicinity of the stepped portion when the screen printing apparatus supplies the solder paste using the mask plate. The electronic component mounting apparatus mounts the electronic components on the first and second specific lands to which the solder paste is supplied through the screen printing apparatus and the coating unit.

1. An electronic component mounting method of using a solder paste to mount electronic components on a board provided with a plurality of first lands included in a first group and a plurality of second lands included in a second group, the method comprising:
supplying the solder paste to the board, using a mask plate which includes a first part, a second part having a different thickness from that of the first part, and a stepped portion that is a boundary between the first part and the second part, and includes pattern holes formed so as to correspond to the plurality of first lands in the first and second parts; supplying the solder paste to the plurality of second lands, using a coating unit for coating the solder paste; and mounting the electronic components on the first and second lands to which the solder paste is supplied, wherein the second lands included in the second group are disposed in a region of the board, which overlaps the stepped portion of the mask plate and a vicinity of the stepped portion, when the solder paste is supplied using the mask plate.
