Abstract

A board printing apparatus includes a board working table, a first printing table, a second printing table, and a control portion controlling printing operations. The control portion is configured to perform second printing on a board held by the board working table by a large component mask of the second printing table after a first printing performed on the board held by the board working table by a small component mask of the first printing table.

First claim

What is claimed is:

1. A board printing method of a board printing apparatus including a first printing table and a second printing table each configured to print a viscous material on a plurality of boards, the method comprising steps of:
performing first printing on a first board of the plurality of boards held by a first board working table by a small component mask of the first printing table;
performing second printing on a second board of the plurality of boards held by the second board working table by a large component mask of the second printing table; and
after the first printing, moving the first board working table in a first direction in the horizontal direction and moving the second printing table in a second direction in the horizontal direction opposite the first direction to thereby align position coordinates of the first board working table and the second printing table and align position coordinates of the first board and the large component mask of the second printing table, wherein
a board printing operation of the first printing on the first board is performed during performance of a board printing operation of the second printing on the second board, and
the movement of the second printing table in the second direction occurs during performance of a board printing operation of the first printing table.

2. The board printing method according to claim 1 , further comprising a step of performing a printing preparation operation performed for one of the step of performing the first printing by the first printing table and the step of performing the second printing by the second printing table during a board printing operation of the other of the step of performing the first printing by the first printing table and the step of performing the second printing by the second printing table.

3. The board printing method according to claim 1 , further comprising a step of at least one of:
moving the second printing table closer to a printing position during a board printing operation of the first printing table,
lowering the second printing table from a large component mask plate releasing height position to a standby height position; and
performing mask recognition of the large component mask of the second printing table using a mask recognition camera during a board printing operation performed by the first printing table using the small component mask.
