<P>PROBLEM TO BE SOLVED: To perform printing at a high spot arrangement accuracy by using a coarse positioning of a printing head equipped with ejector positions being separate-arranged at random/unevenly, and a plurality of printing heads in the printing of a printed circuit board. <P>SOLUTION: A spot is printed at the high spot arrangement accuracy by using the coarse positioning of the printing head equipped with the ejector positions which are separate-arranged at random/unevenly, and the multiple printing heads. The spot positions which have been provided from all the printing heads are accurately judged by using a camera, and the printing is performed by a high addressability. The spot arrangement accuracy is determined by the addressability as long as there is reproducibility in the spot position, and also, other system errors can be ignored. <P>COPYRIGHT: (C)2008,JPO&INPIT |
