<P>PROBLEM TO BE SOLVED: To provide a printing squeegee for a printed circuit board, which prevents the occurrence of a warp of the printed circuit board during use of a double-sided simultaneous printing method by enabling surface contact of the printed circuit board with squeegee rubber, and which improves ink chargeability in a hole (via hole) and a through-hole by making vector force added to the printed circuit board by the surface contact in a vertical direction larger than vector force in a horizontal direction. <P>SOLUTION: The printing squeegee for the printed circuit board is composed including, at the end for applying pressure to the printed circuit board, a first chamfer formed at a first angle with reference to the longitudinal direction axis of the squeegee and a second chamfer formed at a second angle with reference to an extension line of the first chamfer. <P>COPYRIGHT: (C)2012,JPO&INPIT |
