The above-mentioned object is a flexible mask having a cutout hole that allows the solder paste to pass through, and a solder applying unit that presses the flexible mask and moves the flexible mask to print the solder paste on a substrate. In a solder paste printing machine having, a solder paste printing machine characterized by having a plate separating mechanism that moves in conjunction with the movement of the solder applying means and promotes plate separation between the flexible mask and the substrate.

As the plate separating mechanism, for example, a wire may be provided between the flexible mask and the substrate, and the wire may be moved in association with the movement of the solder coating means from the rear in the movement direction in conjunction with the movement. As a result, since the plate separation angle of the flexible mask can be made large and always constant, the amount of solder paste carried away to the flexible mask side is reduced.

In the solder paste printing machine of the present invention, immediately after printing, the plate separating mechanism rapidly separates the flexible mask such as a metal mask from the substrate, and thereby a rapid shear rate is generated between the solder paste and the flexible mask. give. Due to the thixotropic property that the viscosity decreases in proportion to the shear rate, which is the characteristic of the solder paste, the amount of the solder paste carried away to the flexible mask side is reduced. Therefore, the printing amount of the solder paste can be made uniform.
