ABSTRACT:
In a method and a device for mounting an electronic component, a solder paste is printed on lands of a substrate with the use of a mask having a projecting part at a portion facing the substrate and positioned to between neighboring lands, and the projecting part prevents the solder paste on of the neighboring lands from flowing so as to come in contact with a other of the neighboring land to cause a shortcircuit between the neighboring lands.
