Printing device and printing method

A printing device comprising:

• a squeegee configured to slide on an upper surface of a stencil in which through-holes are formed;
• a moving device configured to move the squeegee back and forth along a specified direction;
• and
• a control device configured to control operation of the moving device, the control device including
• a spreading section configured to spread a viscous material loaded on the upper surface of the stencil in a direction in which the squeegee extends by sliding the squeegee, and
• a printing section configured to squeeze the viscous material that was spread by the extending section into the through-holes of the stencil by sliding the squeegee such that the viscous material is printed onto a board that is closely contacting a lower surface of the stencil,
• wherein
• a moving speed of the squeegee when the squeegee is slid by the spreading section is greater than a moving speed of the squeegee when the squeegee is slid by the printing section.

A printing method of printing a viscous material onto a board that is closely contacting a lower surface of a stencil using a printing device that includes a squeegee configured to slide on an upper surface of the stencil in which through-holes are formed and a moving device configured to move the squeegee back and forth along a specified direction, the printing method comprising:

• spreading the viscous material loaded on the upper surface of the stencil in a direction in which the squeegee extends by sliding the squeegee;
• and
• printing the viscous material that was spread during the spreading onto the board by squeezing the viscous material into the through-holes of the stencil by sliding the squeegee,
• wherein
• a pressing force of the squeegee towards the stencil when the squeegee is slid during the spreading is smaller than a pressing force of the squeegee towards the stencil when the squeegee is slid during the printing.
