Abstract

The present disclosure provides a stencil printer comprising a stencil support and a clamping assembly, wherein the stencil support is movable relative to a stencil and comprises a holder and an attraction portion, the holder being movably connected to the attraction portion, and the attraction portion being capable of applying an attraction force to the stencil; and the clamping assembly is capable of clamping or releasing the attraction portion, and when the attraction portion is clamped by the clamping assembly, the holder is capable of moving a predetermined distance relative to the attraction portion in a direction away from the attraction portion and the attraction portion is capable of keeping in position relative to the stencil. The stencil printer in the present disclosure can prevent residual solder paste on the stencil from dripping due to shaking of the stencil when a processing element is away from the stencil.

Claims (9)

1 . A method for controlling a stencil printer comprising a stencil support and a printing device, the method comprising:

moving the stencil support and a processing element to bring the stencil support and the processing element into contact with a stencil;

applying an attraction force between the stencil support and the processing element;

printing the processing element by the printing device while applying the attraction force;

clamping the stencil support to the stencil;

moving the processing element away from the stencil, wherein the stencil support is clamped to and kept in contact with the stencil during the movement of the processing element away from the stencil; and

moving the stencil support away from the stencil.

2 . The method for controlling a stencil printer of claim 1 , wherein the stencil support applies an attraction force to the stencil during printing the processing element and during moving the processing element away from the stencil.

3 . The method for controlling a stencil printer of claim 2 wherein, after the moving of the processing element away from the stencil, the stencil support stops applying the attraction force to the stencil, followed by the moving the stencil support away from the stencil.
