<p>A stencil printer (10) includes a frame (12), a stencil (18) coupled to the frame, a substrate support (28) coupled to the frame to support a substrate in a print position, and a print head (20), coupled to the frame, to deposit and print viscous material over the stencil. The print head includes a squeegee blade (38) configured to engage the stencil, a squeegee blade mount (44) configured to house the squeegee blade, a squeegee blade movement mechanism configured to move the squeegee blade mount in a z-axis direction from a raised position in which the squeegee blade is spaced from stencil and a lowered position in which the squeegee blade engages and applies a force on the stencil, and a connector (46, 48) configured to pivotally connect the squeegee blade mount to the squeegee blade movement mechanism. The connector includes a load cell (76) configured to measure force of the squeegee blade against the stencil.</p> |
