ABSTRACT:
A stencil printer includes a frame, a stencil coupled to the frame, a substrate support coupled to the frame to support a substrate in a print position, and a print head, coupled to the frame, to deposit and print viscous material over the stencil. The print head may include a squeegee blade configured to engage the stencil, a squeegee blade mount 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 configured to pivotally connect the squeegee blade mount to the squeegee blade movement mechanism. The connector may include a load cell configured to measure force of the squeegee blade against the stencil. Other embodiments and related methods are further disclosed.
